• Co-maintainer and contributor to an open-source financial ledger system: enhanced the API, increased test coverage, and optimized performance through code profiling, ensuring real-time financial transaction tracking for applications.
• Maintainer and contributor to a virtual machine for executing Numscript , an open-source DSL simplifying complex financial modeling: improved the language with new features and optimized execution performance using code profiling.
• Led design and development of a new back-end webhooks microservice enhancing user interaction with the ledger : enabled users to receive useful notifications at any HTTP endpoint with a successful production deployment.

Technical environment: Go (microservices, monorepo), Gin, Chi, Bun, Cobra/Viper, Fx, PostgreSQL, Kafka, REST API, ANTLR, Unix, Docker, Docker-Compose, Kubernetes, AWS, ArgoCD, GitHub Actions, Codecov.

• Enhanced time-series data calculation engine and API: improved user experience, cache calculation and storage in InfluxDB, aggregations, interpolations, and performance optimizations using code profiling, resulting in more efficient data processing.
• Co-maintainer and contributor of Bow , an open-source Go library for dataframe manipulation: played a key role in the development of new features and its maintenance. This library is integral to the data processing engine in production, contributing to its success.
• Led the migration to InfluxDB v2: successfully managed a proof-of-concept of the migration to InfluxDB v2, which involved extensive codebase changes. This included refactoring, addressing breaking changes related to the new client and the transitioning to the new query language, and ensuring a seamless transition for the data processing system.
