⭐ Legacy System Modernization Expert | Django, FastAPI & Next.js Developer With 90+ completed projects and a 100% Job Success Score, I help businesses that have outgrown Excel and MS Access move to modern, scalable web applications. My background is unusual: I've spent years inside Access and Excel systems, so I understand exactly where they break down as a business grows — messy data, no real-time reporting, no multi-user support, no integrations. That experience now drives how I build the replacement: instead of guessing what a client needs, I know which pain points to solve first. ✅ What I Do Best - Convert Excel / Google Sheets / MS Access into full web-based systems - Build Shopify private apps and custom backend integrations - Develop high-performance REST APIs with FastAPI - Create modern admin dashboards with Next.js - Deploy complete solutions on VPS with Docker, Nginx & CI/CD pipelines 🚀 Independent & Client Projects (Outside Upwork) In addition to my verified Upwork history, I've delivered these projects independently: - Built IMSFlow — a cloud inventory + accounting platform with multi-channel sales integration (Shopify, WooCommerce, Amazon, eBay), order management, and full accounting reports (P&L, balance sheet, trial balance) - Migrated an MS Access inventory system to Django + PostgreSQL - Built Shopify API automation syncing orders/inventory with a custom CRM - Developed FastAPI middleware connecting WhatsApp orders to a MySQL database - Deployed production apps with Docker, Nginx, and GitHub Actions CI/CD 🛠 Core Technical Stack Backend: FastAPI, Django, Laravel Frontend: Next.js, React, TypeScript Databases: PostgreSQL, MySQL, SQL Server, Supabase Deployment: VPS, Docker, Nginx, CI/CD pipelines Integrations: Shopify Admin API, Webhooks, Automation ⭐ Why Clients Hire Me - Clear communication and business-first thinking (avg. response time under 4 hours) - Reliable delivery — 100% Job Success Score across 90+ completed projects - Proven experience modernizing legacy Access/Excel systems into scalable web apps - Full-cycle support: build → integrate → deploy → maintain If your business is running on Access, Excel, or a patchwork of disconnected tools and it's starting to hold you back, let's talk about what the next version looks like.
