Let's Build Something Together
I'm a freelance .NET Technical Lead with 8+ years of experience. I work with startups and growing businesses to build Blazor web apps, WPF desktop tools, and production-grade APIs — on time, within budget, and with clean code you can maintain.
Quoted Against Your Scope — No Surprises
Every project is different, so I quote against the actual brief rather than a menu. Want a number before you talk to anyone? Run your brief through the free cost estimator for an instant ballpark, no sign-up needed. All quotes are issued in USD unless agreed otherwise.

What I Build
Blazor Web Applications
Full-stack Blazor Server or WASM applications — from SaaS platforms to internal business tools. Clean architecture, real-time UI, and solid API design.
WPF Desktop Software
High-performance Windows desktop applications with rich XAML UIs, real-time data grids, charting, and business logic — built for demanding industries like fintech and healthcare.
API Development & Integration
RESTful APIs, background job pipelines with Hangfire, OAuth 2.0 integrations, and third-party platform connections (Zoom, Clio, Lawmatics, payment gateways).
Legacy .NET Migration
Modernise your old WinForms, .NET Framework 4.x, or WebForms app to .NET 8/9 with Blazor or ASP.NET Core — without breaking what already works.
Architecture & Technical Lead
Need a senior hand to define your system architecture, review code, set up CI/CD, or guide your dev team? I can step in as a fractional technical lead.
End-to-End MVP Build
Got an idea? I'll help you scope, plan sprints, and ship a working MVP fast — handling everything from database design to deployment on Azure or Vercel.
What You Get
Fast Onboarding
I start contributing on day one — no lengthy ramp-up or hand-holding required.
Outcome-Focused
I measure success by what ships and what it saves you — not hours logged.
Remote-Ready
Async-first, timezone-flexible, and experienced working with distributed teams.
No Lock-in
Clean, documented handover at the end of every engagement. You always own your code.
Weekly Demos
You see working software every sprint — no black boxes or month-long silences.
Full-Stack Depth
From database schema to UI — I handle the whole vertical, not just one layer.
How We Work Together
Discovery Call
Free 30-minute call to understand your project, goals, constraints, and timeline.
Proposal & Quote
Detailed scope document with deliverables, milestones, timeline, and fixed or hourly pricing.
Sprint Delivery
Weekly sprints with demos. You see working software every week — no black-box development.
Handover & Support
Clean code handover with docs, deployment, and 30-day post-launch support included.
Common Questions
How much does it cost to hire a freelance .NET developer?
It depends on scope, complexity, and how well-defined the spec is — a maintenance retainer and a multi-module MVP are not comparable numbers, and any developer quoting you before seeing the brief is guessing. Two ways to get a real figure: run your brief through the free AI cost estimator on this site for an instant ballpark, or book a free 30-minute discovery call and I'll quote a fixed price against the actual scope.
Do you work on existing codebases or only new projects?
Both. A large share of my work is on existing Blazor, ASP.NET Core, and WPF codebases — bug fixes, new modules, refactoring, and legacy .NET Framework migrations. You don't need a greenfield project to hire me.
How do payments work?
Fixed-price projects are 50% upfront and 50% on final delivery, with milestone payments available on larger projects. Retainers are invoiced monthly in advance. I accept bank transfer (SWIFT/SEPA), PayPal, and Wise, in USD, GBP, AED, EUR, or INR.
Who owns the code?
You do. Full source code ownership transfers to you on final payment, including the Git repository with a clean, documented commit history. There is no lock-in — every engagement ends with a complete handover.
Do you sign NDAs?
Yes, I sign NDAs on request before any project details are shared. Confidentiality is standard practice for my client work.
What timezone overlap can I expect?
I'm based in India (IST) and maintain at least 4 hours of working overlap with any client timezone — US, UK, Europe, Gulf, or Australia. I work async-first, so progress doesn't depend on meetings.
What does a project include?
Every engagement includes weekly progress demos with working software, a documented Git repository, 30-day post-launch support for bugs and questions, and full code ownership. Third-party service costs (hosting, APIs) and UI/UX design are quoted separately.
