I deliver production-ready embedded solutions from concept to manufacturing. With expertise in both hardware and firmware, I design reliable 2-4 layer PCBs and develop robust firmware for ESP32, STM32, Nordic nRF, and ARM MCUs. My work includes: - PCB Design: Schematic & layout (Altium Designer, KiCad), Gerber files, signal integrity, power design - Firmware: C/C++ for ESP32 (including audio output), STM32, RTOS, drivers, Embedded Linux (Raspberry Pi, Odroid) - Connectivity: BLE, MQTT, HTTP/REST APIs, IoT system integration - Additional: TouchGFX UI, Python automation, AI/CV applications, technical documentation I focus on clean architecture and maintainable code to ensure long-term reliability—not just prototypes. Whether you need hardware designed from scratch or firmware to bring it to life, I can support your full development cycle. Let's discuss your project. I'm available for independent work or remote team collaboration.

I build and stabilize production automation systems and data pipelines for e-commerce and AI workflows. I don't just write scripts; I engineer reliable systems that handle real-world constraints: anti-bot, rate limits, API failures, and strict data validation. What I deliver: • System Stabilization & n8n/AWS Automation: Diagnosed and fixed a failing 5k–8k SKU e-commerce sync. Implemented retry logic, EC2 lifecycle control, and eBay API error handling. System now runs daily without crashes. • Targeted Data Pipelines for AI/RAG: Built bounded retrieval systems to extract, verify, and structure policy documents (PDF + web) from 1,500+ domains. Delivered clean JSON corpus with provenance tracking, rate limiting, and strict validation. • Strict Data Transformation & ETL: Engineered bidirectional JSON ↔ ASCII converters with round-trip safety and schema alignment. Handles complex business logic without data loss. My working style: - Fixed scope, clear milestones. I provide a technical audit/demo before full commitment. - Production-ready code: logging, error handling, documentation, and handover support. - Honest scoping: I'll tell you upfront what's feasible and what isn't. Tech: Python, n8n, AWS (EC2), eBay API, Supabase/PostgreSQL, Playwright/Selenium, JSON/ASCII ETL, CLI tools. English & Vietnamese fluent. Reply within 1 hour.
