Softwarerescueforcomplex.NETandSQLsystems.

I help teams stabilize and simplify .NET/SQL systems through focused legacy fixes, reporting, automation, and a clearer technical baseline.

Mid-level Software Developer (.NET / SQL / Automation)

How I work

Understand the pressure point first, make the smallest sensible intervention, and leave context for the next iteration.

Diagnose
Diagnosis before solutioning.

I take over a chaotic business system, understand it quickly, fix it, document it, and automate repetitive work.

Stabilize
Small verifiable steps over oversized rewrites.

I enter messy .NET/SQL systems, map the real risk fast, define a realistic path forward, and leave behind a clean technical base for the next iteration.

Transfer
Architecture should still be explainable a month later.

The public layer of the site stays intentionally brief for now. More case notes, context, and materials will gradually move from YUP/Notion into publishable form.

Selected projects

Three public work tracks built on the same principles: diagnosis, stabilization, and a transferable result.

Scoping / 2026Legacy .NET Rescue Package

Fast audit and stabilization of an internal .NET application

Legacy .NET Rescue Package

A short engagement focused on issue reproduction, fix/fix proposal, and a concise technical report.

Problem
Production incidents keep happening, reports are inconsistent, and the core bottleneck is unclear.
Approach
Reproduce the issue on realistic data samples. Add telemetry and logging on critical paths. Deliver a fix or isolated fix proposal with risk estimate.

Need to untangle a system rather than add another layer of chaos?

I am open to focused rescue work, integration briefs, and automation by arrangement.
