What I'm looking for

I’m looking for a role where I can build and optimize SQL/ClickHouse systems, own database design and query performance, and work on ETL/data engineering. I want a team that values careful engineering and continuous learning.

I’m a Database Developer building and maintaining database structures and query workflows end to end—from requirements and design through development, testing, deployment, and maintenance. My core focus is T-SQL/SQL development, data modeling, and delivering reliable, well-performing database systems.

In recent work, I’ve been learning and certifying on ClickHouse while strengthening my coding skills through self-education (Python, Golang, Rust, and practice on platforms like lletcode.com and hackerrank.com). I also work with ETL-style data flows and performance optimization, identifying and resolving bottlenecks to improve query execution.

Earlier, I developed server-side and reporting logic using MS SQL Server and related database platforms, including stored procedure and function-based business logic. I worked on systems for insurance and banking use cases, and supported a CRM project with an approximate scale of ~200 tables and ~2K stored procedures.
