About Muttashim Sarkar
I’m a Software Engineer with over 5 years of experience building scalable backend systems at Amazon, currently working as an SDE 2. I\'ve led the design and development of systems handling high traffic and large datasets — including a multi-tenant GraphQL data aggregator (5M+ req/day), traffic shaping for noisy clients (110M+ req/day), and a real-time notification data warehouse (25M+ records/day). I’ve also driven performance and cost improvements, such as reducing latency by 70% and improving resource utilization from ~50% to over 90%. My core stack includes Java, Spring, GraphQL, JavaScript/TypeScript, and AWS. I\'m passionate about backend architecture, system performance, developer experience, and end-to-end ownership. Notable projects: – Multi-tenant GraphQL aggregator with federated schemas and OTA updates – Shareable transaction image generation from HTML views – Streaming data warehouse for real-time and batch analytics – Federated widget deployment framework for micro-frontend platform Open to opportunities in senior software engineering roles.
