I'm Joel J Mathew, a self-taught computer scientist from India who has been coding since I was 12. I've spent the last 15 years building production-grade systems, shipping 257+ projects, and creating startup accelerators that have helped hundreds of founders launch their dreams.
I believe in building fast, shipping faster, and scaling everything. My journey has been one of relentless curiosity, late-night debugging sessions, and an unshakeable belief that technology can solve humanity's biggest problems.
I'm currently the Founder & CTO of Val-X, where I'm building the next generation of startup accelerators powered by AI. I'm also an author, music artist, and open-source contributor who believes in giving back to the community that has given me so much.
When I'm not coding, you'll find me writing about psychology and influence, producing music, or exploring the intersection of technology and human behavior.
My tech stack spans 200+ tools across the full development lifecycle. Here's a quick overview:
| Category | Technologies |
|---|---|
| Frontend | React, Next.js, TypeScript, Tailwind CSS, Vue.js, Svelte |
| Backend | Rust (Axum), Node.js, Express, Fastify, Go, Python |
| AI/ML | TensorFlow, PyTorch, LLMs, RAG Pipelines, Computer Vision |
| Cybersecurity | Red Team (OSCP, OSEP), Blue Team (OSDA), Penetration Testing |
| Database | PostgreSQL, MongoDB, Redis, SQLite, DynamoDB |
| Cloud | AWS, Docker, Kubernetes, Vercel, Netlify |
| Web3 | Blockchain, Smart Contracts, DeFi, Ethereum, Solidity |
