Surface Build Forge Break Bedrock
SAYAN STACK — LONDON

I build platforms —
then I try to break in.

Full-stack developer and founder at Nuvéxis, shipping production SaaS for the hospitality industry. Independent security researcher on HackerOne in the hours between.

Security research

Outside of building, I hunt for vulnerabilities through HackerOne-hosted programs — web application and API security, within each program's defined scope. Fewer, higher-quality reports over volume; nothing goes in a write-up until the impact is verified and reproducible.

  • 01Recon — map the target, confirm what's in scope
  • 02Manual + tool-assisted testing of the attack surface
  • 03Verify real, reproducible impact — reject false positives
  • 04Clear write-up: proof of concept, steps, severity

About & contact

Full-stack developer and founder, building scalable SaaS products and modern web applications.

Based in London. I work primarily in TypeScript, React, Next.js, Node.js, and PostgreSQL — and reach for Python when the job is a script or a security tool rather than a product. Everything above is real, shipped work: the products are live, the tools are tested, the HackerOne profile is mine.
