AI-First Full-Stack Engineer for SaaS & Scalable Systems
Pune, India - 7:48 pm local time
I don’t just write code.
I design systems, make technical tradeoffs, and take ownership of outcomes.
My core work sits at the intersection of:
Backend architecture & scalable APIs
AI-enabled systems (RAG, LLM integrations, automation)
Performance, reliability, and cost-aware engineering
What I actually do
Design backend systems that scale beyond MVPs
Build and integrate AI features that work in real production constraints
Fix slow, brittle, or over-engineered systems
Reduce operational complexity, bugs, and long-term cost
Take ambiguous requirements and turn them into clear, working solutions
Backend & System Engineering

Postman, Figma (collaboration & API-first workflows)
Agile / remote-first team environments
Why clients hire me
I think in system design, not tickets
I challenge bad technical decisions early
I care about stability, scalability, and ROI, not just shipping
I communicate clearly and take full ownership of what I build
I work best with:
Founders who want things done right, not rushed
Teams that need a senior engineer without full-time commitment
Products where reliability and correctness actually matter
If you’re building, scaling, or fixing something that can’t afford to break, let’s talk.
