What I'm looking for

I’m open to discussing potential opportunities and collaboration.

At Bolt, I developed backend services for analyzing courier movements and routes, turning GPS coordinates and delivery events into data for internal analytics tools. I contributed to an internal platform that made delivery processes analyzable from order assignment through completion.

I moved computationally intensive GPS processing and analytical view generation into an asynchronous Kafka-based pipeline, with safe handling of message redelivery. By optimizing SQL, indexes, data structures, and pre-aggregation, I improved selected analytical queries and APIs by 30–100%.

Before Bolt, I developed REST APIs and backend logic for G-Core Labs’ internal cloud administration panel, improving workflows and query performance. I’m open to discussing potential opportunities and collaboration.
