I build backend systems that businesses actually run on. From database schema to live server — Laravel, PHP, PostgreSQL, React, Next.js, Node.js, Python — deployed and maintained without handing off.

About
Building systems businesses depend on
Over four years I have shipped production systems across fintech, enterprise SaaS, hospitality, and the public sector. The common thread is ownership — I do not hand things off at the API layer. I provision the server, configure the reverse proxy, set up the CI/CD pipeline, and make sure what I build works in production under real conditions.
My primary stack is Laravel and PHP on the backend, with React and Next.js on the frontend. I am as comfortable writing a complex Eloquent query with proper indexing as I am building a filterable React interface that consumes it.
Currently working remotely from Lagos with a UK-based team. Four years of distributed async work — no adjustment needed.
Backend Architecture
SSO across 20+ apps on a single auth layer, multi-tenant SaaS, payment systems, and KYC infrastructure built for scale.
Full Deployment
Nginx, Apache, CI/CD pipelines, SSL, PM2, Supervisor — I own the path from git push to live server.
Security First
OWASP, OAuth 2.0, JWT, RBAC, HMAC signing, and audit logging aligned to data protection compliance.
Experience
Work history
Full-Stack Engineer
July 2025 – Present- Build and maintain Laravel backend systems for client web products — API design, service layer, and database schema on a remote-first async team.
- Provision and manage production server environments — configuring Nginx reverse proxies, SSL certificates, CI/CD pipelines, and deployment workflows on client VPS infrastructure.
- Implement authentication flows, role-based access control, and API contracts via Postman consumed by frontend clients.
- Optimise database performance through indexing strategies and Redis caching — diagnosing bottlenecks with Laravel Telescope before optimising.
Full-Stack Engineer
Sept. 2023 – Present- Architect and maintain complete backend infrastructure for a travel agency booking platform — payment gateway integration, booking lifecycle management, and user dashboard APIs serving 500+ active bookings monthly.
- Architect and maintain an enterprise SSO platform spanning 20+ internal applications — centralised user management, JWT session flows, RBAC routing, and HMAC inter-service signing — reducing authentication overhead by over 40%.
- Maintain and extend existing Node.js application codebases — implementing feature updates, resolving bugs, and ensuring compatibility across integrated services.
- Maintain a multi-tenant hotel management SaaS — Laravel backend with global tenant scoping, reservation and inventory engine, revenue dashboards, and React admin interfaces with live Chart.js analytics.
- Maintain a fintech wallet system — Paystack integration, wallet funding, peer transfers, virtual account management, utility payments, and an append-only transaction ledger in kobo with lockForUpdate() preventing concurrent double-spend.
- Designed a dual-mode vehicle service interface (photo-upload fault diagnosis vs direct quote flow) backed by a nine-factor specialist matching engine using Http::pool() for parallel API scoring.
- Maintain a KYC/identity verification microservice consumed across the firm's product suite — KYCProviderInterface abstraction, encrypted credential storage, NDPR-aligned audit logging.
- Manage full deployment lifecycle — Nginx configuration on Contabo VPS, CI/CD pipeline setup, Supervisor for queue workers, and zero-downtime deployments across all platform stacks.
- Improved application performance by ~30% through composite database indexing, Redis tag-based cache invalidation, and offloading expensive operations to Horizon-managed background queues.
Server Administrator & Web Developer
Feb. 2024 – Nov. 2024- Managed web hosting environments on shared infrastructure — configuring domain DNS, virtual hosts, and server blocks for PHP and JavaScript application hosting.
- Deployed and maintained Laravel and React applications to production — environment configuration, dependency management, and application restart strategies.
- Configured SSL/TLS certificates across multiple client domains, reducing manual overhead and ensuring HTTPS compliance site-wide.
- Set up file-based backup schedules and uptime monitoring for business-critical client applications.
Junior Web Developer
Oct. 2021 – Jan. 2023- Built client websites and web applications using vanilla PHP, HTML, CSS, and JavaScript — first professional exposure to non-WordPress, code-first development.
- Introduced to Laravel and React through internal projects, developing foundational understanding of MVC architecture and component-based UI patterns.
- Delivered and deployed two Python/Django projects to production — backend logic, templating, and database integration under senior developer guidance.
- Documented project requirements and maintained technical notes for client-facing web components.
