CLIVE HAPADZIWI
I design and build production systems — high-throughput Go APIs, .NET backends, React frontends, and ESP32 firmware. Focused on clean architecture, measurable impact, and reliable delivery.
Production systems I've designed and built — from IoT firmware to full-stack web platforms.
IoT poultry brooder controller. ESP32 firmware with FreeRTOS task scheduling manages DHT sensors, relays, and MQTT telemetry. Go backend aggregates sensor data; Android app provides remote monitoring and alerts. Reduced chick mortality from 34% to 6% over 28-day field trial.
Wellness analytics dashboard for tracking intern mood and task completion. Real-time updates via Supabase PostgreSQL change data capture with optimistic UI. TypeScript throughout for end-to-end type safety. React frontend with component-based architecture.
Property listing platform with Go REST API and PostgreSQL. Geospatial queries for location-based property search. Google OAuth authentication flow. Next.js frontend with server-side rendering and incremental static regeneration.
Institutional website with dual student and admin portals. Enrollment management system, grade publishing, and announcement feeds. Server-rendered pages for SEO. Supabase backend with Row Level Security for multi-tenant data isolation.
