  • Drifto

    drifto.app ↗

    Event management and ticketing, live in production. I co-founded it and built every layer of the backend.

    • Spring Boot backend on AWS powering web, iOS and Android clients — event management, authentication and Paystack payments for 500+ users at ~95% ticket fulfillment.
    • Payment pipeline with idempotent webhooks and async processing, preventing duplicate charges; ~700ms average responses under live-event spikes at 99.5% API uptime.
    • End-to-end ownership: database schema, RESTful APIs, payment infrastructure and security — from empty repo to live, revenue-generating product.

  • Role AI

    live demo ↗

    An AI assistant that adapts to your role on an engineering team — requirements, design, or analysis.

    • FastAPI backend routing role-specific AI responses for project managers, developers and security engineers.
    • PostgreSQL + pgvector retrieval over project files, chat history and generated design artifacts — with design-decision logging, approval tracking and LLM context injection.
    • Architectural discussions rendered live — flowcharts, UML and ERDs drawn via Mermaid as you talk — with decision tracking built in.
    • Next.js App Router frontend in TypeScript and Tailwind CSS, with Google OAuth and custom JWT auth.
