Match Score — ruby on rails developer

The candidate has over nine years of experience with a strong emphasis on Ruby on Rails across multiple recent senior roles from 2020 to present, including F. work achieving 99.99% uptime and 10x page load improvements, directly matching the Ruby on Rails developer role. Key strengths include continuous hands-on RoR development, full-stack capabilities with React, database optimization (PostgreSQL, SQL), AWS, Docker, and impactful achievements like supporting 1M+ users and launching platforms. Relevant skills such as APIs, Elasticsearch, Redis, and Agile methodologies are evidenced in recent positions. Minor concerns are some short F. stints and overlapping dates (e.g., 2018-2020), typical for contractors but warrant verification; no stale skills as all RoR experience is current and progressive to senior level. Education in Computer Science and certifications (AWS, Elasticsearch, SQL) add value. Overall, exceptional recency, depth, and impact justify the high score.
