Egor Kuzmin
Full Stack Engineer
Summary
Full‑stack engineer building modern web products with Java/Spring or Python backends and Next.js/TypeScript frontends on AWS. I use AI‑assisted coding to accelerate delivery (scaffolding, refactoring, tests, docs) while keeping quality high through code review, CI/CD, and strong test coverage. Recently shipped GenAI search (Bedrock + embeddings + OpenSearch), production microservices on ECS, and enterprise modernization in pharma/finance domains.

Lead Software Engineer
November 2022 – Present
Worked across multiple enterprise projects (pharmaceutical operations, GenAI search, and internal platform services) focused on modernization, performance, and reliability.
- Delivered multiple enterprise projects as a full‑stack engineer (Java/Spring microservices + Next.js/TypeScript UI) on AWS, from design to production support.
- Built GenAI search with AWS Bedrock (Titan embeddings) + OpenSearch/S3, improving relevance via prompt/RAG tuning and evaluation-driven iteration.
- Designed and shipped backend microservices with Java 21 + Spring Boot 3, containerized with Docker and deployed to AWS ECS via CI/CD.
- Developed a full‑stack web app (Next.js/TypeScript + Java/Spring) with secure auth (NextAuth), Kafka/Kafka Streams integrations, and OpenAPI documentation.
- Modernized a critical pharma operations system: modularized components, removed performance bottlenecks, and improved reliability through automated testing and CI pipelines.
- Practiced AI‑assisted coding to speed up scaffolding, refactoring, test generation, and documentation; validated outputs with reviews, static analysis, and automated integration tests (up to 95% coverage on key services).
