I build industrial-grade IoT solutions that don’t just work—they last. Graduating with a 3.92 GPA in Computer Science, I’ve developed a disciplined approach to engineering that balances high-level software architecture with rugged hardware design. My focus is on creating reliable monitoring ecosystems for demanding environments like industrial wastewater treatment (IPAL). Core Capabilities: Lab-Grade Precision: I bypass standard ESP32 limitations by integrating 16-bit ADS1115 ADCs, delivering stable and accurate sensing for TDS, pH, and Temperature. Ruggedized Hardware: My designs feature corrosion-resistant and waterproof housings, specifically engineered to survive constant exposure to chemical waste. Full-Stack Visibility: I develop custom web dashboards that provide real-time data visualization and deep historical analytics. Remote Scalability: Every system I build includes OTA (Over-the-Air) firmware management, allowing me to optimize and troubleshoot your devices from anywhere in the world. I don’t just deliver prototypes; I deliver production-ready assets with clean code and professional documentation. Let’s discuss how I can bring high-precision reliability to your project.

I design robust embedded and IoT systems for real-world deployment — not just prototypes. I specialize in end-to-end system development, from hardware architecture and PCB design to firmware development and field deployment. My work focuses on building systems that are stable, maintainable, and reliable over long-term operation. I have hands-on experience across multiple platforms including ESP32, STM32, Arduino, and PLC-based systems, along with industrial communication protocols such as Modbus (RTU/TCP), RS485, and SCADA integration. What differentiates my work is a strong engineering focus on system reliability and field performance. I systematically analyze: – sensor signal integrity – power architecture and regulator design (LDO, buck, boost) – grounding, noise, and EMI considerations – interface compatibility and system robustness to ensure consistent and dependable operation in real-world environments. I support projects from concept to deployment, including: – system architecture design – schematic development and PCB layout (KiCad) – firmware architecture (non-blocking / RTOS-based) – system integration, validation, and debugging – field-level troubleshooting and performance optimization I have delivered multi-node IoT systems with reliable communication, cloud data logging, and monitoring dashboards — always with a focus on practical engineering and long-term system stability. Clients value my work not only for technical delivery, but also for clear communication, ownership, and commitment to ensuring systems perform as expected in real deployment.
