Over the past long years, I've delivered 8+ production platforms across SaaS, EdTech, and eCommerce using Python (Django/FastAPI) and React/Next.js. My work has helped clients improve performance by up to 40%, automate up to 70% of manual workflows, and increase conversions through better UX and system design. Recently, I built: ✅An AI SaaS platform using GPT-4.1 that processes thousands of inputs daily ✅A scalable EdTech system serving thousands of monthly users ✅Multiple business websites that boosted traffic, SEO rankings, and online sales I focus on: ✅Clean, scalable backend architecture ✅Fast, SEO-optimized frontend (Next.js) ✅AI integrations (OpenAI APIs, automation) ✅Payments & subscriptions (Stripe) 🌐 Web Development & Full-Stack SaaS I build SEO-ready, high-conversion web platforms with Next.js, React, and the TanStack ecosystem (Query, Router, Table, Form). From dynamic social feeds and dashboards to admin panels and payment flows — server-side rendering, API routes, real-time updates, and cloud deployment on Vercel, AWS, or self-hosted infrastructure. 📱 Mobile Development (iOS & Android) I deliver native-feeling cross-platform apps with React Native and Flutter, shared business logic, offline-first patterns, push notifications, in-app purchases, and App Store / Google Play release pipelines. TanStack Query and modern state management keep data sync smooth and the UI responsive on every device. 🤖 AI Development & Intelligent Products I integrate LLMs, RAG pipelines, embeddings, and custom ML models into production apps — chatbots, recommendations, content moderation, image/audio generation, and workflow automation. Python (FastAPI, LangChain), OpenAI/Anthropic APIs, vector DBs (Pinecone, Supabase pgvector), and fine-tuning workflows — built for scale, cost control, and real user value. 🎮 Game Development I create engaging interactive experiences from casual mobile games to multiplayer web games and serious gamification inside SaaS products. Unity (C#) and Unreal Engine for 3D and mobile titles; Phaser, Three.js, and PixiJS for browser games; plus backend matchmaking, leaderboards, and real-time sync with WebSockets, Firebase, or custom Node/Python servers. I'm not the type to just "deliver tasks" - I think in terms of product and business impact. If something can be faster, simpler, or more scalable, I'll call it out and fix it. If you need someone who can take a feature from idea → production without hand-holding, we'll get along well. Let's build something solid. less -
