01Introduction

About me

I like hard problems with real-world consequences.

Hi, I'm Aryan — part engineer, part storyteller, and part “let's see if this works” experimenter. I've spent the last few years building everything from Bluetooth gadgets to tiny ion engines (yes, they work… mostly), and explaining them in a way that doesn't require a PhD or three cups of coffee.

When I'm not writing technical guides for Hackster.io or Arduino, you'll probably find me tinkering with Java code, designing user interfaces, or running a club meeting that somehow turns into a brainstorm about rockets. I love mixing tech skills (UI/UX design, embedded systems, Java development) with people skills (leadership, outreach, making complex things simple).

I like solving problems, teaching others, and occasionally making robots do my bidding. If it beeps, blinks, or launches into the sky, I'm interested.

Things I’ve made.

01 / Remote Telemetry

V-TEL
Telemetry Board

A 4-layer ESP32 telemetry PCB for RC planes, selected by PCBWay engineers for full sponsorship.

Designed in KiCad to capture camera feed, IMU, GPS, and environmental data to SD card. Interrupt-driven C/C++ firmware eliminated sampling aliasing, while a Python engine reconstructed 3D flight paths from sensor logs.

02 / Hiker Safety

SIGMA
Wearable

Hiker assistance wearable device. 1st Place, IEEE Tech-A-Thon.

Engineered an end-to-end RF mesh network for hiker SOS signaling in rugged terrain. Reduced packet loss by 50% with parity checks, extended range 10× with a 20 dBm amplifier, and built a companion website for live first-responder monitoring.

03 / Low-level computing

DOOM on an
ARM MCU

Getting an unlikely classic to run on a very small computer.

A deep dive into memory limits, display drivers, and low-level optimization. With a 99% memory utilization and 2 GB of additional sounds on an SD card, the result is a playful proof of what careful systems work can make possible.

04 / Power electronics

Buck
Converter

A custom DC-DC power stage, from simulation through bench validation.

I simulated a synchronous dual-MOSFET topology against a diode-based design and chose it for the 10% efficiency gain, landing on 5 A continuous at over 90% efficiency. I built the feedback loop around a TLV2372 error amplifier for stable regulation, then laid out the PCB myself — adding thermal relief vias and sizing the inductor and output capacitor to control switching ripple.
