Hi, I'm Vova

I developed APIs and data pipelines, ran A/B tests, trained and deployed machine learning models, built full-stack apps and worked with OLAP systems. My stack included AWS (CDK, Lambda, S3, Kinesis, SQS, SNS and Step Functions), Grafana, Kubernetes and Next.js.

I guided a junior developer on an A/B testing management project, designing the system’s architecture and supporting their implementation and QA work.

I independently led and built a high-load replacement for the legacy pipeline that processed every image upload and updates to files, descriptions and other content. I also developed image-processing APIs that ran ML models at 5–8 requests per second. I developed and led an internal marketing tool that sent millions of notifications to users each week.

Our team worked on email spam detection for Cisco Talos, Cisco’s threat intelligence team.

I built a cached translation API designed to handle large volumes of email, translating message content to help the system identify spam.

I wrote extensive technical documentation and worked with Python, Kubernetes, PostgreSQL, Redis and email protocols.

I worked closely with traders to turn their market insights and hypotheses into algorithmic trading strategies. This involved collecting, processing and analyzing financial data, then translating trading ideas into code.

I also built chatbots and automated data pipelines using Kubeflow and AWS Step Functions to collect and prepare data for training machine learning models.

My stack included Python, Vue.js, AWS (S3, Lambda, EC2, Fargate, Step Functions), pandas, NumPy and Plotly.
