IoT Prepaid Utility Metering System

Netflow

Jun 2026

A NestJS + MySQL backend streaming live MQTT telemetry from 2,444+ smart meters into prepaid token billing, plus the two React frontends (building-manager dashboard, resident web app) that consume it.

13-detector anomaly engine (backflow, tamper, sensor faults, MCB trips, and more), backed by 166 unit tests
Multi-tenant access secured with Google OAuth 2.0, JWT, and RBAC across buildings
Background job queue (BullMQ/Redis) fans out OTA firmware updates and notification delivery

Genealogy Platform

Genyra

Mar 2026

Built on a shared-type monorepo (NestJS/Fastify backend, Next.js frontend, PostgreSQL via Prisma) for one real family, replacing manual spreadsheets and photos with an interactive, node-based family tree. Secured with Google OAuth 2.0, argon2id-hashed refresh tokens, and Zod-validated input on every request.

Multi-phase auto-layout engine positions nodes across generations, handling multi-marriage and overlapping-branch cases without manual placement
Interactive React Flow canvas supports multi-parent and non-linear relationships, not a strict single-lineage tree
BFS-based consanguinity checks flag close-relative conflicts up to 3 generations before a relationship can be saved
Fixed a Fastify/Passport OAuth crash: Fastify's reply object lacks Express's res.setHeader, which Passport's redirect step calls internally

Public-Transit Data Platform

Started as a rider-facing mockup of a TransJakarta app with bus-occupancy monitoring built in (a simulated mock, not a live feed), then extended into a real analytics backend on TransJakarta's own official GTFS feed (NestJS API, Next.js frontend, PostgreSQL, plus a Go microservice for spatial analysis) computing real service-frequency, coverage, and transfer-network metrics across all 240 routes and 8,091 stops. The demo replays buses along their real route paths and recommends the best time to ride each route, peak hours included.

Go-based spatial-hash walkshed engine computes real 500m coverage for all 8,091 stops, avoiding a ~130M-calculation naive nearest-stop search
Batched ingestion pipeline loads all ~252,000 real GTFS rows (agency through shapes) into Postgres in under 600 round trips instead of one row at a time
Best-time-to-ride advisor combines each route's real published bus frequency with a typical commuter demand pattern to flag peak hours, labeled as an estimate rather than measured ridership
Fleet View simulates bus positions along TransJakarta's own real shape polylines from the feed's real schedule, since the feed publishes no live vehicle-position API
