Hire the Best Java Developers
in Nigeria

I build reliable backend systems, REST APIs, and full-stack web applications that businesses can actually use in production. I’m a Backend & Full Stack Developer working primarily with Go, Node.js, Java/Spring Boot, React, and TypeScript. I focus on building clean APIs, database-driven applications, authentication systems, third-party integrations, and business platforms that are reliable, maintainable, and easy to extend. My core backend experience includes: • Go and Gin for high-performance REST APIs • Node.js and Express for scalable backend applications • Java and Spring Boot for structured enterprise-style systems • PostgreSQL, MySQL, and MongoDB for database design and data management • React and TypeScript for full-stack web applications • REST APIs, authentication, webhooks, and third-party API integrations • Stripe integration, including Checkout, subscriptions, payments, and webhooks I also have experience working on real business applications rather than only tutorial projects. One example is a supermarket POS and intelligence system I built for a client. The application brings together sales workflows, inventory management, authentication, dashboards, and backend services into one system designed around the client's business needs. I also built MedChain, a healthcare records platform designed to help hospitals manage patient information more efficiently. The system included offline access, QR-based patient identification, document handling, and data summarization. Working on projects like this has taught me to think beyond simply making code work and instead consider reliability, usability, and real-world constraints. Payment integration is another area I work extensively with. I've implemented Stripe Checkout, subscriptions, payment flows, and webhook handling, with a focus on making sure payment events are handled correctly and reliably. If you already have a backend that needs fixing, a new API that needs to be built, or a complete web application that needs to go from idea to working product, I can help. Send me a message with what you're building and what you need done. I'll give you a clear assessment of the best way to approach it.

Most SaaS ideas never become products people actually use. Some get stuck at the prototype stage. Others launch with broken workflows, weak UX, or a website that fails to communicate the value. I help founders close that gap turning ideas, Figma designs, and early-stage builds into launch-ready SaaS MVPs and high-converting Webflow experiences. From the marketing website to the actual product, I build with Webflow, Bubble, Lovable, Supabase, AI and API integrations. What I Can Build: ✓ SaaS MVP Development dashboards, client portals, marketplaces, membership platforms and subscription-based web apps ✓ Webflow Development SaaS websites, startup websites, landing pages, Figma to Webflow, CMS, responsive development and custom functionality ✓ Bubble Development SaaS applications, MVPs, marketplaces, dashboards, workflows and API integrations ✓ Lovable + Supabase Development rapid MVP development, authentication, databases, user roles, backend logic and production improvements ✓ AI Integration OpenAI, Claude, AI assistants, AI-powered features and intelligent workflows ✓ API Integration connect your SaaS with third-party platforms, external services and business tools ✓ Stripe Integration subscriptions, checkout, payments and SaaS billing workflows Building an MVP? You may already have the idea, Figma design, Lovable prototype, Bubble application, or partially completed SaaS but need someone to turn it into something people can actually use. I can help with: • User authentication and account systems • Supabase database and backend setup • SaaS dashboards and admin panels • Role-based user access • Stripe subscriptions and payments • AI and LLM integrations • REST API and third-party integrations • Database-driven functionality • Responsive frontend development • Debugging and improving existing MVPs • Taking AI-built prototypes toward production Need Webflow Instead? Webflow remains a core part of what I do. I build responsive, conversion-focused Webflow websites for SaaS companies, startups and growing businesses, including Figma to Webflow development, CMS websites, landing pages, animations and custom functionality. So whether you need the marketing website, the SaaS product, or both, you don't have to coordinate multiple developers just to get your idea launched. Technologies & Platforms: Webflow • Bubble • Lovable • Supabase • React • TypeScript • OpenAI • Claude • Stripe • REST APIs I care about more than making something look finished. I focus on building products that are usable, responsive, maintainable and aligned with what you're actually trying to launch. Have a SaaS idea, existing MVP, Webflow project, or AI application? Send me your requirements, Figma file, existing build, or project brief. I’ll review what you have and help you determine the most practical path to launch.

Your team is burning 40–60 hours a week on work that should run on autopilot. Chasing invoices, updating the CRM, following up with leads, sending appointment reminders, copying data between tools, scheduling content. If people are still doing these by hand, you don't have a workflow problem — you have a revenue leak. I'm Fawaz, an Automation Engineer. I design and build the backend systems that take this work off your team's plate — reliably, accurately, and at scale — using n8n, Make com, Zapier, and AI tools like Vapi, ElevenLabs, and Claude. WHAT I CAN BUILD FOR YOU AI voice agents that qualify leads, handle follow-ups, and book appointments on their own (Vapi, Retell AI, ElevenLabs) CRM and lead pipelines that capture, route, and nurture every contact with zero manual entry (GHL, HubSpot, Airtable, Notion) Client onboarding on autopilot — forms, contracts, welcome sequences, and task creation, all triggered the moment someone signs eCommerce backend automation — order syncing, abandoned cart recovery, inventory alerts, and Stripe reconciliation API and webhook integrations that connect your entire stack, however complex it is WHO I WORK WITH Agencies, real estate teams, eCommerce brands, coaches, medspas, hospitals, and SaaS startups — businesses scaling fast that would rather build systems than hire three more people to manage operations. WHAT YOU GET 40–60 hours a week back across your team Leads answered in seconds instead of hours Nothing slipping through the cracks — every contact tracked, every task triggered A backend that runs whether you're online or not, with dashboards, logs, and clean reporting so you always know what's happening Top Rated on Upwork. Every system I deliver is fully documented, tested, and handed off with a walkthrough, so your team can run it confidently without depending on me. NOT SURE WHERE TO START? Book a 45-minute Workflow Audit. I'll map your current process, show you exactly what to automate first, and hand you a clear build plan with a fixed-price or hourly estimate. Message me with your biggest operational headache — I'll turn it into a system.
