How this portfolio is engineered

Honest status labels only. If it isn't in the codebase, it isn't marked Implemented.

Engineering LabAI assistant

Security

  • Environment variables

    implemented

    AI keys live in .env.local (gitignored). Server routes only; never NEXT_PUBLIC for secrets.

  • Authentication

    planned

    This portfolio has no user auth. Zumelia uses Supabase Auth (founder-confirmed).

  • Input validation

    implemented

    Assistant and demo API validate message length, shape, and content type.

  • API protection

    implemented

    In-memory rate limiting on /api/assistant and /api/demo.

  • Security headers / CSP

    planned

    Not yet configured in next.config — planned hardening.

Performance

  • Image optimization

    implemented

    next/image with quality caps and local WebP assets for projects.

  • Lazy loading

    implemented

    Heavy assistant/playground UI is route-scoped; not loaded on the home LCP path.

  • Caching

    implemented

    GitHub activity uses Next.js fetch cache with revalidation.

  • Database optimization

    planned

    This portfolio has no database. Zumelia uses Supabase/Postgres (founder-confirmed).

Reliability

  • Error handling

    implemented

    API routes return structured errors; assistant UI supports retry.

  • Loading states

    implemented

    Streaming, empty, and error states in the assistant UI.

  • Retry behavior

    implemented

    Client retry on failed assistant requests.

  • Monitoring

    planned

    No APM/analytics wired yet.

Deployment

  • Git

    implemented

    Local version control for this portfolio.

  • GitHub

    implemented

    Public activity surfaced for username femi1245.

  • CI/CD

    in progress

    No custom CI pipeline in this repo yet — Vercel deploy assumed.

  • Vercel

    implemented

    Projects and portfolio target Vercel hosting.

Currently learning

Continuous technical growth

Not a claim of expertise for every topic — progress indicators for what is being explored.

  • built

    AI engineering

    Grounded assistants, streaming UX, and provider-agnostic adapters.

  • experimenting

    RAG

    Structured retrieval first; vector search designed as a later upgrade.

  • learning

    MCP

    Tool contracts for agents — planned experiments in the Lab.

  • learning

    AI agents

    Constrained tool use over unconstrained chat loops.

  • production experience

    Webhooks

    Signature verification and idempotency (Zumelia payments context).

  • experimenting

    System design

    Clear service boundaries: auth, storage, payments, realtime, AI.

  • production experience

    PostgreSQL (via Supabase)

    Used in Zumelia; portfolio itself remains static TS data.

  • learning

    Redis

    Exploring for rate limits and caching beyond in-memory maps.

  • learning

    Docker

    Local packaging and reproducible environments.

  • learning

    Observability

    Logging and error monitoring for production apps — planned here.
