Summary
👤
SeniorConstantin Slednev is a Senior Software Engineer with 15 years’ experience building scalable Python systems, from scraping pipelines to web platforms, and a strong focus on architecture and cost-efficient operations. He has a track record of shaving infrastructure costs—migrating workloads to Hetzner bare-metal and re-architecting services to reduce AWS usage by up to 70%—and has repeatedly helped teams deliver projects faster and cheaper by assembling remote talent. Comfortable across Django, Flask, Scrapy, Postgres, Redis and a variety of SQL/NoSQL stores, he thrives in emergency rescue missions and long-term product builds alike. A pragmatic problem-solver, he combines hands-on implementation with strategic design to get customers to market first. Outside work he balances a busy family life and diverse interests from boxing to metal-detecting, which feed a disciplined, curious approach to engineering.
