Description

Embedded Software Engineer with 4+ years of experience in firmware and software development for embedded systems, industrial automation, and IoT applications. Specialized in Embedded C/C++, Python, and Rust with strong expertise in embedded Linux, RTOS, communication protocols (Modbus, CAN, UART, SPI, I2C), and real-time system design.

Experienced in building scalable software architectures, device communication layers, automation tools, backend integrations, and monitoring systems for industrial and energy applications. I focus on writing reliable, maintainable, and production-ready software with strong attention to performance, fault tolerance, and long-term system stability.

I work on projects involving firmware development, Linux-based control systems, protocol integration, cloud connectivity, Python automation, and system optimization—delivering complete solutions from architecture to deployment.

ENERGY AND UTILITIES
April 2025 - February 2026 (10 months)
Karachi, Karachi City, Sindh, Pakistan
• • Architected and delivered the full software stack for a 22 MW Battery Energy Storage System master controller (Cincoze DS-1300, Linux) — greenfield project with no prior codebase, sole developer in C, Rust, and Python.
• • Achieved sub-10 ms control loop latency on a non-RTOS Linux system by implementing a high-priority POSIX thread architecture with memory locking, enabling deterministic real-time coordination between PCS and BMS.
• • Built a non-blocking async Modbus manager (RTU/TCP, RS485) with per-device fault isolation — faulted field devices are bypassed without interrupting the main control loop, improving system resilience.
• • Designed protection state machines that operate fully offline, independent of SCADA or cloud — safety enforcement continues even during complete network loss.
• • Deployed a secondary Linux gateway (Orange Pi) integrating SNMP, MQTT, and Modbus TCP for real-time AWS cloud telemetry, remote commands, and live diagnostics across all deployed sites.

RESEARCH
May 2022 - March 2025 (2 years and 10 months)
Karachi, Karachi City, Sindh, Pakistan
• • Owned end-to-end ODU firmware for split air conditioning systems across STM32, NXP (Kinetis), Renesas, and ESP32 — same codebase deployed across 4 MCU families via a hardware abstraction layer, cutting porting time for each new platform.
• • Redesigned inverter control algorithms from scratch, replacing a single-product legacy implementation with a scalable architecture that supported multiple compressor variants and improved energy efficiency across production SKUs.
• • Wrote all peripheral drivers from scratch: ADC (NTC thermistors, current sensors, pressure), UART (IDU comms), SPI (flash), I2C, PWM (motor control), IR (remote receiver with timer input capture), stepper motor — no vendor middleware dependencies.
• • Implemented FreeRTOS task architecture with hardware watchdog integration and a hierarchical fault system including graceful degradation modes — fan-only operation if compressor protection triggers, preventing hard failures in the field.
• • Led hardware-software co-debugging at PCB level using oscilloscopes and logic analyzers; resolved EMC compliance failures and ensured stable field performance before each production release.
• • Released multiple mass-production SKUs in collaboration with R&D teams in China and Turkey, meeting ISO safety and quality sign-off requirements on schedule.

Embedded Software Engineer
January 2023 - December 2024 (1 year and 11 months)
Groningen, Netherlands
Held concurrently with Dawlance role.
• • Led firmware development for autonomous drone docking stations on ESP32 (C/C++, Python) — covering system architecture, hardware selection, and full mission cycle firmware (takeoff, navigation, docking, charging).
• • Implemented CAN, UART, Bluetooth, and Wi-Fi drivers for real-time coordination between drones, docking hardware, and ground control systems.
• • Designed a flex PCB-based wireless charging system and built a Python-based SDK with Dockerized control services, enabling third-party drone integration and remote telemetry management.
