Systems Development & Innovation

Building robust, scalable systems that drive business growth
Hi, I'm Walter Duri, founder of ConAction. I engineer scalable platforms, modernize legacy systems, and turn complex challenges into elegant, high-impact solutions — with 10+ years of battle-tested expertise.




"When we started Dravental, we needed more than just an app—we needed someone who understood the unique challenges of car hire in Zimbabwe. Walter delivered an end-to-end solution that handles everything from booking to payment verification. His engineering mindset meant he thought through edge cases I hadn't even considered, like network resilience in areas with poor connectivity. The app has transformed how we operate, and our customers love the seamless experience. I highly recommend him for any serious mobile project."
"Walter built GoTicky from the ground up, and what impressed me most was his ability to translate our vision for Zimbabwe's entertainment scene into a functional, beautiful product. He understood that events here aren't just transactions—they're experiences. The ticket validation system, the real-time notifications, the smooth payment flows—everything works exactly how our event organizers need it. He's not just a developer; he's a product thinker who genuinely cares about the end user."
"The property market in Zimbabwe has its own complexities, and Walter navigated them brilliantly. From handling different listing types to managing broker relationships and payment flows, he built RentOut with a deep understanding of how real estate actually works here. His background in operations management really shows—everything is systematic, well-documented, and scalable. We've already seen an uptick in property inquiries since launching."
"As a medical facility serving communities across Zimbabwe, we've seen firsthand how healthcare access challenges affect real people. Walter's QuickMed platform addresses problems we've grappled with for years—patients missing appointments due to poor communication, prescription errors from manual processes, and the administrative burden that takes nurses away from patient care. The financial impact is significant too: reduced no-shows mean better resource utilization, and streamlined billing cuts our administrative costs by nearly 30%. But more than the numbers, this app will genuinely change lives. A patient in rural Mashonaland can now book a specialist consultation in Harare without traveling twice. An elderly diabetic can get medication reminders and refill prescriptions without leaving home. This is the kind of digital health infrastructure Zimbabwe has needed, and Walter built it with deep understanding of our local context—from network resilience in low-connectivity areas to mobile money integration that works with EcoCash and OneMoney. Exceptional engineering with real human impact."
