I build web scraping and data extraction systems for targets that fight back, and I reverse engineer how they lock people out in the first place. Session-gated APIs, fingerprinted browsers, anti-bot layers built to stop the lazy approach. WEB SCRAPING & REVERSE ENGINEERING - JavaScript, Playwright, Puppeteer, Selenium - Python: requests, BeautifulSoup, Scrapy, lxml - curl_cffi, tls-client (TLS/JA3/JA4 fingerprint impersonation) - undetected-chromedriver, playwright-stealth, Chrome DevTools Protocol (CDP) manipulation - jadx, APKTool, dex2jar (Android decompiling and rebuilding) - Frida (custom hooks and scripting), objection - Ghidra, IDA Pro (static/binary reverse engineering) - Android emulators (AVD), ADB, root/Magisk and Play Integrity attestation analysis - Burp Suite, HTTP Toolkit, Postman, mitmproxy, Charles Proxy - Wireshark (packet and TLS-level network analysis) - Session and token mechanics, rate-limit behavior, CAPTCHA/anti-bot challenge analysis - Proxy rotation (residential/datacenter/ISP), distributed scraping (Scrapy-Redis, Celery) - Node.js (for Puppeteer-based tooling) BACKEND & INFRASTRUCTURE - Java, Spring Boot, Spring Security (OAuth2/JWT) - Microservices architecture, API gateways, Maven/Gradle, Hibernate/JPA - PostgreSQL, MySQL, Supabase, SQLite/SQLCipher, Elasticsearch - Redis, RabbitMQ, Kafka - Linux, Nginx, WebSockets/gRPC - Docker, Kubernetes, Terraform, CI/CD (Git, GitHub Actions/Jenkins) - Cloudflare/Wrangler, Fly(dot)io, AWS/GCP - Prometheus/Grafana (monitoring), JavaFX (desktop Java apps) ANTIDETECT BROWSERS - Multilogin (Previously worked in this company) - Adspower - Dolphin anty FRONTEND - Angular, React (latest versions, standalone components, Signals) - RxJS, NgRx and state management - Angular Material, PrimeNG - TypeScript, SCSS/SASS - Browser extension development (Chrome/Firefox, native messaging hosts) - Responsive and cross-browser UI, REST/GraphQL API integration Proof this isn't just theory: I built and run BrowserPulse, a live SaaS that scores antidetect browser profile health, tracks fingerprint drift, and checks IP quality, all data signals pulled from the same systems I reverse engineer. If your project needs data out of a target that's actively trying to stop that, an API or app reverse engineered to see how it really authenticates, a senior Angular/Java build, or backend infrastructure done right, message me. I'll tell you straight what's possible before you pay to find out.
