Expert Tech Pilot provides .NET development and legacy application modernization to businesses throughout Northeast Ohio, including Cleveland, Akron, Macedonia, Solon, Independence, and surrounding communities. The work covers new C# applications, failing or undocumented systems, web APIs and integrations, and SQL Server data layers. Each engagement is scoped to the application the business already depends on, with the goal of making it reliable, maintainable, and easier for your team to own.
What this service covers
Most .NET work falls into one of five buckets: building something new, making an existing application reliable, moving an older application forward, connecting .NET code to the rest of the business, or keeping a working system working. The boundaries are practical rather than doctrinal. A single engagement often starts with one and uncovers another.
- Custom .NET development. New internal tools, line-of-business applications, workflow systems, and processing applications built with C# and the .NET stack.
- Legacy modernization. Assessment and incremental improvement of older .NET Framework, Web Forms, WCF, and mixed-technology applications.
- Troubleshooting and maintenance. Root-cause work on failing jobs, slow pages, unreliable integrations, and applications nobody currently owns.
- Web APIs and integrations. APIs that connect .NET applications to internal systems, third-party services, data stores, and identity providers.
- SQL Server and data access. Schema review, query performance, data access patterns, reporting feeds, and safe changes to production data flows.
The common thread is an application the business already relies on. This is not a greenfield product studio, and it is not a body-shop placement. I take responsibility for understanding the system, making a defensible technical decision, and doing the work.
When a .NET system needs attention
Problems rarely announce themselves as architecture problems. They show up as symptoms that the business has learned to work around. A few that justify a closer look:
- The original developer or vendor is gone, and nobody can safely change the application.
- A monthly process has become a manual checklist because an automated job is unreliable.
- Performance has slipped gradually, and the usual fixes — more memory, a restart, a database index — no longer hold.
- Every deployment carries visible risk, or deployments happen only after hours.
- A planned upgrade, migration, or integration has been discussed for years without a credible plan.
- The application works, but it is blocking a business change: a new location, a new product line, a new reporting requirement, or an acquisition.
An initial conversation is usually enough to separate an operational problem from a structural one. If the answer is a settings change, you should hear that. If the application needs a longer plan, the first deliverable should be the plan, not an open-ended development contract.
Custom .NET development
Custom development makes sense when a business process is specific enough that packaged software would require more workarounds than it removes. I build applications with C# and the Microsoft stack, typically as web applications, internal services, scheduled processing jobs, or APIs behind another system.
The design priorities are deliberately unglamorous: clear data ownership, predictable deployment, usable error messages, structured logging, and code the next developer can read. A small application that can be maintained for years is a better outcome than a larger platform that only its author understands.
Typical builds include internal workflow and case-management tools, document and records processing, data validation and transformation utilities, operational dashboards, and integration services that move data between systems that were never designed to talk.
Legacy .NET modernization without a blind rewrite
“Legacy” is not a synonym for “worth replacing.” Many older .NET applications are stable, well understood by their users, and expensive to reproduce. A rewrite can consume a year and return a system with the same business rules, fewer years of hardening, and a new set of defects. The first job is to establish what is actually at risk.
An assessment looks at the application from several angles at once:
- Code and dependencies. Framework version, unsupported libraries, upgrade blockers, duplicated logic, and areas with no tests or documentation.
- Runtime and infrastructure. Hosting model, deployment process, authentication, scheduled jobs, and the parts that fail silently.
- Data. Schema quality, SQL Server dependencies, reporting consumers, retention obligations, and what an application change would do to downstream systems.
- Business criticality. Who uses the system, what happens when it is unavailable, and which functions are genuinely irreplaceable.
From there, modernization can take several forms. Sometimes the right move is a framework or runtime upgrade. Sometimes it is isolating one risky module behind a new API while the rest of the application stays put. Sometimes it is replacing a single integration or retiring a feature that no longer earns its maintenance cost. A full replacement is justified when the platform, the business model, or the operating cost makes incremental work pointless — but that should be a conclusion from the assessment, not the premise.
A written assessment with the current state, the specific risks, the realistic options, and a recommended sequence. The document is useful whether or not I do the implementation.
Troubleshooting and ongoing maintenance
Not every engagement needs a roadmap. Sometimes an application is failing in a way that costs the business money every week, and the immediate job is to stop the bleeding. I take on targeted troubleshooting and ongoing maintenance for .NET applications where the original team has moved on or internal capacity is stretched.
Troubleshooting starts with evidence: logs, event data, database behavior, deployment history, and a reproducible path to the failure. The goal is the cause, not a workaround that hides it. Maintenance work is similarly concrete: security updates, dependency upgrades, bug fixes, small feature changes, deployment hygiene, and documentation that reduces the next person's dependence on memory.
