Rijyel S.

I’m a full-stack web developer specializing in building scalable web applications using React, Next.js, Node.js, and Python (FastAPI/Django). I build fast, clean, and production-ready systems, and integrate APIs, cloud services, and AI features where they add real business value. I’ve helped startups and teams streamline operations by building custom web apps, data pipelines, and automation workflows. Whether it’s integrating APIs, building real-time dashboards, or designing backend systems, I focus on reliability, performance, and clean architecture. Here’s what I do best: -Full-stack Web Development: React, Next.js, Node.js, Python, Django, Flask, FastAPI, Express.js, TypeScript, Tailwind CSS, Bootstrap -LLM Integrations & AI: OpenAI, LangChain, custom GPTs, vector databases (Pinecone, FAISS), RAG pipelines, prompt engineering, chatbot development -Automation & No-Code Tools: n8n, Zapier, Make (Integromat), Airtable, Notion API, Google Apps Script, API orchestration -Data Engineering & APIs: REST, GraphQL, WebSockets, ETL pipelines, web scraping (BeautifulSoup, Scrapy, Selenium), API development & integration -Machine Learning & AI Scripting: Python (Pandas, NumPy, Scikit-learn, TensorFlow, PyTorch), NLP, data preprocessing, model deployment -DevOps & Cloud: Docker, GitHub Actions, AWS (Lambda, EC2, S3), Google Cloud, Azure, CI/CD pipelines -Databases: PostgreSQL, MySQL, MongoDB, Firebase, Redis, Supabase -Other Expertise: Authentication (JWT, OAuth2), PDF generation, email automation, data visualization (Plotly, Matplotlib), performance optimization I stand out by delivering well-structured, production-grade systems with clear documentation and a strong focus on scalability and maintainability. let’s build something powerful together.
