I am a Senior Software Developer with over 8 years of industry experience, focused on building scalable, high-quality web applications that deliver real business value. I specialize in modern frontend development and take full ownership of problems from discovery through delivery, consistently producing solutions that balance performance, usability, and long-term maintainability. I bring more than 5 years of hands-on experience with Bubble, alongside extensive work with CMS and commerce platforms including Shopify, WordPress, Sitecore, Contentful, and Strapi. My Shopify work includes custom theme development, storefront optimization, conversion rate improvements, and third-party integrations. I also have strong experience with Base44 and no-code tools, using them to rapidly prototype and ship production-ready SaaS systems. In addition, I actively build with AI-driven tools and workflows, including OpenAI integrations, automation pipelines, and AI-powered platforms such as Lovable, Replit, and Base44, always applied to real, revenue-generating use cases rather than experiments. My project experience spans e-commerce redesigns, interactive data visualization dashboards, single-page applications, payment gateway integrations, subscription management systems, Saas platforms, MVP building and scalable AI-enabled platforms.

Most Shopify stores don’t struggle because the products are bad. They struggle because the store isn’t built to convert. Slow performance, weak product positioning, poor mobile experience, generic messaging, and disconnected customer journeys quietly kill sales- especially in dropshipping. Whether you're just starting out or you've been running a store for a while, here's how I can help: FREE for beginners: If you're new to Shopify dropshipping and not sure where to start, send me a message. I offer a free strategy call to help you figure out your niche, store structure, and product direction — no cost, no obligation. FREE for store owners: If you already have a Shopify store but it's not performing the way you expected, I'll do a free conversion audit. I'll review your store and tell you exactly what's costing you sales — then you can decide if you'd like help fixing it. My work combines Shopify development, CRO, technical optimization, product research, and ecommerce growth strategy into one system focused on performance. Whether you need a complete Shopify store build, a high-converting landing page, advanced Shopify 2.0 customization, or store optimization for scaling, I focus on the areas that directly impact revenue, user experience, and conversion rate. What I help clients with: • Shopify store setup and Shopify 2.0 customization • Conversion-focused Shopify landing pages (PageFly, GemPages, Shogun) • Shopify speed optimization and Core Web Vitals improvement • Shopify CRO and conversion rate optimization • Product research for dropshipping and ecommerce brands • Technical Shopify SEO and product page optimization • Shopify app integration and store automation • Supplier sourcing and fulfillment workflow setup • Product listing optimization and store management • Google Shopping, Meta Ads, and TikTok ecommerce support • Klaviyo email flows and abandoned cart recovery I also support ecommerce brands with supplier sourcing through AliExpress, CJ Dropshipping, and Spocket, helping improve fulfillment reliability, product quality, and operational efficiency.

I build the kind of fintech dashboards where users stop complaining about the software. One client told me their platform "feels faster than our old desktop app" after we shipped — that's what happens when performance and UX aren't afterthoughts. With 4+ years building production React and Next.js applications, I specialize in data-heavy, enterprise-grade interfaces for fintech and SaaS products: transaction dashboards, admin panels, ERP-style workflows, and internal tools that teams actually want to open. I've worked on systems processing 500k+ daily transactions, where slow renders and clunky UIs cost real money. My stack is React, Next.js (App Router, SSR), Angular, TypeScript, and Tailwind CSS — but what I really bring is judgment. I know when to reach for SSR versus client rendering, when an architecture needs rethinking versus just cleaning up, and how to step into an existing codebase without blowing it up. I work closely with backend teams and designers, and I communicate in plain language — no status theater, just shipped features. If you're building a SaaS platform, a fintech product, or an internal tool your team will actually use every day, let's talk. Send me a message and tell me what you're working on.

Most teams only discover their AI agents' critical failures after silent token burns, hallucinations, or lost user trust in production. I build the infrastructure and verification layers that catch these issues before they scale. What I build: - Reliable local and edge AI agents using Python with real browser interaction and human-in-the-loop design - Production MCP (Model Context Protocol) servers and agentic RAG pipelines - Federated AI Knowledge Commons using ActivityPub for verifiable decentralized knowledge - Cost-optimized semantic search and document retrieval systems - Observability and verification layers for production agent systems Current Focus: - **NaijaVPN** — Virtual Payment Navigator and professional invoice tools for Nigerian freelancers and creators - Local Python AI agents, including an SEO Audit Agent that I dogfooded on my own domains (improved from 0/4 to 4/4 PASS in one afternoon) - Federated knowledge systems designed to combat knowledge collapse Stack: Python, Playwright, Claude, Cloudflare Workers, Vectorize, MCP, RAG, ActivityPub, TypeScript, React, Node.js Track Record: - Author of widely discussed DEV.to series on AI and developer work including "Knowledge Collapse", "Above the API", and edge computing pieces — over 50,000+ views combined - Built and shipped multiple production AI agent tools (spec-writer, voice-humanizer, SEO Audit Agent, vectorize-mcp-worker) - Contributor to freeCodeCamp and high-star GitHub repositories - Delivered an AI FAQ system for an e-commerce client that achieved 70% reduction in support tickets (5-star review) I write clean, well-documented code with strong focus on reliability in real production environments rather than just demos. Available 30+ hours per week. If you need robust Python AI agents, MCP infrastructure, RAG systems, or production-ready agent tooling that actually works at scale — send me a message.
