Summary
👤
Senior🎓
Top SchoolAleksander Szmigiel is a Senior Software Engineer with 11 years of experience building high-performance web and anti-bot systems from Poland. He has deep front-end expertise (Angular, Next.js, ReactNative) combined with backend skills in Node/Express and GraphQL, and a history of shipping high Web Vitals and >95% test coverage across products. Aleksander has notable reverse-engineering experience—deobfuscating Antibot systems (Akamai, Accertify, ThreatMetrix) and creating tooling and Chromium patches to preserve real-user fingerprints for scraping-resistant environments. He’s contributed to both product and infrastructure: landing pages, microservice-ready fast APIs, and developer-facing SDKs and consoles. As a former co-founder and long-time eSky contributor, he blends startup pragmatism with enterprise-grade engineering discipline. Based in Psary, he pairs performance-first web engineering with uncommon low-level anti-bot and browser-fingerprinting know-how.
