Experience

Founder & Lead Engineer · Tag-Along Ltd (TagRides)

2025 — Present

Lagos · Solo build · Go · Flutter · Distributed systems · MQTT

Lagos-targeted route-shared mobility platform — designed, built, and deployed solo across backend, mobile, web, and infrastructure.

Architected 9 production Go microservices behind a Kong gateway: auth, driver, geolocation, orchestrator, notification, rating, wallet, analytics, admin — plus an init bootstrap and a simulator for stress-testing the matching algorithm without live drivers.
Built real-time location pipelines on MQTT (EMQX) and Kafka, with Tile38 for geospatial proximity, PostGIS + OSRM + Valhalla for routing.
Engineered a clean-architecture Flutter app (Android, iOS, Web): 575 Dart files, 38 screens, BLoC state management, MQTT5 streaming, Google Maps with custom marker pipelines, Paystack payments, Firebase auth, Google Sign-In with a custom web platform-view shim.
Wrote a complete brand system (BRAND.md) — color tokens, type scale, lockups — codified across the Flutter theme and the Next.js 16 marketing site so app and web read as one product.
Delivered Lighthouse 90+ on the marketing site with Next.js 16, React 19, Tailwind 4, Motion v12, and Lottie.

2026 · 48-hour sprint

LiteLLM · Docker · Nginx · Let's Encrypt · Azure AI Foundry

Multi-tenant LLM API gateway reselling Azure AI Foundry capacity through virtual keys.

LiteLLM + Postgres in Docker, behind Nginx with automated Let's Encrypt rotation. Public HTTPS endpoint live at ai.tagrider.com.
Per-buyer virtual keys with model allowlists, daily-resetting budgets, and spend tracking across Anthropic and OpenAI families.
Diagnosed and patched upstream API edge cases at the nginx layer (header stripping for anthropic-beta values Foundry rejected) to maintain compatibility with Cline, Claude Code, and Cursor.
Two paying-prospect keys live within 48 hours of public launch.
