Front-End Engineer at Enbros Technologies

July 1, 2025 - Present

Architected a multi-tenant B2B security awareness platform with Admin, Client, and End-user dashboards using Next.js App Router, reducing initial page-load times by 35% across portals. Hardened the application against XSS and injection vectors by standardizing Next.js middleware and strict Content Security Policy (CSP) headers, and applying isomorphic DOM purification for client-facing routes. Eliminated runtime form failures by implementing a 100% type-safe validation layer (React Hook Form + Zod) integrated into centralized Axios interceptors, using TanStack Query for resilient cached server-state management and secure cookie-based sessions. Established a modular, accessible design system with Tailwind CSS, Radix UI, and Framer Motion, accelerating feature delivery velocity by 40% across the engineering team.

Front-End Engineer at Ginger

November 1, 2024 - June 1, 2025

Spearheaded end-to-end front-end architecture for Ginger’s B2B beauty e-commerce platform, unifying the buyer marketplace, invoice-financing workflows, and internal admin dashboard under one design system. Engineered global state and async data-fetching architecture with Redux Toolkit (RTK) and RTK Query, reducing redundant network requests across product catalogs and transactional flows. Built secure document upload and submission interfaces for supplier invoice financing, enabling 24-hour credit approvals and automated 30/60/90-day repayment tracking. Standardized role-based admin panels using RTK to streamline catalog management, merchant onboarding, order-fulfillment tracking, and automated credit-scoring workflows.

Front-End Engineer at PredictBeta

October 1, 2024 - November 1, 2025

Spearheaded the architectural design of a high-traffic sports prediction platform using Next.js, supporting thousands of concurrent users during peak match windows. Reduced redundant API overhead by 40% and minimized server load by decoupling server-state via React Query and implementing custom data-fetching hooks. Optimized rendering performance in data-heavy dashboards using React memoization (useMemo, useCallback) and dynamic code-splitting to eliminate UI jank while maintaining consistent 60 FPS. Implemented token-based authentication and route protection using Next.js middleware to establish a robust RBAC foundation. Decoupled business logic from presentation components, increasing unit test coverage and enabling a reusable, component-driven architecture.

Front-End Engineer at Ari Foods

June 1, 2023 - October 1, 2024

Rebuilt the core e-commerce platform using Next.js, TypeScript, and Shadcn UI, resulting in a 25% increase in mobile conversion rates due to improved Core Web Vitals (LCP/CLS). Designed and integrated secure checkout flows, product catalogs, and real-time order tracking systems, collaborating with backend teams to implement Two-Factor Authentication (2FA). Enforced strict WCAG accessibility guidelines and semantic HTML structures, boosting organic SEO traffic by 18% via optimized Open Graph metadata. Authored comprehensive unit and integration test suites using Jest and React Testing Library, reducing production regression bugs by 30%. Coordinated end-to-end payment gateway integrations with external international partners, ensuring reliable transactional states and clear error-handling boundaries.

Front-End Developer at Nervela Labs Innovative Africa

August 1, 2021 - June 1, 2023
