The Journey So Far
Independent InternshipJul 2026 — Nov 2026Remote — Independent Internship
Fullstack Developer (Backend Focus)
PT AIGRA EON Indonesia
Sole backend developer for DEB Smart Hatchery, an IoT sea turtle egg incubation monitoring system with ESP32/Modbus sensors. Designed multi-channel alerting (Firebase Cloud Messaging, self-hosted WhatsApp via OpenWA, email) with fail-open resilience to third-party outages, and built production infrastructure from scratch — GitHub Actions CI/CD with a self-hosted runner, Docker Compose, nginx, and Cloudflare across parallel production/staging environments. Also contributed Customer & RBAC modules and Playwright E2E tests to Aigra (a Mini POS/ERP for mushroom cultivation), and built the Accounting module end-to-end for RIMS (a car-workshop management system) — automated journal posting and resolved real concurrency bugs (over-receipt, document numbering race) via self-audits.
