• Position: Lead Software Engineer
• Since: July 2021
• Until: December 2025

I designed and developed high-load microservices using Kotlin and Ktor, focusing on scalable and reliable system architecture.

I led a cross-functional engineering team consisting of frontend, backend, and QA specialists, coordinating development across disciplines and ensuring timely delivery of complex features.

My work included building a no-code system for integrating external data sources and constructing data pipelines, with execution powered by SQL both locally and in the cloud. I also implemented a paid API Gateway, including cost-aware services, and designed a subscription and token-based access system that enabled secure API usage without requiring users to manage their own service keys.

In addition, I developed a cloud-based server that allowed multiple users to collaboratively edit data pipelines in real time. I was responsible for designing, maintaining, and scaling the AWS infrastructure, fully managed through Terraform.

Beyond technical leadership, I handled hiring, budget planning, and ongoing people management, including regular one-on-one meetings.

• Position: Lead Software Engineer
• Since: November 2017
• Until: July 2021

As the lead software engineer, I designed and built a cloud-based data platform from the ground up, focusing on high-load, scalable architecture. I developed backend microservices using Kotlin and Ktor, and was responsible for the overall system design and technical direction.

I led a cross-functional engineering team of frontend, backend, and QA engineers, coordinating delivery across disciplines and ensuring alignment between technical implementation and product goals.

I built a no-code system for integrating external data sources and constructing data pipelines, with execution powered by SQL both locally and in the cloud. I implemented a paid API Gateway, including cost-aware services, and designed a subscription- and token-based access model that enabled secure API usage without requiring users to manage their own service keys.

In addition, I developed a cloud-based collaboration server that allowed multiple users to edit data pipelines concurrently. I designed, deployed, and maintained the AWS infrastructure, fully managed with Terraform.

Beyond hands-on engineering, I was responsible for hiring, budget planning, and people management, including regular one-on-one meetings, as well as code reviews, technical design discussions, and delivery planning.

• Position: Remote Full-Stack Developer
• Since: May 2019
• Until: February 2020

As a remote web developer at BIARUM, I contributed to the development of new features for the Benefit Enrollment module, working on a modern web architecture built with React, GraphQL, Node.js, AWS Lambda, and the Serverless framework.

I played a key role in migrating the legacy system from Unibasic, Scala, Unidata, and AngularJS to the new technology stack. This involved analyzing and restructuring complex enrollment forms to ensure data integrity and functional parity throughout the migration process.

I collaborated with a distributed team of product owners, a scrum master, QA engineers, a team lead, and UI/UX designers, participating in daily remote stand-ups and sprint ceremonies. The team followed the Scrum methodology, with task tracking and delivery managed through Atlassian Jira.

• Position: Full-Stack Developer
• Since: July 2017
• Until: July 2021

As a full-stack web developer at Biarum, I worked on healthcare and traffic data projects, building and refactoring systems using Java, Spring Boot, Angular, PostgreSQL, Redis, and PostGIS. I implemented automated PPTX report generation with Apache POI and developed map-based algorithms for working with geospatial data.

In addition to development, I set up and maintained server environments across multiple operating systems, supported CI/CD with TeamCity, ensured code quality with SonarQube, and contributed through code reviews, technical consulting, and conducting technical interviews.

• Position: Intern Java Developer
• Since: July 2016
• Until: July 2017

As a web development intern at Siemens, I worked on both backend and frontend development for two enterprise applications using Java, Spring, AngularJS, and PostgreSQL. One project focused on rail traffic systems, where I rewrote a heuristic algorithm from Python to Java, while the other involved designing power network planning software from scratch.

I gained hands-on experience with debugging, testing, and CI/CD by setting up and integrating Jenkins and TeamCity, collaborated using Git, and worked within Scrum with elements of XP, using Redmine for project tracking.
