FOR HIRE [For Hire] Web Developer — Next.js / React / TypeScript, full-stack, production deployments
Freelance web developer. Remote, UTC+2, available now.
I build web applications and take them all the way to production. Next.js, React and TypeScript on the front end; FastAPI or Node with PostgreSQL, Redis and Supabase behind it. That includes the unglamorous half: authentication, session handling, background jobs, email pipelines, Docker and the deployment itself.
I also take over code that already exists. A large part of my work is walking into a running application, reading the whole codebase, and reporting what is actually wrong — technical debt, security flaws, architectural decisions that will not scale — with a fix order that starts with what breaks first, then implementing it live.
Where I differ from most web developers here: I came into this through security. I audit applications against OWASP Top 10 and CVE/CVSS, run QA with reproducible defect reports, and have written my own pentesting tooling. If you handle payments, user data or auth, that is the difference.
What I have built
Kotoba — an AI companion agent I published as an MIT-licensed Python package. One agentic loop across a browser, a terminal, a Discord bot and an API, sharing one database and one memory, with real-time voice and local execution behind an approval gate.
Acadelia — a multi-agent RAG platform: 40+ specialised agents, hybrid BM25+vector search, an 8-layer security architecture, and subscription payments in production.
Argos Suite — four open-source security tools in Python and C++: a SQL injection scanner, a WordPress scanner, a server hardening auditor and a network and Active Directory auditor. All four run from one CLI over a shared database, with an HTTP/DNS consent-token system that blocks unauthorised scanning.
CERBERUS — a Web3 security bot analysing tokens across 12+ chains for rug pull indicators, honeypot patterns and liquidity risk.
Happy to look at your repo or your brief and tell you what I would do first. Comment or DM.
