Hi! I'm an expert backend developer. Python, Django, Flask, FastAPI, Node.js are my key skills. The work I care about is the stuff under the surface: APIs, databases, real-time systems, and lately, the infrastructure holding AI products together. Most of my backend work has been in FinTech and SaaS: insurance management, custom accounting software, behavioral finance. These tend to be the projects where the backend actually matters: real-time data, concurrent users, and zero tolerance for downtime. I've also worked across health, EdTech, and real estate.

I build web scrapers that don't get blocked and don't break. 🛡️ If you've watched your bot get banned within minutes of hitting a site behind Cloudflare, DataDome, or Akamai — or inherited a brittle Selenium script that dies the moment the site changes — that's the problem I solve. I build data extraction systems designed to run for months, not days. 🔧 WHAT I BUILD High-volume scraping systems for: • E-commerce pricing & product data • Real estate listings • Business directories & lead generation • Contact extraction 🎯 THE HARD TARGETS This is where most scrapers fail and mine don't: • JavaScript-heavy SPAs, dynamic content, and infinite scroll • Login-gated pages • Serious anti-bot protection — Cloudflare, DataDome, Akamai, PerimeterX, CAPTCHA solving Where it's faster and more stable, I skip the headless browser entirely and reverse-engineer the site's internal API. For ongoing collection, I build scheduled crawlers with proxy rotation, session management, and browser fingerprint handling baked in. 💡 WHY CLIENTS HIRE ME Most scrapers on Upwork work once — on the developer's machine, on a good day. Mine ship with: • Retries, error handling, and failure alerts • Monitoring and scheduling, deployed on AWS or Docker — no babysitting • Clean, structured output: JSON, CSV, straight into PostgreSQL, or via a FastAPI endpoint — not a folder of messy HTML You'll also always know where the project stands. I communicate in plain English, flag risks early, and deliver fast. ⚙️ TECH STACK Python • JavaScript/TypeScript • Playwright • Selenium • Puppeteer • Scrapy • BeautifulSoup • FastAPI • Celery • Redis • Docker • AWS (EC2, Lambda, S3) • GitHub Actions Need the output AI-ready? I deliver structured data formatted for LLM and RAG ingestion. 📩 SEND ME A SITE Even one that's blocked every scraper you've thrown at it.

I am webscraping and data extraction expert. In more than 7 years working in this field, I have scraped more than 1500 different kind of websites (simple html, with javascript, with protection - limited number of requests, with login...) and save data in different formats or databases (.csv, .xls, .json, MySql, MongoDb, AWS DynamoDB, AWS RDS, AWS S3...). One website had ~130 millions of records (simple html and it was done for ~10 days). I am using proxies for rotating IPs so on every request I have different IP address. Also have big experience in scraping e-commerce websites like magento1, magento2, shopify, opencart, bigcommerce, woocommerce.... The tool I am using is my own code written in python, but I can use scrapy too. I am fast, efficient and responsible and I can find solution for most of problems online. So learning new things is not problem for me. If you are interested in collaboration - contact me anytime so we can make a deal. I am in Serbia, Europe, CEST time zone.
