Are you available for full-time roles right now?

Yes — I'm open to full-time AI engineering, backend, and full-stack roles at startups and product companies, alongside select freelance projects.

What's your tech stack?

AI and backend: Python, FastAPI, and multi-provider LLM orchestration (OpenAI, Claude, Gemini) with structured JSON output, token budgets, and Prometheus metrics — plus RAG and pgvector, and ASP.NET Core, C#, and SQL Server as the enterprise foundation. Automation: Playwright, Selenium, Pandas. Freelance: Next.js, React, Supabase, Razorpay/Stripe, Resend.

Where are you based and do you work remotely?

I'm based in Ahmedabad, India. I work fully remote for freelance clients and open to remote-first or hybrid full-time roles globally.

How much do you charge for freelance projects?

Project-based. A typical SaaS MVP runs $4k–$10k, an AI integration $2k–$6k. Larger builds are quoted after a free 30-minute discovery call.

What kind of projects do you build?

AI features that hold up in production — RAG over your own content, agent workflows, and document-to-output pipelines — plus SaaS MVPs with auth, billing and dashboards, e-commerce with Stripe/Razorpay, and SEO/Core-Web-Vitals work.

How fast do you ship?

A typical SaaS MVP goes from kickoff to live URL in 3–6 weeks. AI integrations land in 1–3 weeks depending on data and surface area.

News Desk — Human-in-the-Loop Story-Discovery Agent

An automated newsroom agent that reproduces an editorial team's morning routine — harvests ~65 primary and ~75 secondary curated source pages across 17 countries for textile/apparel news, scores and de-dupes the best stories with an LLM, confirms each against its primary source, then drafts publish-ready articles. Two-phase with a human in the loop, streamed live over SSE.

Turns the desk's manual morning scan into one click — a deduped shortlist of ~20–30 ready-to-draft story candidates
Two-phase pipeline keeps cost low: discovery runs a cheap model under per-job token and URL budgets, and only editor-picked stories get the expensive full fetch and a stronger drafting model
