Olusola Karokatose

Olusola Karokatose is a visionary software engineer and entrepreneur who transforms challenges into scalable, efficient solutions. A self-taught coder since 2013, he discovered programming while studying Zoology and quickly developed a passion for automation—creating an image-sorting algorithm that cut manual processing time from days to minutes. That breakthrough ignited a career dedicated to engineering excellence and innovation.

After university, Olusola joined a research agency as a data analyst, where he architected Python and Jupyter-based pipelines that slashed data turnaround by over 80%. He was then recruited by Paystack (acquired by Stripe), advancing to Technical Lead and spearheading backend services that support millions of transactions. His leadership established robust DevOps practices, accelerating deployment velocity and bolstering system reliability.

In 2025, Olusola founded Varsi, an HR-tech startup unifying Learning Management and Performance Management in a single intuitive platform. Under his guidance, Varsi has conducted over 1,200 cold outreach calls, scheduled 28 product demos, and secured pilots with major clients—including Paystack—while gaining traction across sales, construction, and consulting verticals. His vision emphasizes seamless integrations (Slack, SSO, analytics) and flexible pricing models that enable fast-moving teams to onboard, train, and measure growth effortlessly.

Fluent in JavaScript/TypeScript, PHP, Python, and Go, Olusola thrives on turning complex requirements into elegant, maintainable code. He welcomes strategic partnerships—whether with enterprise HR systems, content providers, or technology integrators—to expand Varsi’s ecosystem and drive shared success. Based in Canada, he is passionate about driving digital transformation, mentoring the next generation of engineers, and continually pushing the frontier of HR technology through automation, continuous learning, and user-centric design.
