Emmanuel Okon

Performance-driven Frontend Engineer with over 4 years of experience architecting high-performance, secure, and accessible web applications using React, Next.js, and TypeScript. Proven track record of leading distributed international teams (UK, Nigeria, Rwanda) to deliver scalable B2B enterprise dashboards and high-traffic consumer platforms. Expert in optimizing server-state management, engineering type-safe architectures, and implementing security-minded frontend practices (RBAC, CSP, and Middleware) that directly improve core web vitals and business conversion rates.

Frontend Engineer at Enbros Technologies (2025-07 – Present)

• Architected and scaled a multi-tenant B2B security awareness platform (Admin, Client, and End-user dashboards) using Next.js App Router, reducing initial page load times by 35% across all portals.
• Hardened application security against XSS and injection vulnerabilities by implementing Next.js Middleware, strict Content Security Policy (CSP) headers, and isomorphic sanitization via DOMPurify.
• Eliminated runtime form errors by building a 100% type-safe validation layer using React Hook Form and Zod, integrated with centralized Axios interceptors for secure, cookie-based session management.
• Established a modular, accessible UI design system using Tailwind CSS, Radix UI, and Framer Motion, which accelerated feature delivery speed across the engineering team by 40%.

Frontend Engineer at PredictBeta Nigeria Limited (2024-10 – 2025-11)

• Spearheaded the architectural design of a high-traffic sports prediction platform using Next.js, successfully supporting thousands of concurrent users during peak match windows.
• Decreased 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 dashboard views using React memoization (useMemo, useCallback) and dynamic code-splitting, eliminating UI jank and maintaining a consistent 60 FPS.
• Implemented token-based authentication and route protection using Next.js Middleware, establishing a robust foundation for Role-Based Access Control (RBAC).
• Decoupled business logic from presentational components, increasing unit test coverage and establishing a highly reusable, component-driven architecture.

Frontend Engineer at Afri Foods Ltd (2023-10 – 2024-11)

• 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% through 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 error-handling boundaries.

Frontend Developer at Nervelabs Innovative Africa (2022-06 – 2023-11)

• Engineered an end-to-end event management and ticketing platform, integrating Clerk for user authentication and Stripe for secure, multi-currency payment processing.
• Configured Redux Toolkit to manage complex global states across dynamic shopping carts, wishlists, and user profiles, ensuring predictable data flows.
• Reduced production error rates by 22% by integrating Sentry error monitoring and establishing automated deployment pipelines via Vercel.
• Conducted technical peer code reviews and established team-wide linting/formatting standards (ESLint, Prettier), improving overall codebase maintainability.

Frontend Developer at Matriks Hub (2021-08 – 2022-05)

• Designed and delivered a comprehensive modern JavaScript curriculum, successfully mentoring and training over 10 junior developers into professional engineering roles.
• Managed a team of 3 junior developers, coordinating sprint tasks, reviewing code submissions, and ensuring high-quality UI implementation.
