Olatunde Success reflects on moving from senior full-stack engineer to CEO of SAW Technologies Limited: what carries over from engineering leadership, what had to change, and how shipping Dbrij, Cirva, and Resikonet reshaped his definition of done.
I spent eight years shipping software for other people’s companies: fintech rails, legal-tech platforms, marketplaces, core banking. Founding SAW Technologies Limited and building Dbrij, Cirva, and Resikonet under one roof changed my job description completely, and left more of my engineering instincts intact than I expected.
What transferred directly
Systems thinking: a company is a distributed system. Unclear interfaces between people fail exactly like unclear interfaces between services.
Writing things down: the RFC habit became decision memos; the audit-log habit became board-ready records.
Security as posture: the same paranoia that puts idempotency keys on payment endpoints now reviews vendor contracts and data processing agreements.
What had to change
As an engineer, done meant merged, tested, and deployed. As a CEO, nothing is ever that clean. Done means a customer renewed, a regulator satisfied, a hire ramped, cash in the bank. The feedback loops are slower and noisier, and you cannot write a test for them. The discipline I lean on is the same one that made me a decent engineer: make the state visible, make the transitions explicit, and never let two sources of truth drift.
Staying technical on purpose
I still architect and still review code. Not because the team needs me to, but because our products live or die on technical trust: escrow engines, encrypted identity data, banking integrations. A CEO who can read the diff keeps the company honest about what is actually shipped versus what is promised. In a market where credibility is the moat, that is not a luxury. It is the job.
