About me

Strategic, hands-on, and calm under pressure.

I’m a product-minded software engineer with a strong background in quality engineering, focused on developer tooling, IDE extensions, and automated testing. While my career started in QE, my work has consistently gone beyond testing — into designing, implementing, and maintaining production-grade tools and framework integrations.

Over the last several years, I’ve built extensions and tooling for Visual Studio Code, NetBeans, and Eclipse, combining TypeScript and Java with automated UI testing, CI/CD pipelines, and framework-level improvements. I’m most energized by problems where developer experience, reliability, and clarity matter — and where the right tooling helps teams move faster with confidence.

Master’s degree in Computer Science, complemented by international study experience across three universities, combining software engineering fundamentals with applied computer science.

          What I bring
          Reliability at scale – I help teams ship IDE tooling and extensions that stay stable
              under
              real-world usage.
Automation that pays off – I design test systems that reduce manual QA effort and catch
              regressions early.
Developer-first mindset – I build tools that fit naturally into developers’ workflows,
              not
              against them.
Bridge between QE and engineering – I translate quality concerns into actionable
              technical
              solutions.
Long-term maintainability – I care about clean architecture, observability, and
              sustainable test
              setups.

        

Experience

Teams I've helped move faster.

Software Quality Engineer

Red Hat | 2021 - 2025

In this role, I acted as the quality and tooling engineer across multiple developer-focused projects, with responsibilities extending beyond testing into development, architecture, and long-term ownership. In addition to my QE responsibilities, I brought hands-on developer experience—designing and implementing frameworks, IDE extensions, and internal tooling used in production. I designed and implemented automated UI testing strategies and improved CI/CD pipelines to increase reliability and release confidence. My work spanned Visual Studio Code, NetBeans, and Eclipse, using TypeScript and Java to build and maintain production-grade tooling. I collaborated closely with developers to reduce friction in everyday workflows and improve overall developer experience.

QE and tooling contributor for IDE extensions and framework integrations.
Designed and implemented automated UI test coverage for critical features, significantly improving stability.
Owned development of a NetBeans plugin published to the Plugin Portal (2600+ downloads).
Built VS Code tooling and extensions, including integrations for automated test execution.
Contributed to testing frameworks with stability and feature improvements.

Code Generator for ExTester

AI-assisted UI test generation for VS Code extensions

Experimental tooling that leverages large language models to generate, validate, and iteratively fix UI-level tests for VS Code extensions using the ExTester framework. The goal is to significantly reduce the time and effort required to create and maintain reliable UI tests.

Camel LSP Client for NetBeans

Language Server Protocol client for Apache Camel

Full-featured NetBeans plugin implementing a Language Server Protocol client for Apache Camel. I owned the project end-to-end, designed workarounds for NetBeans API limitations, and successfully published the plugin to the NetBeans Plugin Portal, where it reached thousands of users.
