Damilare Ogunsiji

Nigerian Software Engineer • Founder • CTO

I build fintech infrastructure, SaaS platforms, automation and AI products, and secure backend systems for African markets, with production reliability as a core requirement.

Build systems that survive real users, not just demos.

Fintech Infrastructure SaaS Builder AI and Automation Security Aware

Profile

I'm a Nigerian software engineer, founder, CTO, and technology entrepreneur with 8+ years of experience. I hold a B.Sc. in Mathematics, have founded multiple technology ventures, and serve as CEO and CTO across fintech and SaaS businesses.

My expertise spans fintech infrastructure, payment systems, SaaS engineering, AI and automation, secure backend architecture, and product development. I build scalable, production-ready systems that solve operational problems, support dependable daily use, and contribute to long-term product and infrastructure development.

What I Build

  • Fintech infrastructure: Airtime, data, and bill payment systems; payment collection platforms; fintech APIs and vending infrastructure; transaction processing systems.
  • SaaS platforms: Multi-tenant products, business automation systems, internal operational tools, and subscription-based platforms.
  • Automation and AI: Workflow automation, AI-assisted business processes, productivity and operational tooling, and intelligent software integrations.

Security and Reliability

Security is part of my engineering process, not an afterthought. I design backend systems for web and mobile applications with:

  • API and application authentication and authorization, including JWT and token-based security
  • Secure Laravel architecture, OWASP security principles, and input validation
  • Abuse prevention, rate limiting, and monitoring
  • Secure deployment architectures and pipelines, production reliability, and observability

Technology Stack

PHP, Laravel, MySQL, PostgreSQL, Redis, and Go JavaScript, Alpine.js, and Tailwind CSS Docker, Linux, Git, and GitHub

  • Backend and data: PHP, Laravel, Python, Go, REST APIs, Laravel Livewire, MySQL, PostgreSQL, Redis
  • Frontend: JavaScript, Alpine.js, Tailwind CSS
  • Mobile: NativePHP
  • Infrastructure and delivery: Docker, Linux servers, Git, GitHub, CI/CD pipelines
  • Workflow: AI-assisted development workflows

Current Priorities

  • Scaling fintech infrastructure systems
  • Building AI-powered business products
  • Expanding SaaS automation platforms
  • Strengthening system security and reliability
  • Designing APIs for real-world usage
  • Building technology companies with long-term impact

Engineering Principles

  • Simplicity over unnecessary complexity
  • Security by design
  • Sustainable and scalable architecture
  • Fast execution without sacrificing quality
  • Solving real operational problems
  • Continuous improvement through iteration

Interests

Outside engineering, I explore artificial intelligence, business strategy, financial technology, product development, systems thinking, and emerging technologies. I am particularly interested in building technology that improves access, efficiency, and opportunities across African markets.
