Artem Kirienko is a seasoned Software Engineer with 13 years of experience building robust, production-grade web applications and microservices, currently contributing at Instacart from Vancouver. He specializes in Ruby on Rails and backend systems but brings full‑stack fluency including TypeScript, Puppeteer-based rendering, and modern frontend frameworks like React and Vue. Artem has a track record of owning reusable, cross-team services (GDPR-compliant queueing, rendering pipelines, real-time stats microservices) and leading cross-functional projects from discovery to delivery. He pairs strong engineering discipline—testing, CI/CD, performance tuning, and containerized deployments—with mentoring and product-facing communication. Trained in applied mathematics at MSU, he often applies algorithmic thinking to practical problems (e.g., packing and data aggregation optimizations) and has experience across fintech, edutech, ecommerce, and insurtech domains.
