- Built backend services to collect, normalize, and store large datasets from web sources - Designed ETL‑like pipelines converting unstructured web data into structured SQL datasets - Developed Python‑based document processing service for automated proofreading - Improved backend performance and reliability through asynchronous processing and multithreading - Collaborated with business stakeholders to translate data needs into technical solutions Key project: Stream Video ML Backend Service (AWS, FastAPI, Docker) - Designed and implemented a backend service for real-time RTSP video ingestion, preprocessing, and ML inference - Exposed REST and Server-Sent Events (SSE) APIs for live predictions and system health - Deployed containerized services to AWS ECS Fargate with CI/CD pipelines (GitHub Actions, ECR) - Implemented observability using CloudWatch Logs and structured JSON metrics - Built data capture pipelines to store inference datasets for model retraining - Provided Terraform templates and deployment runbooks for AWS infrastructure

Contributed backend APIs for an RTSP video ML service (FastAPI: health, predict, SSE), integrated preprocessing/inference pipeline, and containerized the runtime with Docker. Implemented CI/CD automation in GitHub Actions to build and push images to ECR and deploy to ECS Fargate, with CloudWatch logging/metrics for runtime visibility. Integrated AI APIs for data enrichment and intelligent processing 1. Projects for scraping business catalogs. http://webscraping.pro/business-directories-scrape-tips-tricks/ 2. Development of a cloud service for launching scrapers. PHP, JAVA. 3. Xing companies scrape.
