Pelumi Isaac O.
Full-Stack Developer | WordPress, MERN, Next.js & Web App Deployment
Full-Stack Developer | React, Next.js, Node.js, WordPress, AWS I turn business requirements, prototypes, and Figma designs into working digital products — functional web apps, dashboards, and automated systems that clients can actually launch, use, and grow with. I work across the full stack: frontend, backend, databases, APIs, AI integration, and deployment — so a client doesn't need to hire five specialists to get one product built correctly. How I Help Full-Stack Web App Development — React, Next.js, Node.js, NestJS, and MERN-stack builds with authentication, admin dashboards, and clean, scalable architecture WordPress Development — custom themes, plugins, Figma-to-WordPress builds, CMS-limitation workarounds, and ongoing site support API & Database Integration — REST APIs, PostgreSQL/MongoDB/Supabase database design, and integrations with payment systems, CRMs (GoHighLevel), and financial APIs (Currencycloud) AI-Powered Applications — AI assistants, chatbots, and automation workflows built on n8n and Make, with proper frontend-to-backend communication rather than a bolted-on AI widget Search, Filters & Dashboards — dynamic search/filter systems and data-driven admin/reporting dashboards Deployment & Infrastructure — Vercel, AWS, Render, DigitalOcean, cPanel, Nginx Performance, SEO & Tracking — Core Web Vitals/page speed optimization, technical SEO, GA4/GTM setup, Google Ads and Meta Pixel tracking Rebuilds & Debugging — fixing and modernizing apps that are slow, broken, or outgrown their original build Every build is responsive, mobile-first, and SEO-friendly from day one, with security and scalability considered from the architecture stage — not patched on afterward. Selected Work TryRaro / TryRiffly / Here2Helpu — product-focused web platforms built around real user journeys, not template pages Salt Strategy Group AI / Mozaik AI Assistant — AI-powered applications with full frontend-backend-data integration WhatsApp-first AI-driven platform (Node.js, Supabase) — automation-oriented system connecting a communication channel to a full backend, not just a website Remitwave (Laravel, Currencycloud) — financial application requiring careful handling of external APIs and transactional data Med'ease Healthcare MVP — multi-module healthcare coordination platform with GDPR, HDS hosting, and FHIR interoperability considerations Teachly (React Native, Node.js, AWS) — cross-layer product spanning mobile, backend, and cloud infrastructure Delivered a white-labeled GoHighLevel CRM for a life insurance agency client Built a Computer-Based Test platform with anti-cheat detection and auto-generated candidate IDs Connected two Shopify stores to a Supabase database for a UK eyewear brand 4.8-star rating across 94 client reviews for full-stack and web app development Problems I Solve "I have a design but no working website" → I convert it into a responsive, functional application "I have a prototype that doesn't actually work yet" → I add the backend logic, database, auth, and deployment it needs "I need my app to connect to another service" → API and third-party integration work (payments, AI, CRMs, financial services) "I need more than a website" → SaaS platforms, dashboards, automation systems, and API-driven products Next Step Send me your project brief — the idea, must-have features, and any Figma/design reference you have. No design yet? I can help build that out too. I'll scope it and walk you through it step-by-step from there.
