Semeton Balogun

Backend and systems engineer, moving into solutions architecture.

Semeton Balogun

I turn business goals into systems that hold up in production: tenant isolation for banks and enterprise SaaS, deployments inside bank networks, and data that stays correct across offline devices. I'm CTO at Lawyering, and work at Seamless Technologies and on contract with eGov Foundation.

I came to software from nursing, after qualifying as a registered nurse at the University of Lagos. My background →

What I work on

Banks & enterprise SaaS

Multi-tenant platforms

Goal: Sell one product to many organisations, each with its own branding, rules and infrastructure, without keeping a codebase per client.

As CTO of Lawyering I'm building a platform where law firms and individual practitioners each get an isolated workspace for their staff and clients. At Zercom I merged per-client copies of an LMS into Tangerine365: one codebase, tenants by subdomain or by ID. At Seamless I work on tenant isolation for a multi-tenant HR suite.

Solutions architecture

Deployment and infrastructure design

Goal: Run each system on infrastructure that fits its budget, its compliance rules and its risk.

For client deployments I write the sizing, server requirements and deployment architecture, including First Bank's three-tier on-premise build. For Zercom's own internal tools, staging and UAT, I moved separate DigitalOcean droplets onto one server running CyberPanel and LiteSpeed, configured for wildcard subdomains, and cut that hosting bill by about 85%.

National health campaigns

Offline-first data systems

Goal: Field workers in malaria campaigns get credited and paid for the days they actually worked, even when their phones sync late.

On contract with eGov Foundation I support DIGIT HCM across Abuja, Bauchi, Taraba and Borno. I traced worker lockouts to activities being dated at sync time instead of creation time, and I'm sizing infrastructure and support staffing for a 2027–29 programme across 11 states (~27M people).

How I work

Guardrails for AI coding agents

Goal: Get the speed of AI coding agents on production codebases without losing control of what they change.

I work agent-first. agent-contract, my npm CLI, checks every write an agent attempts against the repository's rules and blocks anything outside the task's scope before it lands. I'm also researching repository memory: how a decision log stays true and reaches the agent at the right moment, behind a write gate that humans control. It's the subject of my talk for PHP Talks Lagos.
