Summary
👤
Senior🎓
Top SchoolIlya Bazylchuk is a senior software engineer based in Valencia with over a decade of experience building and scaling backend platforms for high-growth products. He thinks in terms of product outcomes rather than just code, having driven StartWire from 50k to 20M users and managed all engineering and DevOps responsibilities as a solo contributor. His strengths include integrating complex ATS ecosystems, designing large-scale search solutions with Elasticsearch for datasets exceeding 30M records, and operating high-volume email systems delivering millions of personalized messages daily. At NXTThing RPO he combined architecture, integrations, and cloud DevOps to streamline recruiting workflows, and he now contributes product-level engineering at Appcast. Comfortable across stacks and life-cycle stages, he blends hands-on development with operational ownership and a knack for turning data-heavy pipelines into profitable, user-focused features. An often-overlooked asset is his sustained focus on SEO and deliverability as core growth levers, not just marketing afterthoughts.
