• NLU model development for voice bot intent classification: Extracted data from BigQuery. Prepared data using Pandas. Analyzed data for bot intent design. Assisted dataset annotation with ChatGPT. Trained and tested models using HuggingFace. Did ML tracking, conducted experiments and compared transformer-based models. Exported models to ONNX format. Utilized DVC for model versioning. • Implemented an end-to-end pipeline with DVC and Papermill for the NLU model, from dataset generation to model deployment. Established a feedback loop using Jira API, getting annotations from reported issues, checking for solved issues and updating those automatically, sending reports to Slack. This automation reduced the manual work of two–three days to ze

Data Engineer

Vindow

Aug 2020 - Sep 2021 (1 year 2 months)

• Designed and developed a serverless data acquisition and model training pipeline on AWS using Step Functions, Lambda, ECS, S3, MongoDB, CDK — I did it almost entirely in TypeScript. It replaced a single process that used to run on AWS EKS and took ~10 hours to complete. Due costs involved the company updated its data/model monthly; with the new pipeline this was done almost on a daily basis, as it just needed around half an hour to finish. • Developed several data services and exposed them in a Node.js web application. One of them was a document recognizer based on AWS Textract. Another was the retrieval side of a recommendation system in Elasticsearch.

Electriq Power

Jul 2020 - Dec 2022 (2 years 6 months)

• Management and mentorship of the data team. I created a team of 3 junior, 1 semi-senior devs from the ground up. • Designed and leaded the development of a real-time IoT data ingest pipeline, data lake and APIs in GCP using Pub/Sub, Cloud Run, Cloud Functions, Dataflow, InfluxDB, FastAPI. This pipeline replaced a legacy process that run in a single VM. Going serverless provided redundancy and robustness to the pipeline. In addition, the improved data schema and APIs reduced some queries from 60 seconds to 2 seconds.
