Senior🎓
Top SchoolRustam Sharshenov is a senior software engineer with 12 years of experience building and scaling backend web platforms, currently focused on high‑throughput systems and reliability at Amplemarket. He brings deep expertise in the Ruby/Rails ecosystem, PostgreSQL tuning, ElasticSearch, RabbitMQ, Kubernetes and AWS, and practical experience migrating monoliths to microservices while optimizing memory and performance (including low‑level profiling with gdb). A pragmatic mentor who prefers coaching over management, he’s delivered production improvements across startups and large teams—from CTO at a fashion search startup to engineering roles at Veeqo/Amazon. An active open‑source contributor, he has improved popular libraries like searchkick, json_api_client and sneakers and authored activejob-uniqueness used in production by organizations such as search.gov. Comfortable across DevOps, observability and infra as code, he chooses tools for the problem rather than the trend and often combines engineering craft with product-minded tradeoffs. Based in Swansea, he balances hands‑on troubleshooting with mentoring and continual learning to remain a T‑shaped engineer.
