I build web apps, APIs, automation systems, and AI-powered tools. I handle any software task — bug fixes, security reviews, refactoring, legacy migration, scripts, performance tuning, feature adds, full builds from scratch, API integrations, database optimization, system design, responsive UIs. I build web apps, mobile apps (React Native, Flutter), desktop apps (Electron, .NET MAUI), backend systems, microservices, monoliths, APIs (REST, GraphQL, gRPC), serverless functions, and AI tools. Domains: E-commerce (Shopify, WooCommerce, Stripe), CMS (Strapi, Sanity, WordPress, Drupal), real-time (Socket.io, WebRTC), DevOps (AWS, Docker, K8s, CI/CD), databases (PostgreSQL, MongoDB, Redis), AI/ML (OpenAI, LangChain, vector DBs), auth (OAuth, JWT, Auth0), message queues (RabbitMQ, Kafka). But more than that — I build entire projects from ground up. Requirements → Architecture → Development → Testing → Deployment → Maintenance. Full cycle. End to end. One client review: finished a 2-hour sprint perfectly, fixed core issues, caught security problems they missed, sent video walkthrough. No delays. Strongly recommended. That's my baseline for every project — Golang microservices, Rails monoliths, Java enterprise, Django backends, .NET systems, Node.js APIs, React dashboards, Vue apps, Next.js sites, e-commerce, mobile apps, or AI platforms. Give me any software task — mobile, web, desktop, backend, frontend, or entire project from scratch. I ship clean, fast, and right. less
