Hezekiah Bosire Osero

I’m a results-driven Software Developer with 8+ years of full-stack engineering experience, focused on HMIS systems and modern web applications.

I’m skilled in PHP, JavaScript, SQL, React, and Angular, and I build and optimize backend APIs while delivering frontend modules that improve usability and stability.

In my current role at EDARP, I manage and enhance the HMIS platform: I design SQL tables, normalize structures, optimize database performance, and integrate SQL-driven data. I’ve optimized SQL to improve platform loading speed, developed new modules to improve clinic workflow efficiency, and reduced bugs while improving codebase maintainability through better structure and usability.

Previously at Conquest Capital Ltd, I developed 30+ production websites and systems, delivered landing pages, funnels, and web campaigns, and led the full software lifecycle from planning to deployment. I also integrated AI chatbots and automated search workflows, strengthening SEO and helping clients improve visibility and reach.
