The Engineer Behind Alchemy Solutions

Tehsinudin Wazir — Founder of Alchemy Solutions

Tehsinudin Wazir

Founder & Lead Engineer

Tehsin graduated in Electrical Engineering from the University of Engineering & Technology (UET) Taxila in 2018, and has spent every year since designing embedded and IoT products for clients around the world. What began as freelance firmware work grew into Alchemy Solutions — a product house that takes ideas from schematic to shipped app, all under one roof.

Every project on this site was engineered hands-on — and every five-star review was earned one delivery at a time.

★★★★★

"Tehsin delivered solid ESP32-S3 firmware for our IoT product on schedule. Code is clean and modular, with well-thought-out separation of concerns across the manager classes. He covered the full scope including captive portal provisioning, offline queue, battery monitoring, per-device auth, and reboot recovery. Documentation is thorough which makes the firmware reproducible without him. Professional communication. Recommended for IoT firmware work and would collaborate again."
