About Blen

I'm a full-stack software engineer with a strong foundation in AI, cybersecurity, and backend systems. I've built and led scalable solutions using technologies like React, Node.js, Django, Go, and PostgreSQL—spanning fintech, ed-tech, and internal tools.

As Head of Academy for Remote Education at A2SV, I managed a team of 20 to support 100+ students across 20 countries, improving learning experiences and operational efficiency. I also contributed to product strategy and development for Dime, a remittance platform serving the African diaspora.

My work blends deep technical skills with leadership, education, and social impact. I'm passionate about building systems that are secure, user-centered, and scalable.
