Backend Developer

Taskingdom

Backend developer on a task-based gaming platform where users complete tasks and jobs to earn real-money rewards, with four distinct user roles and strict permission boundaries.

• ›Built permission and role system supporting four distinct user types — Regular users complete tasks, VIP users access higher-reward tasks, Business accounts create tasks and jobs, and Influencers take jobs to promote businesses.
• ›Designed abuse prevention logic using a hybrid storage strategy — task completion records stored in Redis with TTL matching task expiry for short-lived tasks, and a join table for longer or non-expiring tasks, preventing users from farming rewards across task resets.
• ›Built webhook integration linking third-party game outcomes to internal user accounts, triggering reward payouts when game conditions were met.
• ›Co-designed core database models including user, task, reward, and role schemas to support the platform's task execution and payout flow.
• ›Implemented Google OAuth authentication alongside token-based access control for API security.
• ›Moved heavy operations to Celery background workers backed by Redis, improving responsiveness of user-facing endpoints.
• ›Built a custom image storage and serving system, reducing bandwidth usage and decoupling image delivery from application logic.
• ›Worked closely with frontend engineers to align APIs with real product usage and evolving requirements.

Backend Engineer

Meerge Africa

Backend engineer at a startup building a multi-service food commerce platform connecting vendors, suppliers, and delivery operations across independent microservices.

• ›Designed and led development of the Supplier service from scratch — the primary service I owned, supporting 500+ suppliers with an average of 50 products each during pilot operations.
• ›Built supplier lifecycle management with four explicit states (pending, approved, rejected, suspended), full audit logging on every transition, and admin tooling for operations teams to manage the pipeline.
• ›Designed secure service-to-service communication using JWT tokens scoped to specific service identities, preventing cross-service privilege escalation.
• ›Refactored bare except blocks and swallowed exceptions into structured error-handling flows with consistent response formats and full logging — significantly reducing silent failures and making issues traceable.
• ›Introduced Redis caching with explicit invalidation on mutation events, reducing repeated database queries across high-traffic endpoints.
• ›Co-developed backend logic for the Delivery service including order creation, assignment workflows, and order status polling.
• ›Reviewed pull requests across all three backend services — Supplier, Delivery, and Kitchens — helping maintain consistency and code quality across the platform.
• ›Stepped in as acting backend lead for 8 weeks when the engineering lead left, coordinating a team of 7 engineers, reviewing architecture decisions, and unblocking contributors while continuing to ship.

Backend Engineer (Finalist)

HNG Internship

Finalist in a globally competitive engineering internship program, contributing backend systems for Sitelytics — a website analysis platform for non-technical users.

• ›Selected as a finalist among 22,000+ applicants — one of roughly 309 finalists globally.
• ›Built the Admin system from scratch — role-based access control, user monitoring, scan tracking, and admin-managed content — as a sole contributor.
• ›Built the platform notification system from scratch including retrieval, deletion, and email delivery through external providers.
• ›Built helper utilities that standardized notification delivery across the platform, eliminating inconsistent notification handling across services.
• ›Contributed to async website scanning pipelines using background workers and Server-Sent Events for real-time scan progress updates.
• ›Served as a frequent code reviewer across a 15-engineer backend team, maintaining code quality and consistency.
• ›Acted as temporary team lead for one week, coordinating contributors and unblocking work across the team.
