About me

Intro

Senior Software Engineer with 7+ years of experience in backend development using Java, Kotlin, and Spring Boot. I specialize in cutting costs by optimizing system performance, architecture, and delivery pipelines. Some examples of my results include: โ€ข ๐—”๐—ฐ๐—ฐ๐—ฒ๐—น๐—ฒ๐—ฟ๐—ฎ๐˜๐—ฒ๐—ฑ ๐—ณ๐—ฒ๐—ฎ๐˜๐˜‚๐—ฟ๐—ฒ ๐—ฑ๐—ฒ๐—น๐—ถ๐˜ƒ๐—ฒ๐—ฟ๐˜† ๐—ฏ๐˜† ๐Ÿฐ๐˜… (2 months โ†’ 15 days) by redesigning feature solutions and improving efficiency in a supply chain audit platform. โ€ข ๐—•๐—ผ๐—ผ๐˜€๐˜๐—ฒ๐—ฑ ๐˜€๐˜†๐˜€๐˜๐—ฒ๐—บ ๐—น๐—ผ๐—ฎ๐—ฑ ๐˜€๐—ฝ๐—ฒ๐—ฒ๐—ฑ ๐Ÿญ๐Ÿฌ๐˜… and eliminated timeouts by optimizing API responses through caching, multithreading, and filter tuning. โ€ข ๐—–๐˜‚๐˜ ๐—ฐ๐—ผ๐—ฑ๐—ฒ๐—ฏ๐—ฎ๐˜€๐—ฒ ๐—ฏ๐˜† ๐Ÿฏ๐˜… and simplified future integrations by refactoring legacy services and centralizing translation systems, reducing translation tasks from 20 to 2. I also enabled full data sync during migration from monolith to microservices architecture using Kafka and RabbitMQ, directly improving user experience and system scalability. Earlier, I supported the integration with Google and Microsoft APIs at Kaseya, enabling automated backups for ๐Ÿฎ.๐Ÿฑ๐— + users. I thrive in cross-functional teams, enjoy mentoring junior devs, and contribute to long-term team stabilityโ€”recently onboarded a new dev who successfully passed probation and stayed on the team.

Accelerated feature development time by 4x (from 2 month to 15 days) by taking initiative and proposing an optimized approach, enabling users to access the functionality within a month. Simplified future 3rd party integrations and taking initiative in code refactoring and code clarity by standardized legacy services and reducing the codebase by 3x as the result. Mentored two junior engineers and successfully onboarded one new team member who passed the probation period and remained with the company, contributing to team stability and growth. Sped up page loading by 10x (from 10s to 1s) and prevented timeouts by optimizing API response time through caching, multithreading, and filter refinement, enhancing system efficiency and user experience. Achieved 99.9% data synchronization by migrating a legacy monolithic platform to microservices architecture using Kafka and RabbitMQ, developing features from scratch and enhancing user experience. Enabled faster development by reducing translation component tasks from 20 to 2 through creation of a core library and centralization of translation functionality using caching and CDN.
