AJANAKU

Fullstack & AI Engineer | Lagos, Nigeria

What I build

Systems that do the hard work.
Interfaces that stay out of the way.

  • I build RAG pipelines, tool-using agents, and MCP servers that actually get things done.

    OpenAIAnthropicLangGraphpgvectorn8n

  • I build products end to end, from the frontend to the backend and the infrastructure running underneath it. TypeScript, Node, FastAPI, whatever fits the job.

    Next.jsFastAPIPostgreSQLAWS

  • I build interfaces that feel good to use without sacrificing performance. Motion has a purpose, and I make sure it still feels smooth on the hardware people actually use.

    GSAPFramer motionCore Web VitalsA11yApperio

  • I build automated trading systems end to end: signal logic, risk management and live execution, plus the tooling that parses raw backtest reports into equity curves and trade journals. The test is whether a signal still holds on data it hasn’t seen, not whether it looks good on a chart.

Trading systems

Strategies & backtests.

Automated trading systems I have designed, tested, and published the source for: signal logic, risk management, and execution, with a parser that turns raw platform reports into the equity curves and trade journals below. Each one links to its source code and full backtest results. Results are historical backtests, not live returns.
