Kasidit Yusuf - telecom software engineer, off-grid solar and algae-farming hobbyist

I’m a wireless-protocol software engineer from Thailand - developing wireless-protocol software since 2004 and commercial mobile-network test and measurement software since 2006.
Telecom software work history
- 2006 - Nokia Symbian S60 (Symbian C++). My start in commercial mobile software: Sittiphol Phanvilai kindly recommended me to his colleagues at Zenith Core - Nuttapon Boonpinon, Sorawish Dhanapanichkul and Nopphorn Danchainam - for their mobile-operator app development projects.
- AZENQOS - co-founder and main developer. The Zenith Core team later moved into Freewill FX (Freewill Solutions group), where, with guidance from Dr. Veera Veerakool, David B. Aldridge and Orachat Rakphongphairoj, I co-founded AZENQOS with Nuttapon, Sorawish and Nopphorn and was its main developer - a mobile-network test tool, first on Symbian OS 9 and then on Android. A bit later Songkran Jarusirisawad and Don Plooksawasdi joined Freewill FX and drove AZENQOS forward in Thailand, India, Hong Kong and beyond. Through this work I gained deep hands-on experience with mobile-network test tools, from low-level phone internals to server-side data processing.
- Sigma-AQ under Meritech. AZENQOS was acquired by Meritech (Japan). Guided by Harish Sachdeva, Indrajeet (Teddy) Khater and Meritech’s engineering teams in Japan and India, the product evolved into Sigma-AQ under Meritech Solutions; I continue with it at Meritech, where I still develop it today and try to pass on what I’ve learned about telecom software and data processing to the next generation of engineers.
Open-source projects: https://github.com/ykasidit
Tools and languages. GNU Emacs on Ubuntu MATE; Python for data, Go for web APIs, Rust for low-level - why not C++ or OOP.
Current hobbies - a lifelong appreciation of space, physics and science that started in childhood, now hands-on: DIY off-grid solar and batteries - enough to run air conditioning overnight, water pumps, drills and a welder - and, powered by it, a DIY seawater intake and some algae-farming experiments.
I started ClearEvo.com in early 2005 as a home for the software I was building on my own time - the Nokia Symbian and J2ME days - and the official pages and blog for my open-source projects. When my brother Adeeb needed to expand his medical device wholesale business, I was more than happy to share the website and the name - hence CLEAREVO GROUP CO., LTD.
Highlights:
- One of the world’s 29 winners of Symbian Software’s global “Because of the Code” competition, 2007 - yes, I loved the Nokia E61 and the Symbian notebook bag they kindly shipped all the way from the UK to Thailand, along with the Symbian OS Internals book and the winner’s certificate signed by David Wood.
- A winner of Sun Microsystems’ Thailand Java Contest 2003 (“Personal Applications” category) - the J2ME “Bangkok Bus Pathfinder”, which ran on the Siemens SL45i, developed with Anon Sutthichairatana.
- BSc in Computer Science, Kasetsart University - degree project: a C++ implementation of the Bluetooth L2CAP, SDP, RFCOMM and OBEX protocols (source on GitHub, archived).
