Backend engineer who ships end-to-end — from schema to production.

I'm Tanishq Joshi — 7.5+ years building production APIs, AWS serverless systems, and AI-powered products. I've designed, built, and launched two live products solo, and I lead a serverless & AI platform team at TCS by day.

Kaarters ↗

Founder & sole engineer · 2025—present · kaarters.com · github

A live B2B platform for FMCG distributors — retailers, delivery riders, routes, and order fulfillment in one place. I designed the relational data model end-to-end: distributors, riders, retailers, routes and stops, and an order lifecycle with status transitions, payment-collection tracking, and audit notes.

04About
the short version

I like owning the whole surface of a feature — the data model, the API contract, the infrastructure, and the pixels people actually touch. Shipping is the job.

Over seven years I've gone from building CMS modules to architecting serverless platforms across 10+ AWS accounts, leading a team of five along the way. Nights and weekends, I build products: Kaarters for FMCG distributors, CreateFreeResume for anyone who's ever fought a resume-builder paywall.

Lately I'm deep in LLM-powered systems — RAG pipelines with vector search, OpenAI and Claude API integrations, and AI-assisted automation that cut my team's QA turnaround by 40%. I'm looking for product engineering roles at early-stage startups where I own features from schema to ship.
