About Ayush

Ayush K.Status: Offline
Backend Engineer | Node.js, Python & AI/LLM Integration
Kangra, India - 10:54 pm local time
I build and maintain production backends — the kind that stay up when real users are on them.

My day-to-day work: Node.js/TypeScript and Python (FastAPI) services, PostgreSQL schema design and migrations, Redis caching and rate limiting, JWT authentication across multiple user roles, and real-time streaming over Server-Sent Events.

Most of my recent work is LLM integration — wiring language models into real products and handling the parts that break in production: streaming responses, timeouts on slow model calls, retries, graceful degradation when an upstream AI service fails, and keeping token costs under control. A prototype that works on your laptop is not the same thing as a feature that survives real traffic, and that gap is where I spend most of my time.

I have also integrated third-party providers end to end — payments, SMS, email, and the WhatsApp Cloud API — including the OTP flows, delivery failures, and webhook edge cases that only show up once you are live.

What I am good at:
- Turning an AI prototype into something production-ready
- REST APIs built properly: auth, validation, rate limiting, migrations, error handling
- Debugging the failures that only appear under real load
- Third-party API and webhook integrations that do not silently drop data

If you have a backend that is breaking under real usage, or an AI feature that works in testing but not in production, that is exactly the problem I solve. Send me the details and I will tell you honestly whether I am the right fit.
