Technical Project Manager & Tech Entrepreneur
My tech career began in frontend development and software engineering before I discovered my true passion for project management. Throughout my career, I have managed a variety of national and international projects across FinTech, EdTech, and enterprise software. I specialise in bridging the gap between complex technical execution and strategic business objectives, having successfully led large-scale international projects across the UK, USA, Austria, Italy, UAE, Malaysia and East Africa. Currently, I am a technical project manager at Arbree Limited, and I also run Technonix, a startup dedicated to building practical technical solutions for real-world problems.
Beyond tech, I am an active human rights advocate who believes strongly in giving back to society. On a personal level, I am an avid traveller and tech enthusiast who loves thrilling adventures, watching movies, and simply hanging out with friends.
