✔ In collaboration with the Data-Science team, turned a Proof-of-Concept into an "AI"-powered analytics tool that automated manual work and increased the company’s response speed to regulatory violations. ✔ Isolated restart-sensitive code for working with media data into a microservice, reducing unnecessary deployments and improving the stability of the solution in the initial stages. Later, I used SQS and changed the service implementation without changing the API. ✔ Introduced basic development standards, turning unproductive discussions into a process of suggestions, voting, and decision-making. ✔ Implemented CI/CD pipelines for code checking and running automated tests to identify errors at an early stage, which allowed us to reduce manual testing time in the staging environment. ✖ I was unable to support a new project that was the result of uncontrolled vibe-coding.

✔ Participated in development of AI-solution for marketers. ✔ Implemented role-based access control to AI-assistants.

Simplified testing by making fixtures (pytest) complementary to each other. ✔ Implemented a video communication service that supports Full Mesh and SFU (Selective Forward Unit) topologies using WebRTC. ✔ Implemented a live queue system for video-appointments with a doctor.

✔ Implemented data indexing and full-text search using OpenSearch (a fork of ElasticSearch). Made indexing for changes in the database using MongoDB ChangeStreams, practically without service code modification. ✔ Implemented a service for PDF reports generation using Playwright. ✔ Implemented a service for sending SMS, email and push notifications using AWS SNS and AWS SES.

✔ Implemented validation and cutting of thumbnails of images uploaded to AWS S3. ✔ Implemented the CSV reports of performed medical tests.

✔ Maintained legacy. ✔ Participated in rewriting the project from Python 2 to Python 3. ✔ Implemented a state machine for taking cognitive tests. ✔ Implemented a service for sending push notifications via AWS SNS.

✔ Implemented a service for information recognition from photos of PAN and Aadhar cards, account statements of HDFC and KOTAK banks. ✔ I created a voting system with complex scoring logic for a service for exchanging opinions on controversial topics. ✔ Was blocked from Upwork due to a duplicate account left at my previous company.

✔ Maintained internal tools for scraping information from LinkedIn and Head Hunter. ✔ Implemented asynchronous scraping of websites in a pool of browsers. ✔ Implemented CSV reports for a system collecting data from smart utility meters. ✔ Instead of working, I decided to finish university.

✔ Fixed a project for monitoring the prices of products from Amazon. Adapted the parser to the new markup, fixed search of HTTPS proxy. ✔ Implemented a service between a system collecting meteorological data from railway stations and a website that displays them on a map.
