I’m a software engineer and technical writer who helps startups grow. I build full-stack products, and I write engaging tutorials and articles that market your product to developers and turn readers into users. My work runs on freeCodeCamp and DEV, and I’ve worked with software companies including Zernio, Stream, Novu and OpenMRS.

🚀 Open to work with startups: technical content, developer marketing and product engineering. Let’s talk →

On the side, I research computer vision (detection, segmentation and multimodal models) and I’m open to graduate research opportunities. I graduated top of my class in Computer Science with First Class Honours (4.8/5).
