Most engineers just write code. I build profitable systems. From architecture to App Store deployment, I own the entire product lifecycle — so you can stop worrying about execution and focus on scaling.
★ Flagship Product
TestersConnect
Crowdsourced QA, redefined.
A production-grade marketplace that connects indie developers with vetted testers — turning vague feedback into structured, validated, paid bug reports.
The Problem
Indie devs can't find reliable testers.
Indian indie developers ship broken products because their only testers are friends who give vague feedback. Skilled testers have no platform to earn.
The Solution
A marketplace that pays testers for quality.
Devs post tasks with coin budgets. Testers submit structured reports. AI validates quality before coins release. Razorpay converts coins to real rupees.
How It Works
Developer posts a task
Describe the app, target devices, and coin budget.
Testers apply & test
Vetted testers install the app, submit structured bug reports.
AI validates reports
Duplicate filtering & authenticity checks run automatically.
Coins convert to cash
10 coins = ₹1. Withdraw via Razorpay; devs get clean data.

/ About Me
Why I build products.
As an indie developer I couldn't find reliable testers for my apps. That frustration became TestersConnect — a real product, not a side project.
I approach every system with a founder's mindset: what's the user outcome? Not tickets. Impact.
I don't just write code. I architect, build, and deploy systems that are designed to scale. If you need a builder who owns the outcome from end-to-end, you've found one.

Let's work together.
I partner with ambitious teams to ship production-grade software. If you're looking for an engineer who cares about your revenue as much as the codebase, let's talk.
