🏆Most developers write the code and vanish. I stay. Building software since before smartphones existed - and still at the frontier today, shipping AI-powered apps, ERP systems, and mobile platforms that outlast the hype. In 18 years of building software, the one thing I've learned is that the real work begins after launch - when users push your app in directions you never planned, when scale exposes the corners you didn't know existed, and when the business evolves faster than the original spec. That's exactly where I show up, not just at the start. I build in the AI era the same way I've built for nearly two decades - with purpose, with ownership, and with a long-term eye on what your product needs to survive and grow. Not just what looks good in a demo. What I Build 🔹AI Applications – LLM integrations, automation, smart workflows 🔹Mobile Apps – Flutter & React Native (iOS + Android) 🔹Web & SaaS Platforms – React, Next.js, Laravel, .NET 🔹ERP / CRM / POS Systems – Custom business platforms 🔹APIs & Automation – Seamless system integrations What makes me different: Anyone can write code. Fewer can architect a system that scales. Even fewer stay invested in your success after the invoice is paid. I've delivered 80+ projects across healthcare, logistics, fintech, e-commerce, education, and enterprise - and the clients who come back aren't coming back because I was the cheapest option. They come back because when something needed fixing at 11pm before a client demo, I was there. A few things I've shipped: 📌 RunTailor Mobile App - two-sided marketplace connecting customers with tailors and boutiques, live on Play Store and App Store 📌 AIMS360 Apparel ERP - end-to-end fashion industry ERP covering design, production, inventory, and order management for apparel businesses at scale 📌 Stellify POS - full-featured point of sale system built for retail operations, handling transactions, inventory, and reporting in real time 📌 AuditXtra Mobile App- mobile audit and compliance app enabling field teams to conduct inspections, capture evidence, and generate compliance reports on the go 📌 UiPath Custom Activity (RPA) - enterprise-grade C#/.NET automation development, 5-star reviewed on Upwork 📌 ERP & CRM Platforms - custom enterprise systems replacing legacy software for mid-size businesses 📌 FedEx-Integrated Shipping Platform (API Integration)- real-time parcel tracking and logistics web application Technologies & Tools 🔹Frontend: React.js · Next.js · Angular · Vue.js · TypeScript · TailwindCSS · Bootstrap · Material UI 🔹Backend: Node.js · NestJS · ASP.NET Core · Laravel · CodeIgniter · PHP · CakePHP · REST APIs · GraphQL · WebSockets 🔹Mobile: Flutter · FlutterFlow · React Native · iOS · Android · Deep Linking · Push Notifications · Firebase · In-App Purchases 🔹Database: SQL Server · PostgreSQL · MongoDB · MySQL · Firebase · Supabase · Redis 🔹Cloud & DevOps: AWS · Azure · Google Cloud · Docker · CI/CD · S3 · Cloud Deployment 🔹AI & Integrations: OpenAI · ChatGPT API · LLM Integration · Stripe · PayPal · Twilio · SendGrid · FedEx API 🔹Business Solutions: ERP · CRM · POS Systems · SaaS · MVP · E-commerce · WooCommerce · Marketplace · Admin Dashboards · LMS 🔹Languages: C# · PHP · Python · JavaScript · TypeScript · Java · Kotlin · Dart My promise to you: I will tell you what your product actually needs - not what sounds impressive in a proposal. I will flag risks before they become problems. I will be reachable, honest, and invested from day one to long after go-live.

Stack: Next.js, LangGraph, LangSmith, PostgreSQL. 💡 AI goal management coach (Productivity SaaS) - Personal coach PWA built in 3 months. AI breaks goals into milestones, sets reminders, tracks progress. Result: 50% faster task execution for users. 💡 AI platform for insurance brokers (InsurTech) - Modernized the UX of an AI-powered broker tool. Saved 1,500+ hours of broker time annually. Redesigned 10+ core workflows, integrated Stripe credit management and document previews. What I build: - AI chatbots that understand context (not just keywords) - AI agents that execute multi-step workflows autonomously - RAG systems that let AI answer from your company's knowledge base - Generative AI features embedded into SaaS products - AI-powered onboarding, support, and automation flows Tech stack: OpenAI, Anthropic Claude, LangChain, LangGraph, Amazon Bedrock, AWS, Next.js, React, Node.js, Python, PostgreSQL, Stripe Industries: FinTech, EdTech, InsurTech, Healthcare, Manufacturing, Logistics Every project starts with: what problem costs you time or money right now?
