Who should contact me

I am Abhinav Sinha, a full-stack developer and AI tools builder based in India. I run sinhaabhinav.in, build browser utilities, and write about what I actually use in production — Next.js, React, Spring Boot, LangGraph, and technical content systems.

The best messages are specific. Tell me what you are building, what is broken, or what outcome you want. "Need a developer" is fine as a start, but "Need a Next.js dashboard with JWT auth and a Postgres backend" gets a much faster, useful reply.

What I can help with

• Full-stack web apps — React, Next.js App Router, Node, Spring Boot
• Generative AI integrations — chatbots, RAG pipelines, agent workflows
• SEO and GEO — sitemaps, structured data, llms.txt, Core Web Vitals
• Technical content systems — article structure, publishing workflows, and site reviews
• Freelance or contract work — fixed scope or ongoing support

What happens after you send a message

I read every submission personally. You will usually hear back within one business day. If the project is a good fit, I will ask a few clarifying questions, share a rough timeline, and suggest next steps. If it is outside my stack or bandwidth, I will say so directly instead of leaving you waiting.

Prefer email? Write to abhinavraj350@gmail.com. You can also connect on LinkedIn or read my about page and blog first to see the kind of work I publish.
