Full Stack & ERPNext Developer, AI-Assisted Delivery

I'm a Technical Lead with 9+ years of experience, served 500+ clients, leading and developing everything from scratch, architecture to MVP to production ready systems. I build full-stack web and mobile applications, custom apps for ERPNext/Frappe systems, and custom AI agents, using AI-assisted workflows to deliver faster without cutting corners. ZATCA compliance, custom modules, SaaS platforms, and intelligent automation for businesses. What I Do: → ERPNext / Frappe & Business Systems: I specialize in ERPNext and Frappe, from custom module development and multi-tenant deployments to ZATCA Phase 2 e-invoicing compliance. I've implemented and upgraded ERP systems for 90+ SMEs, diagnosed and resolved critical ZATCA compliance errors for 150+ SMEs, and contributed code to the open-source Frappe, ERPNext, and zatca_erpgulf repositories. I also have hands-on experience with Odoo ERP across Retail and F&B verticals. → Full-Stack Web & SaaS Development: I build production-grade applications using Python, JavaScript, TypeScript, React, Vue.js, Node.js, and .NET. I've delivered 25+ web platforms end-to-end, including a Brands & Influencer Marketing Platform (UK), a Real Estate Investment System (Nigeria/UK), a SaaS-based ERP (UK), custom ERPs for Real Estate flipping, Advertisement/Printing, and Ecommerce for Automatic Doors industries. I've also built specialized platforms, a Dermatology/Cosmetology booking platform, and a food ordering app. → Technical Leadership & Project Management: I've served as Technical Lead / Solutions & Engineering Manager, managing distributed teams across countries and delivering 25+ projects using Agile/Scrum. I've been a Scrum Master (California, remote), facilitating ceremonies for multiple engineering teams. And I was promoted to Project Owner & Head of Development (UK), overseeing a 10+ member team, defining product roadmaps, and managing full project lifecycles. I hold Google Certified Agile Project Manager, Google Certified Project Manager, and Scrum Master certifications. → AI-Assisted Delivery: I leverage AI (OpenAI, Claude, Gemini, LangChain, RAG, AI Agents) to accelerate full development lifecycle. This approach has reduced initial MVP development time by 75% on recent projects, which means faster delivery and lower cost for you, without sacrificing quality. → AI Agents & Automation: I develop custom AI agents and automated workflows for businesses, n8n pipelines, RAG-powered chatbots, MCP-based tools, and dynamic agent systems. Use cases I've built: customer support agents that resolve tickets autonomously, intelligent booking and appointment schedulers, lead qualification bots that engage website visitors, and automated workflows that connect your CRM, ERP, and communication tools. → DevOps & Infrastructure: I managed Linux/Ubuntu servers, cloud infrastructure (Digital Ocean, Hetzner), containerization (Docker), CI/CD pipelines, self-hosting platforms (Caprover, Coolify, Webmin), web servers (Nginx), and version control (Git).
