Summary
👤
Senior🎓
Top SchoolSergey Toy is a Staff Software Engineer based in Singapore with over 17 years of hands-on experience building high-performance backend systems and distributed architectures using Ruby/Rails, Go, PostgreSQL, DynamoDB, and AWS Serverless. As founder of a software consultancy, he led teams of developers, DevOps engineers, and designers to deliver 100+ projects for well-known brands, often modernizing legacy systems or designing scalable greenfield platforms. He has a demonstrated knack for cost and performance optimization—one engagement with an AdTech client reduced their AWS bill by 500x while improving reliability. A pragmatic technical leader and mentor, Sergey practices a hands-off management style that empowers engineers to own solutions and uplifts code quality through reviews and test-suite improvements. Comfortable across multiple languages (Python, C/C++, JavaScript, PHP) and curious about Rust, he blends deep backend expertise with product-minded thinking from prior digital marketing and project management roles. Outside of client work he contributes to open-source and runs an independent consultancy focused on reliable, cost-effective architectures.
