About

Professional summary

I am an Application Support Engineer (L3) and Sustaining Engineer with more than three years of commercial experience supporting, troubleshooting, and maintaining large-scale ERP and SaaS applications.

I specialize in C# and .NET backend environments, with experience debugging complex production issues, conducting root cause analysis, and delivering reliable hotfixes for business-critical systems.

I have strong experience with SQL Server, Oracle, T-SQL, and PL/SQL. I investigate slow queries, validate data, optimize database operations, and help preserve data integrity across enterprise applications.

I work with REST APIs, JSON, logs, integrations, and legacy systems. My approach combines technical investigation, clear written communication, incident documentation, and practical corrective actions.

I have supported remote Agile and Scrum teams, collaborating with developers, business analysts, and other stakeholders to reduce downtime and improve application stability.

I am continuing to develop my backend and integration troubleshooting skills through independent study focused on API behavior, error handling, data validation, and communicating technical solutions in English.
