About
I’m a senior full-stack engineer and AI engineer with 10+ years of experience building high-scale distributed systems across e-commerce, fitness, and real estate—specializing in TypeScript, Ruby on Rails, AWS, and Kubernetes. I enjoy taking ownership of end-to-end delivery: from designing robust backend services and data pipelines to building responsive frontends and reliable CI/CD workflows.
I’ve built and operated production systems at substantial scale (millions of users/jobs), including automation pipelines for scraping/normalizing product data, orchestration systems for pricing and event-driven processing, and cloud-native microservices running on AWS (EKS, Lambda, S3). I also develop AI-powered agent workflows for classification/filtering and operational automation, while partnering closely with backend teams, product owners, QA, and designers to ship features that are fast, secure, and maintainable.

Built AI agent workflows for scraping/normalizing large product datasets (500k+ products), integrated with payment provider services and custom clearance agents. Designed additional agents to automate prohibited-product filtering and to streamline operations such as creating air waybills, scheduling daily shipment-related tasks, and automating product ordering via Amazon Business API. Focused on end-to-end automation and operational reliability.
Designed and delivered a large-scale automation and orchestration system (about 5M jobs/day) for Amazon product ordering and scraping. Implemented pricing engine, logs management, and incident management systems. Used AWS EKS, Sidekiq, Rails, Selenium, and Helm for high-scale orchestration; built and maintained reliable pipelines and deployment automation.
Migrated a large Ruby monolith to microservices powering property listings and search used by millions of global users. Worked on premium subscription systems running across apps, led unified user data migration, and built an internal React admin tool. Improved developer workflows and service performance across multiple teams.
