Curriculum Vitae — The full build log

Williams Balogun

AI-Augmented Full-Stack Engineer · React · Node · Python · Agents

Full-stack engineer with 4 years shipping production apps in TypeScript and Python, increasingly by directing AI to build complete systems end to end. I shipped my own AI job-hunting product (Trajekt), led a multi-agent system that cut task time 40%, and built a quant-research engine disciplined enough to prove its own trading strategy had no edge. The throughline is grounded, high-trust AI that knows when not to act. Most recently I built Orviqo, a WhatsApp receivables agent that returns a question instead of a hallucinated invoice.

Key projects

Trajekt: AI Job-Hunting Platform

Designed and built end to end (founder; design with Ayowande Olubo): discovers startup roles, writes personalised CEO cold outreach, runs mock interviews, grades them, and coaches the gaps.
Five grounded AI stagesbehind one command centre. Every step ties to the real CV & the target company, so you can review it rather than trust magic. Live in beta.

Orviqo: WhatsApp-Native AI Receivables Agent

A WhatsApp AI that logs who owes a Nigerian SMB money, chases debtors politely, and reconciles payments from plain messages. Built on Python, Pydantic AI & FastAPI over a durable SQL ledger.
Engineered a record-vs-ask rigor gate so it returns a question instead of inventing an invoice, with every decision (refusals included) written to an audit trail and pinned by 61 offline tests that run with the LLM faked.

Verdkt: AI Trading System & Research Engine

A multi-timeframe FX/crypto system on MetaTrader 5 plus a walk-forward research engine: pre-registered pass/fail bar, held-out validation, and strictly no look-ahead.
The rigor proved its own strategy had no robust edge before any real capital was at risk. A case study in honest quantitative research over wishful backtests.
