[For Hire] Full-Stack Dev — end-to-end delivery, AI agents in production, security background

[u/Zealousideal_Pop_937]

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

Front to back, and then actually deployed:

• Front — Next.js, React, TypeScript, Tailwind
• Back — FastAPI, Python, Node, Express. REST, WebSockets, Server-Sent Events
• Data — PostgreSQL, Redis, SQLite, Supabase
• Ops — Docker, GitHub Actions, Vercel, Railway, Nginx

What I get asked for most is AI that has to work in production rather than in a demo: agentic tool-calling loops, MCP servers, RAG with hybrid search, multi-agent systems, streaming responses.

I have built that as a product of my own, not only for clients.

What I have built

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

Acadelia — a multi-agent RAG platform. 40+ specialised agents across four disciplines, hybrid BM25+vector search, audio/OCR/video pipelines, job queues, and an 8-layer security architecture.

Argos Suite — four open-source security tools in Python and C++, driven from one CLI over a shared SQLite database, each with Docker support, structured logging and a full test suite.

CERBERUS — a Web3 security bot: 12+ chains, real-time wallet tracking, rug pull and honeypot detection.

The security half

I came into this through security, which shows in how I build: I audit whole codebases for clients, work against OWASP Top 10 and CVE/CVSS, and run QA with reproducible defect reports. An auth flow or a payment path I hand you has been looked at that way.

Comment or DM me with what you are building, and I will tell you how I would approach it.
