Ренат Захарьев

At Балка-Фара и Дейра-авто, I developed and maintained eight Python reporting and analytics processes, bringing together ERP/1C, API, spreadsheet, bank, logistics, and marketplace data. My monthly profitability and month-end automation cut the reporting cycle from two to three working days to two hours.

I also managed website bug fixes, feature development, and delivery through Codex. More than 600 improvements contributed to a 0.07% increase in order conversion and 8.5% growth in turnover.

For Job Match Assistant / Auto Vacancy Search, I developed a FastAPI application that matches vacancy requirements with resumes using an LLM. I implemented REST endpoints and Pydantic validation, and added privacy safeguards to anonymize resumes before database storage.

On my Trading Bot / Bitcoin data and ML pipeline, I developed data preparation for feature generation and trading-action model training. I optimized the pipeline with Dask, making annual dataset preparation about 90 times faster, and created an asynchronous Bitcoin blockchain parser.
