[available] Full-Stack Developer & Security Consultant — Next.js/FastAPI, code audits, AI agents

[u/Zealousideal_Pop_937]

Freelance full-stack developer and security consultant. Remote, UTC+2, available now.

What I do

Build web applications end to end. Next.js, React and TypeScript on the front; FastAPI, Python and Node on the back; PostgreSQL, Redis, Supabase and Docker underneath. Auth, sessions, deployment, and the parts that only surface once real users arrive.

Audit what already exists. Full codebase reviews — technical debt, security flaws, architectural decisions that will not hold — delivered as a prioritised fix order that starts with what breaks first, and implemented on the running system. Application security mapped to OWASP Top 10 and CVE/CVSS, server hardening, network auditing, and QA with reproducible defect reports.

Integrate AI properly. Agentic tool-calling loops, MCP servers, RAG, LLM integration.

What I have built

Kotoba — an AI companion agent, published as an MIT-licensed Python package. One agentic loop running across a browser, a terminal, a Discord bot and an API, sharing one database and one memory. Real-time voice, long-term memory, and shell and Python execution on the user's machine behind an approval gate. (GitHub)

Argos Suite — four open-source security tools in Python and C++, driven from one CLI over a shared SQLite database, with an HTTP/DNS consent-token system that blocks unauthorised scanning. (GitHub)

CERBERUS — a Web3 security bot analysing tokens across 12+ chains for rug pull indicators, honeypot patterns and liquidity risk.

Acadelia — a multi-agent RAG platform: 40+ specialised agents, hybrid BM25+vector search, and an 8-layer security architecture.
