I will develop production esp32 iot firmware with AWS cloud backend
Hardware and IoT Specialist
I design PCBs and develop firmware for market-ready hardware. With 160+ successful projects, I specialize in FCC/CE compliant designs that bridge the gap from prototype to mass production.

Has met high performance criteria and has a proven track record for meeting client expectations.
About this Gig
Arduino gets your prototype blinking. ESP-IDF gets your product shipping.
I write ESP32 firmware in ESP-IDF the framework Espressif recommends for commercial deployments using FreeRTOS task architecture, TLS-secured MQTT, and proper fault recovery. The result is firmware that runs unattended for months, reconnects after network drops, recovers from hardware faults via watchdog, and pushes OTA updates without bricking devices in the field.
On the cloud side I integrate AWS IoT Core for device management, Lambda for event-driven processing, DynamoDB for telemetry storage, and S3 for OTA binary hosting. I have shipped this stack in agricultural sensors, industrial monitoring systems, and connected consumer products.
Every codebase I deliver is structured, commented, and documented so your team can own and extend it after handoff.
Clients I’ve worked with
Oasis Water Technologies
Collaborated with multiple teams at Oasis to engineer a highly durable, battery-powered industrial IoT device. Because the device was designed for remote deployments with minimal human interaction, mission-critical reliability was the top priority. I delivered an end-to-end solution, handling the custom hardware design, robust firmware development (including WiFi, OTA updates, and MQTT protocols),

Mobile Outfitters
Partnered with Mobile Outfitters to engineer the core electronics for a high-precision, CNC-style mobile accessory cutting machine. Tasked with solving a complex integration of digital and analog circuits, I managed the full hardware lifecycle—from initial schematic design and high-density PCB layout to troubleshooting and prototype testing. The project resulted in a fully manufacturable, producti

FAQ
Can you extend my existing ESP32 codebase?
Yes, ESP-IDF or Arduino. Share the repo and I will audit it and tell you what needs to change before touching anything.
Does this include AWS account setup?
I write all AWS-side code and provide a step-by-step setup guide. You need your own AWS account. AWS usage costs are separate.
Do you support ESP32-S3 and ESP32-C3?
Yes, full ESP32 family including S2, S3, C3, C6, and H2. I will recommend the right variant for your power, connectivity, and AI acceleration needs.
Can you also design the PCB hardware?
Yes. Message me for a bundled PCB design and firmware package.
