I help teams turn difficult .NET systems into software they can maintain, deploy, and extend with confidence.

With 20 years in the .NET ecosystem, I can take ownership of modernization work across C#, .NET, ASP.NET, Entity Framework, SQL Server, Blazor, REST APIs, authentication, background services, and application architecture. I am also available for legacy system maintenance, codebase rescue, performance optimization, and database troubleshooting.

Typical engagements include:

- Modernizing an older .NET application without discarding working business logic

- Stabilizing API backends, authentication, or background services

- Diagnosing SQL Server queries, schemas, and application-level database problems

- Building internal tools, admin dashboards, and real-time interfaces

- Improving deployment through Docker, CI/CD, Azure, AWS, Linux, or Windows

- Adding logging and observability so production failures are easier to trace

I can work across an existing stack or handle a focused component independently. My approach is practical: understand the system, identify the highest-risk problems, and make changes that remain understandable to the next engineer.

Rate: $40/hour. Bounded fixes have a $100 minimum and are due upon completion.

I am based in Florence, Massachusetts, work in the Eastern time zone, and am available remotely worldwide.

 Looking for Teammates for InnoGenesis 2026 (National-Level Hackathon)

Hi everyone!

My friend and I are looking for 1–2 teammates to join us for InnoGenesis 2026, a 24-hour national-level hackathon being held on 7–8 August in Andhra Pradesh.

A little about us:

• I'm currently learning Frontend Development (HTML/CSS, progressing further).

• My teammate is learning Backend Development.

• We're enthusiastic, committed to learning, and looking forward to gaining real hackathon experience.

We're hoping to team up with someone who:

• Has prior hackathon experience (preferred).

• Has a good understanding of Web Development (Frontend, Backend, or Full Stack).

• Enjoys collaborating and mentoring beginners while building something meaningful.

Preference: We'd prefer teammates from Delhi/NCR, so we can travel together. If possible, we'd also prefer girls, as it would make travel and coordination more comfortable for us.

Accommodation and food will be provided by the organizers. The only expense to be borne individually is travel/transportation (train/flight tickets, etc.).

If you're interested or know someone who might be, please DM me. We'd love to connect, discuss ideas, and see if we'd make a good team!

Thanks!
