Embedded Software Engineer building real-time hardware–software solutions.
I’m a final-year Electronics & Communication Engineering student at Jamia Hamdard, New Delhi, holding a cummulative CGPA of 9.12. My work spans both hardware and software domains including embedded systems software and firmware development, circuit designing & prototyping, web development and sensor interfacing.
I focus on building end-to-end solutions involving bare-metal programming, IoT pipelines, real-time data processing, and full-stack integration. I work across the stack: communication protocols, cloud synchronization, embedded firmware development, PCB prototyping, ADC calibration, backend systems and interactive web interfaces.
A two-node wireless water tank level monitor built on the RP2040 in bare-metal C- no framework, just registers, PIO, and a clock. The transmitter fires the AJ-SR04M ultrasonic sensor with a custom PIO state machine that captures the echo width, using a hardware-generated trigger pulse and timeout, then ships each reading over an E32 433 MHz LoRa module on UART with M0/M1/AUX mode control.
The two ends talk over a framed packet protocol I designed: a header, status byte, 16-bit distance, XOR checksum, and trailer, taken apart on the receiver by a byte-wise state-machine parser. The receiver's second core is brought up by hand through the RP2040's SIO FIFO handshake : Core 0 does nothing but parse incoming frames and pass measurements along, while Core 1 owns the ILI9341 level gauge and the buzzer alarm. A 64-bit timer-based link-loss watchdog flips the display to "TX OFFLINE" whenever no valid frame has arrived for 15 seconds making sure the transmitter is alive or not. I also designed and routed single-layer PCBs in Altium Designer for both nodes, and powered each one from a rechargeable Li-ion battery so the pair runs standalone and portable.
SD Card FAT32 File Explorer & Media Viewer for ILI9341 Display :
Built a bare-metal SD card storage stack and display pipeline on the RP2040 using register-level SPI programming, with no vendor SDK or HAL. Wrote the SD SPI-mode initialisation sequence (CMD0, CMD8, ACMD41, CMD58, CMD16) with response polling and timeout handling for SDHC cards, then read 512-byte blocks with CMD17. Parsed the MBR partition table and FAT32 BPB by hand and traversed the FAT cluster chain to walk directory entries, match 8.3 filenames, and reassemble multi-block files from the card.
On the display side, brought up the ILI9341 TFT with a full init table and configured MADCTL and RGB565 for correct orientation and colour order. The RP2040 has no JPEG decoder, so I designed a PC-side tool that pre-converts a JPEG into a headerless 240 x 320 RGB565 blob and streamed it straight to the panel through its address window. The next stage is replacing that workaround with a from-scratch JPEG decoder on the Pico itself — entropy decoding, dequantisation and IDCT — so the card can hold real .jpg files and the device decodes them on the fly.
Extended the path with a DMA-backed streaming engine: a double-buffered DMA channel driven by the SPI TX DREQ, ping-ponging buffers so each cluster read goes straight to the peripheral while the next is fetched. On top of that sits a UI — a card-info screen, a scrollable file browser using push buttons reading the directory tree live, and an image viewer with a render progress bar.
Wall-powered IoT health station on ESP32 measuring heart rate, SpO₂ & body temperature via MAX30102 and DS18B20. Custom BPM peak-detection (EMA) and Maxim's ratio-of-ratios SpO₂ algorithm over 100-sample rolling buffer.
Non-blocking firmware with millis()-based timers, OLED auto-rotate, MQTT/TLS cloud sync to Arduino IoT Cloud, and hand-soldered 6×4 perfboard with regulated 12V→5V→3.3V power chain (LM2596 + AMS1117). Project showcase site deployed via GitHub Pages.
Smart information dashboard on Raspberry Pi displaying live time/date, real-time weather, top news headlines, motivational quotes, and an editable to-do list. Developed during research internship at IIIT Guwahati.
Integrated OpenWeatherMap and NewsAPI for dynamic content with JSON-based config. Explored secure IoT protocols, embedded Linux, and API-based data pipelines on resource-constrained hardware.
A responsive personal portfolio website showcasing my projects, technical skills, and development journey with a Formspree-integrated contact form for direct user communication. Built using HTML, CSS, and JavaScript with a clean, modular structure, it includes dedicated blog/posts pages for technical write-ups, customizable light and dark themes with a system mode, and navigation designed for desktop, tablet, and mobile screens. Deployed on GitHub Pages for easy access and sharing.
Working on autonomous UAV systems, embedded electronics, and flight controller integration as part of my summer internship at IIT Jammu with Dr. Sudhakar Modem. Gaining hands-on experience in drone development, hardware-software integration, and practical implementation of UAV technologies.
Contributed to embedded software development by working with microcontrollers, embedded systems, and hardware-software integration. Also worked on web development projects, building practical skills in firmware development, debugging, and full-stack application development.
Built "Smart Display System" — a Raspberry Pi-based IoT display with real-time weather, news, quotes, and to-do integration. Explored secure IoT protocols, embedded Linux, Python scripting, and cloud connectivity on resource-constrained hardware.
Serving as the Head Coordinator, I led recruitment initiatives with professionalism and teamwork : managing operations, guiding the team, and fostering strong campus-industry relations through effective student coordination and corporate engagement.
