Summary
🤩
Rockstar🎓
Top SchoolStefan Leszkiewicz is a pragmatic full-stack software engineer with 11 years of experience building web applications and automations across startups and large enterprises from Melbourne. He reliably ships production systems using modern JS front-ends (React, GraphQL) and serverless/AWS backends, and has hands-on experience with JVM microservices, Ruby on Rails, and data stores from DynamoDB to Neo4j. Stefan has repeatedly led greenfield projects and migrations—designing CQRS/event-sourced architectures and improving legacy Grails and Angular apps—so he balances new-idea velocity with maintainable, auditable systems. He values code quality and automation, scripting infrastructure with CloudFormation/Terraform and deployment pipelines for repeatable releases. Comfortable consulting across teams, he has turned complex data problems (custom Jira analytics, caching for long-running queries) into practical solutions. Outside of day-to-day work he’s passionate about open source and building tooling that reduces manual toil.
