About this gig
Full-stack developer with real AI/ML production experience. I build web apps and SaaS platforms end-to-end and ship them live.
RECENT WORK BUILT WITH MY TEAM
Salesleon (salesleon.ai): AI commerce automation used by 4,000+ businesses. AI collects orders and sends invoices inside WhatsApp, Messenger, Instagram, and TikTok chat, scores orders with a fraud model, syncs inventory, and dispatches couriers.
Peters PTE: AI-powered PTE exam evaluation platform.
Ybala, Megamart and Petzone: food, dropshipping and pet e-commerce platforms.
WHAT I CAN BUILD FOR YOU
Full stack apps and SaaS: Next.js, React, Vue, Svelte, Node.js, Python, PostgreSQL, MongoDB.
AI features: chatbots trained on your own data (RAG), LLM and OpenAI integration, scoring and prediction models.
Integrations: WhatsApp Business API, Meta, Shopify, WooCommerce, Stripe, payment and courier APIs.
Dashboards, admin panels, role based team access and analytics.
DevOps: Docker, CI/CD, cloud deployment and scaling.
You get clean documented code, source files and a live deployment, not a demo.
Message me with your idea and I will reply with a plan, timeline and fixed price.

FAQ
What do you need from me to start?
Your idea or existing repo, the features you want, any design or brand files, and access to services you already use. If you are not sure yet, just message me and I will map the scope with you first.
Can you add AI features to an app I already have?
Yes. I can plug an AI chatbot trained on your own data, an LLM powered workflow, or a scoring or prediction model into your existing codebase without rebuilding it from scratch.
Which tech stack do you work with?
Next.js, React, Vue or Svelte on the front end, Node.js or Python on the back end, with PostgreSQL or MongoDB, deployed to Vercel, AWS or your own server. I can also match a stack you are already running.
Do I own the code and do you support it after delivery?
You own everything. You get the full source code, documentation and a live deployment, plus free bug fixes for 30 days after delivery. Ongoing maintenance and new features are available as a monthly retainer.
