Available to hire
I’m Alexander Zdanowicz, a senior-level software engineer with nearly 6 years of experience in cross-platform development, cloud infrastructure, and event-driven architectures. I learn quickly, take ownership of outcomes, thrive as both a team player and a leader, and I enjoy turning complex problems into straightforward, scalable solutions.
I’m passionate about delivering robust software that creates real business value—whether that’s architecting data pipelines, guiding deployments with zero-downtime migrations, or quickly debugging production outages. I love leveraging modern tools and AI to simplify workflows and accelerate delivery.
