Profile

Technical depth. Product perspective.

My work starts with the technical problem and follows the product into operation. I design architectures, write and review code, shape cloud and observability, and—when the context calls for it—coordinate people, priorities, and risk to turn decisions into reliable software.

01

End-to-end delivery

Backend, web, mobile, integrations, and infrastructure followed through to production.

02

Production & reliability

Performance, observability, security, and operations treated as part of the product.

03

Applied leadership

Technical direction, quality standards, and team coordination grounded in engineering context.

Practice

From architecture to operations.

My experience combines implementation depth, systems architecture, and accountability for what happens after deployment.

Backend & platforms

High-throughput APIs, integrations, data, and services designed for real load.

Web, mobile & media

Next.js, Kotlin, and connected-device experiences, from interface to streaming.

Cloud, reliability & operations

AWS, GCP, observability, security, CI/CD, and operational response.

Architecture, technical leadership & IT management

Technical decisions, quality, priorities, and teams aligned with product context.

Career

Growing without leaving the code behind.

Since 2022, I have moved from full-stack development through technology management into senior backend engineering. I bring architecture, cloud, and operations into hands-on coding.
