Hire the Best VHDL Specialists
in Pakistan

I'm an FPGA and embedded engineer who takes digital hardware from spec to working bring-up on real boards, architecture, RTL, verification, synthesis, timing closure, and on-board validation. On the FPGA side I write production-grade Verilog/SystemVerilog, build and debug designs in Vivado and Vitis (also ISE and Quartus when a project needs them), and target Xilinx Zynq-7000, Zynq UltraScale+, Artix/Kintex-7, and Lattice parts. Day-to-day work: clean RTL (FSMs, pipelining, CDC), AXI4/AXI-Lite/AXI-Stream SoC integration, custom IP, and constraint/timing closure on designs that have to actually meet Fmax, not just simulate. Verification is part of the job, not an afterthought, SystemVerilog testbenches, functional and code coverage, and assertions. I simulate in ModelSim/QuestaSim, Verilator, and Icarus, and debug on hardware with ILA, logic analyzer, scope, and JTAG. I go deep on RISC-V: custom RV cores, ISA extensions, and emulators, including instruction-set modification and syscall/binary remapping at the userspace level. On the embedded side I write C/C++ for microcontrollers and Linux, work with the GCC/LLVM toolchain, and handle interfaces like UART, SPI, I2C, DMA, PCIe, and Ethernet. If you have hardware or low-level software problems or need a new solution, send the spec and I'll reply with a clear scope and timeline.

50+ hardware and embedded systems projects delivered, from concept through manufacturing. Full project lifecycle ownership: requirements → schematic → PCB layout → firmware → prototyping → testing → DFM/production handoff. Projects spanning industrial electronics, IoT devices, RF systems, wearables, and battery-powered products. I design and build hardware products that survive real-world contact — not just designs that work in simulation. For 6+ years, I've taken products from a blank schematic to manufactured, field-deployed hardware: industrial electronics, IoT devices, RF systems, and embedded platforms used in real industrial and consumer environments. I work across the full stack — system architecture, PCB layout, firmware, prototyping, and DFM — so you get one engineer who understands how a firmware design decision affects the PCB, and vice versa. If you need someone who can own a hardware product end-to-end, or step into a specific phase (schematic review, firmware bring-up, RF tuning, manufacturing prep), I can help. WHERE I ADD THE MOST VALUE Custom PCB design, 2–12 layers, including high-speed digital and RF layouts EMI/EMC-aware design and Design for Manufacturing (DFM) Embedded firmware in C/C++ for ESP32, STM32, nRF52/nRF53, RP2040, and ARM Cortex-M platforms IoT connectivity: Wi-Fi, BLE, LoRa, GSM/LTE, GPS/GNSS, cloud-connected devices Industrial communication: UART, SPI, I²C, RS485, Modbus, CAN Bus Power electronics: battery management systems (BMS), DC-DC converters, SOC/SOH estimation, industrial power monitoring Prototype-to-production support, including BOM creation and manufacturing handoff RECENT WORK Industrial gas metering system (EVC V5) — redesigned the hardware architecture with RS485, CAN Bus, and Modbus communication, built to meet EMI/ESD protection and hazardous-environment requirements. Ground Penetrating Radar — designed a 100–900 MHz subsurface sensing system built around a high-efficiency Class-E RF power amplifier and custom embedded electronics. EEG smart glasses — developed wearable electronics for brainwave acquisition, signal conditioning, embedded processing, and wireless transmission. Dual-MCU wireless audio platform — low-power architecture combining nRF5340 and ESP32-S3, with BLE, Wi-Fi, secure storage, and advanced power management. Energy monitoring & battery management platform — multi-source monitoring across AC power, solar generation, and battery storage, with SOC/SOH estimation, GSM connectivity, Ethernet, and remote monitoring. High-power RF amplifier — 100 MHz Class-E design delivering up to 1 kW output. Multiple ESP32-based industrial and consumer products — automation, environmental monitoring, sensing, and data acquisition. Aero-Guide robot — autonomous, AI-assisted navigation platform, finalist in a national engineering competition. WHAT YOU GET WORKING WITH ME Clear technical communication from day one — I'll tell you early if something won't scale, won't pass EMC, or won't be manufacturable, rather than letting you find out after fabrication. Deliverables built for handoff: schematics, PCB layouts, Gerbers, BOMs, manufacturing files, firmware, and documentation — organized so another engineer (or your future self) can pick them up. Fast, practical problem-solving when prototypes don't behave as expected. A focus on shipping reliable, buildable hardware — not just a working bench demo. Outside of engineering, I spend time mountain trekking, with expeditions to several major peaks in Pakistan, including base camps of multiple 8,000m mountains. It's where I keep my planning and problem-solving instincts sharp under pressure — skills that translate directly into debugging hardware at 2 am before a deadline. If you have a hardware or firmware challenge — from a rough concept to a stalled prototype that needs fixing — I'd be glad to take a look and tell you honestly what it'll take to get it done right.
