Dmitrii Buchinschii

I’m a QA Engineer with 4 years of experience in FinTech and E-commerce, specializing in deep API/WebSocket testing, Shift-Left practices, and building QA processes from scratch. I focus on measurable impact—improving coverage, reducing defects, and making sprint planning more reliable.

At MacroGlide (May 2024–present), I built QA processes and an Agile/Scrum workflow from zero while delivering comprehensive manual testing across API (REST, WebSocket), Web, and iOS. I established a testing process that prevented critical defects (950+ API checks across smoke, regression, and integration), accelerated smoke testing 60x (1 hour to 1 minute via Postman/JS automation), and improved sprint planning accuracy by 75% by reducing average task size from 2–3 weeks to 2–3 days.

Previously at Niksoft Software (July 2022–February 2024), I owned functional and regression testing for Web and mobile (iOS/Android), including API testing and defect lifecycle management. I verified 200+ API endpoints in Postman (negative scenarios and boundary value analysis), designed 80+ logistics test cases to increase critical business logic coverage by 40%, and audited 150+ legacy test cases to remove duplication and align with QA best practices.

I’m expanding my automation expertise with Playwright/JS (in progress) and I’m committed to proactive quality—moving testing earlier with Shift-Left QA reviews before each sprint. I enjoy turning messy or incomplete testing efforts into structured, fast, and reliable QA that teams can trust.
