Over several years of freelance work, I specialized in developing advanced automation systems and botting infrastructure using Python. A core focus was browser automation for high-demand environments like e-commerce, where I engineered custom sneaker bots and large-scale traffic systems. I designed centralized command-and-control interfaces to orchestrate bot fleets across multiple servers for high concurrency and flexibility. I have significant experience with anti-bot mechanisms and regularly built solutions that navigated evolving detection systems. For example, I developed a method for bypassing CAPTCHA challenges by programmatically dissecting SVG elements, using heuristics to identify and strip noise components, effectively reverse-engineering visual challenges without relying on third-party CAPTCHA-solving services. This required deep knowledge of web rendering, DOM manipulation, and adversarial thinking. My projects consistently pushed the boundary of automation by combining performance, resilience, and stealth, balancing efficiency with precision in highly competitive and protected online environments.

Conducted in-depth security audits and threat analysis, identifying vulnerabilities such as BGP exploits and database hijacking. Developed abuse prevention mechanisms and enhanced key management strategies to strengthen platform security while maintaining agility.

At XODEX.io, I led security initiatives and contributed as a senior Web3 developer, architecting the first self-custodial MPC wallet for Kaspa with multi-chain support, fully integrated within Telegram. I built high-performance Node.js APIs, secure data pipelines, and deployed a real-time Twitter sentiment analysis tool powered by a RAG-based AI model. Additionally, I reverse engineered competitor solutions to inform our product strategy and maintain a competitive edge. My role bridged protocol-level security with product development, ensuring both resilience and innovation in a fast-paced blockchain environment.
