Full Stack Developer | SaaS Developer | Laravel | AI Integration

You probably don't need another developer who waits for instructions. You need someone who understands the product, makes sensible technical decisions, and takes ownership end to end. I'm a Full Stack Developer specialising in Laravel, Flutter, and AI-powered SaaS platforms. I've built production systems for US clients across real estate, fintech, and SaaS including a LiDAR-based solar design feature and a DocuSign-style e-signature system built entirely from scratch. I design and develop scalable digital products across web and mobile, everything from SaaS platforms and marketplaces to fintech apps and AI-powered systems. Whether you need a robust Laravel backend, a cross-platform Flutter app, or a React Native mobile solution, I architect solutions with performance, security, and long-term maintainability in mind. Clients come to me when they want clean code and reliable delivery, not just a freelancer who disappears after go-live. I've worked with US-based clients across industries, including Real Estate, Solar Energy, and SaaS. For MyClientWave, an all-in-one CRM for marketing agencies based in New York, I built a DocuSign-like e-signature system entirely from scratch, eliminating their dependency on third-party tools and saving high recurring costs. I also engineered a solar design feature that uses LiDAR data to generate 3D models of a client's house, calculate the optimal sunlight path across the roof, and recommend the best panel placement, a genuinely complex geospatial and data-engineering challenge delivered end-to-end. For HouseJet, a US real estate platform with 25,000+ happy homeowners and 1,200+ expert agents, I built core features of a property search and listing platform connecting buyers, sellers, and local agents across the United States. If you're looking for a developer who can take on technically demanding, product-critical features and deliver them reliably, that's exactly what I do. Unlike most developers who just execute tickets, I treat your product like my own. I ask the right questions upfront, flag architectural risks before they become expensive problems, and communicate proactively throughout the project. My long-term client retention rate on Upwork reflects that approach most clients return for their next build. ✅ I have experience building: - SaaS Platforms (Laravel + React/Next.js) - Mobile Apps (Flutter & React Native — iOS & Android) - Marketplace & E-Commerce Platforms - CRM / ERP Systems - AI Agents, Chatbots & RAG Systems - Fintech & Payment Gateway Integrations - REST APIs & Third-Party Integrations - Custom E-Signature & Document Workflow Systems - Geospatial & LiDAR-Based Data Features - Real Estate Platforms & Property Search Engines ✅ My core tech stack: - Backend: Laravel, Node.js, Nest.js - Frontend: React.js, Next.js, Vue.js - Mobile: Flutter, React Native - AI/ML: OpenAI, LangChain, RAG Pipelines - Databases: MySQL, PostgreSQL, Firebase, Supabase - DevOps: Docker, CI/CD, AWS, DigitalOcean Thanks for taking the time to read this.
