Where I've worked.

Building and deploying full-stack and backend-focused projects for clients across ed-tech, vocational training, and tourism industries.

• —Built and deployed GraceRN, a full-stack ed-tech exam preparation platform now serving 500+ daily active users in production
• —Developed FEVOTI's web platform for a vocational training institute in Liberia, consolidating 8+ programmes into a single accessible site
• —Built Aruba Clear Kayak, a TripAdvisor-integrated booking platform that went live and began generating real bookings within weeks of launch
• —Applied technical SEO across all projects — schema markup, canonical URLs, sitemap generation, semantic HTML, and page speed optimisations

Owned end-to-end backend architecture for real-time multiplayer games, focusing on performance, reliability, and service modularity.

• —Owned end-to-end backend architecture for real-time multiplayer games using Nakama, designing match lifecycle logic, RPCs, and player session management that scaled to 1000+ concurrent users via horizontal scaling and load balancing
• —Led the migration from a monolithic codebase to a microservices architecture, cutting deployment cycle time by 40% and enabling independent scaling of high-traffic services
• —Designed and optimised REST APIs serving concurrent mobile users, reducing average API response time by 35% through query optimisation, Redis caching, and connection pooling
• —Engineered secure payment integrations (Stripe, Khalti) with webhook validation and idempotency checks, reducing failed transactions by over 90%
• —Established Docker-based containerisation and zero-downtime deployment pipelines with automated rollback, reducing production incidents by 60%
• —Defined API contracts and technical standards in collaboration with frontend and mobile teams across Agile sprints, cutting integration bugs by 50%

Took technical ownership of backend feature development and testing across 3 production applications with active user bases.

• —Took technical ownership of backend feature development using Node.js and TypeScript across 3 production applications with active user bases
• —Designed, documented, and versioned REST APIs using Swagger, reducing frontend–backend integration issues by 40% and accelerating onboarding for new team members
• —Built a comprehensive automated test suite (unit, integration, regression) using Jest, increasing code coverage from under 20% to 75%
• —Drove CI/CD improvements by integrating automated test pipelines, reducing regression-related hotfixes by 30% across quarterly release cycles
• —Managed production deployments across VPS environments and owned AWS (S3, IAM) configuration for storage, access control, and environment security
• —Mentored junior developers through structured code reviews, establishing best practices that improved overall codebase maintainability

Worked on backend systems for real-time and IoT-based applications, contributing to performance and feature development.

• —Delivered backend components for real-time and IoT-based systems using MQTT and WebSockets within the first month of joining
• —Implemented role-based access control (RBAC), CRUD operations, and Redis caching strategies, reducing average API latency by 25%
• —Contributed to system-wide optimisation and refactoring efforts, working alongside senior engineers in an Agile environment