Support can be arranged as a defined monthly block or as a scoped response to a specific problem. It is not a call center. You are working with the person who knows the code.
Web APIs, integrations, and SQL Server
Most business applications are only as useful as the data they can exchange. I design and build web APIs and integration services that connect .NET applications to internal databases, third-party platforms, document systems, identity providers, and reporting tools. That includes API authentication and authorization, retry and failure handling, data mapping, and the operational logging needed to diagnose a failed exchange later.
SQL Server work is often where an integration problem actually lives. A query that was fine at one data volume becomes the slowest part of the day. A schema that grew by accretion makes every change risky. A reporting feed reads production tables directly and pins a workload that should be isolated. I review the data model and access patterns, improve the queries and indexes that matter, and make changes in a way that can be tested and reversed.
The same care applies to identity and deployment. Existing experience includes OAuth 2.0 token services, Microsoft Graph and SharePoint integrations, and Azure DevOps build and release pipelines. Those are implementation details, not a product list — the point is that the integration is designed to be operated, not merely demonstrated.
Modernize or maintain? A practical decision
The decision is not “old versus new.” It is which option gives the business the most reliable system for the next several years at a cost it can absorb. Four questions tend to settle it:
- Is the platform still supportable? If the runtime, libraries, or hosting environment no longer receive security updates, the maintenance option has a hard expiry date.
- Is change still safe? An application that cannot be tested or deployed without fear will slow the business down regardless of how well it runs today.
- Where is the risk concentrated? A single fragile integration or unsupported component may be worth replacing without touching the rest of the system.
- What does the business need next? If the roadmap requires capabilities the current design cannot reasonably support, the modernization case is stronger than a code-quality argument alone.
If maintenance is the right answer, I will say so. A responsible consultant should be willing to recommend the smaller engagement when the evidence supports it.
What an engagement looks like
- A free 40-minute working session. We discuss the application, the symptoms, the business constraint, and what a good outcome would look like. No preparation deck required.
- A scoped assessment. For anything beyond a small fix, I review the code, infrastructure, data, and delivery process, and interview the people who use and operate the system.
- A written plan. You get the findings, the options, the trade-offs, a recommended sequence, and an estimate for the next step. The plan is written for a business reader as well as a technical one.
- Implementation or support. If the plan calls for work, I can do it directly, work alongside your team, or hand it to another developer with enough context to execute.
- Handoff. Documentation, deployment notes, and a clear statement of what was changed and what remains. The goal is a system your organization can own.
Why an independent senior consultant
With a small firm, the person in the sales conversation is the person doing the work. That matters most when a system is poorly documented: the judgment required to make a safe change lives in experience, not in a staffing plan. There is no handoff to a junior team after the contract is signed, and no incentive to extend an engagement by inventing work.
An independent consultant can also supplement an internal team without displacing it. I have worked inside enterprise application groups and know the difference between a contractor who needs to be managed and one who can take a problem, ask the right questions, and return with a working answer. The engagement can be structured to transfer knowledge to your developers rather than create dependence.
Common questions
Can you take over an application another developer built?
Yes. Taking over an unfamiliar system is a normal part of the work. The first step is a bounded assessment so neither side is committing to a long engagement before the code, dependencies, and operational risks are understood.
Do you work with .NET Framework as well as modern .NET?
Yes. Older .NET Framework applications are often where the most valuable and least documented business logic lives. The assessment determines whether an upgrade, isolation strategy, or replacement is the sensible path.
Can you work with our existing developers?
Yes. I can lead a workstream, pair with internal developers, review a design, or take a specific problem off the team's plate. The engagement is shaped around the capacity you actually have.
How do you handle production changes?
Changes are made with a rollback path, a testing approach proportional to the risk, and a clear deployment window. If the existing process has no safe path, improving that process is part of the work rather than an afterthought.
What is the best first step?
Book a free 40-minute working session, or send a short email describing the application and the problem. A few sentences about what is failing, who it affects, and what you want to be true instead are enough to start.
Serving Businesses Across Northeast Ohio
Expert Tech Pilot provides .NET development and legacy modernization services to businesses in Cleveland, Akron, Solon, Independence, Macedonia, and surrounding Northeast Ohio communities. On-site consulting is available when a project benefits from in-person collaboration, with remote services available as well.
For .NET work, on-site time is most useful for meeting the people who use the application, walking through a production process, or working through a decision with the team in one room. The rest of the engagement can be handled remotely, with the same direct access to the person doing the work.
