Job Success
Ilesa, Nigeria - 12:27 am local time
Recent example: a client came to me with a Supabase backend full of broken queries and mismatched table relationships. I diagnosed the issues, repaired the relationships, and optimized performance delivered within 3 days. The client called the work "efficient" and said delivery "exceeded expectations." On a separate project, I supported a Lovable-based application through complex troubleshooting and improved its overall project stability, and was described as reliable with strong communication throughout.
WHAT I DO BEST
AI Agents & Automation
I build AI agents, autonomous workflows, and conversational chatbots using Claude AI, Claude Code, and n8n from first prototype through to a production system your team can actually run. This includes RAG-based assistants, support bots, and internal tools that remove repetitive work.
App Debugging & Rescue
When a Supabase, Lovable, or Replit app is broken, slow, or stuck, I dig into the actual cause broken queries, bad table relationships, auth issues, or performance bottlenecks and fix it properly instead of patching symptoms. I also take over half-finished MVPs and get them shippable.
API & Payment Integration
I connect the pieces your product needs to function as a business: Stripe and PayPal for billing, Twilio for calling and messaging, and custom REST/GraphQL APIs and webhooks tying your app to the tools you use.
WHAT I ALSO BUILD
CRM & WhatsApp Automation
Kommo, HubSpot, and Zoho CRM setup, pipeline automation, and WhatsApp chatbot integration for lead tracking and follow-up, so leads don't fall through the cracks between your marketing and your sales process.
AI Voice Agents & Calling Systems
Inbound and outbound AI calling using Vapi AI, Retell AI, and ElevenLabs, connected through Twilio or SIP trunking, for appointment booking, lead qualification, or customer support at a scale a small team can't staff manually.
Workflow & Business Process Automation
End-to-end automation using n8n, Zapier, and Makecom connecting Airtable, Firebase, Supabase, and your CRM, so data moves between your tools without anyone copying and pasting.
E-commerce Automation
Shopify and WooCommerce integrations inventory, order, and customer-communication automation connected into the CRM and messaging systems above.
AI Video & Product Content
For product launches, I can also generate AI product ads and promo video content using Higgsfield AI, Google Veo 3, Kling AI, and Sora alongside a build.

SaaS MVPs & Dashboards
For founders starting from scratch, I build full-stack MVPs Node.js/Python backends, React or no-code frontends, authentication, and database design plus the admin panels and dashboards needed to run the business once it's live. I build with multi-tenant structure in mind from day one, so the MVP can scale into a real SaaS platform instead of needing a rebuild at 100 users.
HOW I WORK
I start every project by understanding the actual business problem before touching code a broken query or missing agent is usually costing you leads or trust with your own users, not just a technical annoyance. I scope the work upfront, give a realistic timeline, and check in at each milestone rather than disappearing until delivery. If your existing stack is a bad fit for what you're trying to do, I'll say so before we start.
WHY CLIENTS HIRE ME
Clear communication from the very first message, with realistic timelines instead of overpromising. I respond within a few hours, explain technical issues in plain language, and flag risks before they become problems. My focus is production-ready work code that holds up after I'm gone, with documentation so your team isn't dependent on me for every change. I work directly with non-technical founders and alongside existing dev teams, adapting to your process rather than the other way around.
If your app is broken and you need someone to find the real cause and fix it properly, or you need an AI agent, chatbot, or automation workflow built into your product, message me with what you're working on. I'll tell you honestly whether I'm the right fit and what a realistic timeline looks like.
