- Implemented asynchronous index construction, which reduced application launch time by 90% on storage with a lot of video data.
- Engineered snapshot creation from uncommitted video in constant memory, enabling customers to integrate video analysis over a live video stream without an increase in RAM usage.
- Designed and executed a successful storage component refactoring, decoupling storage itself, replication and web-service components. This allowed for low cost implementations of other types of storage.
- Implemented an AWS S3 storage type with on-flight index construction, which allowed customers to attach thousands of cameras and utilize video storage with terabytes of data.

- Developed a new logging system with advanced contexts and tracing in a structured format, to establish an in-code observability system with Prometheus and Grafana integration. This initiative resulted in detecting database pool abuse, identifying memory leaks, solving indexing problems for a big customer, and an accelerated incident investigations process; enabling a 20% time reduction.
- Designed and implemented the core end-to-end tests infrastructure, leading to the establishment of a dedicated testing team and a 50% reduction in manual test cases.
- Acted as a team lead with a focus on fostering tight cross-functional collaboration – introduced a clear and structured meetings process, which enabled the team to address important issues within the allotted time, saving about an hour per week per team member.
- Designed a policy that improved the linearity and readability of our Git history, reduced the time spent on conflict resolution and prevented the loss of hotfixes in sub-branches.

- Updated the Haskell Algorand open-source SDK to support a new breaking version of the indexer, decreased indexer connection latencies by 15%.
- Optimized smart contract interaction, achieving a 30% reduction in failed attempts during token swaps. This enhancement provides users with a more reliable method, resulting in significant savings on commission fees.
- Acquired experience with a static type system and engaged in type-level programming. Played a key role in investigating and resolving compilation memory leaks related to types specialization.
