Testimonials

Glenn P. Founder, StuffInABox Solutions · 2011–2013
"Asad led our engineering team and built a comprehensive CRM and IMS from scratch that completely transformed how we operated. The HughesNet integration he implemented eliminated manual processing entirely and cut our operational delays by 40%. What impressed me most was his ability to train our team and hand off a complex system in a way that was actually maintainable. Three years later, he left us with tools that still work beautifully."
Damian M. Founder, VDYO · 2014–2016
"Asad was our lead engineer for the VDYO video platform that powered streaming for AACTA (Australian Academy Awards) and other major media companies. He built our multi-tenant architecture with proper RBAC/ABAC security, implemented HLS streaming with DRM, and delivered analytics features like Video Heat Maps that our clients loved. He handled the complexity of video processing at scale so we could focus on growing the business."
Azat Ahmedov Senior Developer at ZeniMax Media · 2019–2022
"Asaduzzaman is a professional developer and an honest, good person. We worked on the same project for 3 years. He set up our entire backend infrastructure using Go and microservices, and never shied away from any challenge. His code is clean, professional, and scales well. I would definitely recommend him."
