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.
Transparent Pricing — No Surprises
I publish my rates because clients who know what to expect make better partners. All prices are in USD unless agreed otherwise.

All rates quoted in USD. Timezone overlap of at least 4 hours maintained for any client timezone.
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?
My hourly rates run from $35/hr for standard maintenance work to $85/hr for specialist work such as AI integration and architecture design — most projects land in the $45–$55/hr tier. Fixed-price engagements start at $2,500 for a 2–4 week sprint; a typical MVP build starts around $8,000.
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 for projects over $15,000. 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.
