Full-stack developer & digital creator — crafting web apps, mobile apps, and blockchain solutions that actually solve problems. Based in Nigeria, building for the world.
I'm Valentine — a full-stack developer and digital creator who started his journey in 2023 with a curiosity for video editing and design. That spark grew into a deep passion for building real digital products that make an impact.
From real estate clones to blockchain dApps, RPG games to mobile apps — I've built across the full spectrum of modern tech. I care about clean code, great UX, and shipping things that actually work.
Beyond the code, I create content on TikTok (@devnollex) sharing my developer journey and inspiring the next generation of African tech builders.
Technologies I work with
Full-Stack & Web3 Developer
Delivering full-cycle client projects — from scoping to deployment. Specializing in React web apps, responsive sites, and Web3 integrations for international clients.
Creating developer content that educates and inspires — covering web development, coding tips, project builds, and the African tech scene. Growing a community of aspiring developers.
Built and documented a highly responsive website while publishing technical articles combining real-world code examples with practical developer insights.
Implemented responsive React.js interfaces for real clients. Delivered pixel-perfect, mobile-optimized websites that consistently exceeded client expectations.
A showcase of my best builds — web apps, mobile apps, blockchain, and games. Every project is a real, shipped product.
A full backend system that transforms a static contractor or real estate website into an automated lead-generation machine. Enquiries from the website are captured, scored, and piped directly into a CRM dashboard — so agents and contractors never miss a deal.
A real-time currency exchange mobile application showing live FX rates, conversion tools, and currency pair tracking — built for Nigerians and diaspora managing international money flows.
A productivity mobile app with Pomodoro-style timers, task checklists, and session tracking to help developers and students stay in deep focus mode.
A full-featured order and logistics tracking dashboard — with real-time status updates, order management, and a clean data interface for businesses managing deliveries.
Production-level real estate agent profile — zero frameworks, pure HTML/CSS/JS. Features maps, listings, reviews, and full mobile responsiveness.
Full browser RPG — multiple locations, monster AI, weapon upgrades, XP system, and inventory. Built entirely in pure JavaScript.
Decentralized donation app on STT Testnet — MetaMask wallet integration, Solidity smart contract, and live on-chain transaction history.
My remaining projects — including advanced mobile builds, API integrations, and more — are reserved for serious clients and collaborators.

Every testimonial below is from a real client I worked with outside Nigeria — across real estate, contracting, and digital systems that generated measurable revenue.
Valentine built us a lead engine that completely changed how we do business. Within the first month, we closed over 50 qualified leads and had 12 hot prospects in the pipeline. The system auto-captures every website enquiry and routes it straight to our team. We closed a 6-figure contract deal because of a lead that came in at 2am — we'd have missed it without his system. Best investment we made this year.
I was skeptical at first but Valentine delivered way beyond what I expected. He built a full backend CRM for my real estate agency and within 6 weeks we had 6 active clients generating consistent revenue. The pipeline dashboard alone saved us hours every week tracking leads manually.
Our contracting firm had a website that just sat there doing nothing. Valentine turned it into a lead machine. We went from zero online enquiries to 12 qualified prospects in the first month. Three of them converted into contracts worth over $70,000 each. The ROI on this system is insane.
I hired Valentine to build a property listing system with lead capture and automated follow-up emails. What he delivered was professional grade — the kind of system agencies pay tens of thousands for. He was fast, responsive, and genuinely cared about the results. We closed 2 six-figure property deals directly from leads his system captured.
Working with Valentine was effortless. He understood our business immediately and built exactly what we needed — a clean dashboard showing all our leads, their status, and the pipeline value. Our sales team now closes 40% faster because they can see everything in one place. He delivered in 2 weeks and stayed on to make sure everything was perfect.
Valentine is the kind of developer every business needs — technical, strategic, and focused on results not just code. He built our entire lead generation backend from scratch. The email capture system, the CRM, the automated notifications — it all works flawlessly. Since launch we've generated over $200K in tracked pipeline revenue.
