I specialize in React, Next.js, Node.js, Go, Flutter, React Native, Python, and end-to-end automation using n8n, Make, and Zapier. I enjoy turning complex product ideas into reliable, scalable solutions. My recent work includes athlete management systems, real estate management platforms, and AI healthcare workflows with React, Supabase, PostgreSQL, LangChain, and OpenAI. I also design REST APIs, database schemas, and Docker-based CI/CD pipelines for cloud deployment. I have worked as a senior software engineer in remote environments, where I led full-stack development, reviewed code, made architecture decisions, and mentored other developers. I am comfortable working across frontend, backend, mobile, DevOps, and AI integration layers. In parallel, I work as an LLM trainer and AI evaluator, helping improve model outputs for code generation, reasoning, and software engineering tasks. This has strengthened my ability to assess correctness, security, and production readiness. I also have strong freelance experience on Upwork, where I maintain a 100% Job Success Score and 5-star reviews. I value clear communication, quality delivery, and building solutions that are practical, maintainable, and user-focused. ## Skills ### [Python](https://jobicy.com/talent/python.md)[AWS](https://jobicy.com/talent/aws.md)[JavaScript](https://jobicy.com/talent/javascript.md)[React](https://jobicy.com/talent/react.md)[Docker](https://jobicy.com/talent/docker.md)[CI CD](https://jobicy.com/talent/ci-cd.md)[TypeScript](https://jobicy.com/talent/typescript.md)[Software Engineering](https://jobicy.com/talent/software-engineering.md)[PostgreSQL](https://jobicy.com/talent/postgresql.md)[Go](https://jobicy.com/talent/go.md)[MongoDB](https://jobicy.com/talent/mongodb.md)[GraphQL](https://jobicy.com/talent/graphql.md)[Testing](https://jobicy.com/talent/testing.md)[Redis](https://jobicy.com/talent/redis.md)[Code Review](https://jobicy.com/talent/code-review.md)[React Native](https://jobicy.com/talent/react-native.md)[Next.js](https://jobicy.com/talent/next-js.md)[Integration Testing](https://jobicy.com/talent/integration-testing.md)[API Testing](https://jobicy.com/talent/api-testing.md)[Database Design](https://jobicy.com/talent/database-design.md)[Functional Testing](https://jobicy.com/talent/functional-testing.md)[Flutter](https://jobicy.com/talent/flutter.md)[Firebase](https://jobicy.com/talent/firebase.md)[Gemini](https://jobicy.com/talent/gemini.md)[WebSockets](https://jobicy.com/talent/websockets.md)[Dart](https://jobicy.com/talent/dart.md)[LangGraph](https://jobicy.com/talent/langgraph.md)[Supabase](https://jobicy.com/talent/supabase.md)[API Orchestration](https://jobicy.com/talent/api-orchestration.md)[RAG](https://jobicy.com/talent/rag.md) ##
