Python Developer with 5+ years building production backends, web scrapers, and automation systems. I specialize in Django, FastAPI, Selenium, Scrapy, Playwright, and AI automation — delivering scalable APIs, intelligent crawlers, and bots that turn manual work into reliable, automated pipelines. ⭐ 889+ hours billed on Upwork across 19 successful projects ⭐ Backend systems handling millions of records with PostgreSQL, Redis & Docker ⭐ Data scraping for JavaScript-heavy sites and dynamic content ⭐ AI-powered automation with OpenAI, Claude, LangChain & LangGraph ⭐ Clean, tested, production-ready code 🔹 What I build for clients: - High-performance REST & async APIs with FastAPI, Django, and Flask - Web scraping & data extraction with Selenium, Scrapy, Playwright, BeautifulSoup - Automation bots for data collection, workflow, messaging, and desktop tasks - AI agents & LLM workflows with LangChain, LangGraph, OpenAI, and Claude - ETL pipelines with PostgreSQL, MySQL, Redis, and Celery - Dockerized deployments with CI/CD on AWS, Render, and DigitalOcean - Secure authentication with JWT, OAuth2, and role-based access control 🔹 Python Backend Development I design backend architectures that handle real workloads — microservices with FastAPI and Django, async PostgreSQL queries, Celery + Redis for background jobs, and RabbitMQ for distributed tasks. I build APIs that integrate cleanly with third-party services (Stripe, Twilio, OpenAI, Google APIs) and deploy them with Docker and Nginx for fault-tolerant production environments. 🔹 Web Scraping & Data Extraction I build Python scrapers that handle complex sites — dynamic React/Vue/Angular content, authenticated sessions, and public REST/GraphQL APIs. I work with both browser automation (Selenium, Playwright) and pure HTTP scrapers (Scrapy, Requests) depending on what the target source needs. Data is cleaned, validated, and delivered in CSV, JSON, Excel, or directly to your database. I only work with public data or sources you have authorization to access. 🔹 AI Automation & LLM Integration I build production-grade AI systems using LangChain, LangGraph, and Langfuse — from simple LLM workflows to multi-agent systems with tool use, memory, and state management. I integrate OpenAI, Claude, and other LLM APIs for text parsing, data enrichment, classification, summarization, and intelligent agents. I build RAG systems with vector databases (Pinecone, Chroma, pgvector), prompt pipelines, and AI-powered ETL flows that turn unstructured data into structured business insights. With Langfuse, I add full observability — tracing, evaluation, and cost monitoring for every LLM call in production. 🔹 Selected Projects - AI-Powered Job Data Pipeline — Async FastAPI ETL ingesting XML feeds, AI enrichment, syncing to external APIs via Docker - Script Marketplace Platform — FastAPI + Docker SDK platform running isolated bot containers with task scheduling and live monitoring - Browser Automation Desktop App — Tkinter-based tool with advanced Selenium logic, session handling, and modular UI - Multi-Tenant E-Commerce ERP — Django + gRPC + Stripe + PostgreSQL with real-time order tracking - Financial Intelligence Dashboard — Python Dash analytics platform for structured financial data - PyQt5 WhatsApp Automation — Desktop messaging automation with a polished GUI - HLS to RTSP Conversion API — FastAPI service for live video stream conversion 🔹 Frontend (when needed) I focus on Python backend, but I can build clean, functional UIs in React, HTML, CSS, and JavaScript when a project needs an integrated frontend — so you don't have to hire two people for one workflow. 🔹 How I work ✓ Agile development with Git, GitHub, and Jira ✓ Clear daily communication and status updates ✓ Clean, modular code with proper testing and documentation ✓ Honest timelines — I tell you what's realistic, not what you want to hear ✓ Post-delivery support and revisions included 💬 Send me a message with your project details — I respond within a few hours and I'm happy to review your requirements before you commit to anything.

I'm a Python developer with a strong expertise in web scraping. I specialize in this area and I'm proficient in using popular Python web scraping tools like BeautifulSoup, Selenium, and Scrapy. I truly enjoy working on web scraping projects, and I'm highly skilled at it. What sets me apart is my meticulous approach to scraper development. I pay attention to the small details, and I'm able to optimize at the thread level to make sure the scraper uses as little computer resources as possible. This not only saves costs but also bandwidth. I'm also skilled at efficiently handling multiple requests at the same time. Furthermore, I have experience in data processing, data analysis, and data cleaning using frameworks like pandas. If you're in need of a web scraping and data expert, I'm the right person for your project.
