I’m a senior backend and platform engineer with 14 years of experience designing, building, and operating distributed systems, cloud infrastructure, and full-stack applications. I specialize in Elixir/Phoenix and PostgreSQL, and I also bring strong experience with React and TypeScript, plus additional background in Java, Go, Ruby on Rails, and Qt—always with a focus on reliability, performance, and production readiness. I’ve worked across real-time and REST-based distributed services, observability, troubleshooting, and performance optimization in environments that include robotics and computer vision, embedded systems, and developer platform tooling. I’m hands-on with AWS/GCP, Docker, Kubernetes, and CI/CD, and I enjoy turning complex operational needs into stable services, efficient workflows, and measurable improvements in deployment speed, uptime, and engineering productivity.…I’m a senior backend and platform engineer with 14 years of experience designing, building, and operating distributed systems, cloud infrastructure, and full-stack applications.

Work Experience

Senior Full-Stack / Platform Engineer at Serve Robotics

March 1, 2021 - Present

Architected Elixir-based fleet telemetry services for collecting and processing robot status updates, improving operational visibility across production robotics environments. Built services for efficient robot-to-cloud communication to help engineers identify connectivity failures and runtime issues. Developed React and TypeScript operational dashboards that unified robot health, delivery exceptions, and operational information. Standardized deployment workflows using Docker, Kubernetes, and CI/CD, reducing release preparation time from ~45 minutes to ~20 minutes, and improved observability and reliability by adding structured logging and health checks across Elixir/Python services (reducing incident detection time from ~15 minutes to ~5 minutes). Worked across backend services, operational tooling, cloud infrastructure, and production troubleshooting in distributed robotics environments.

Full-Stack Engineer at V7

August 1, 2018 - August 31, 2018

Developed Elixir/Phoenix backend workflows for annotation-task assignment, review tracking, and background processing used in computer-vision data operations. Optimized PostgreSQL queries and indexes for image-dataset browsing, reducing average response times from ~800 ms to ~350 ms. Built React/TypeScript annotation-review interfaces with keyboard-driven workflows and batch actions to streamline repetitive review operations. Automated dataset validation using Python and Docker to detect missing labels and invalid metadata before downstream workflows, and improved large dataset imports using Elixir background processing with batch jobs of ~10,000 images.

Full-Stack / DevOps Engineer at CloudBees

August 1, 2015 - August 31, 2015

Built and standardized Jenkins CI/CD pipelines supporting Java and Go services across 12 repositories, improving consistency of build and test workflows. Containerized local development and test environments using Docker and Linux to simplify setup for engineers. Integrated Ruby on Rails backend components and React interfaces into internal build-status and release tooling. Supported AWS-based build infrastructure including worker provisioning, cleanup, and operational automation, and introduced reusable Jenkins pipeline stages and dependency caching to reduce average build duration from ~18 minutes to ~12 minutes. Worked across Java, Go, Ruby on Rails, React, AWS, Docker, Linux, and Jenkins.

Back-End / Systems Engineer at Ispirata Romania

June 1, 2012 - June 30, 2012

Developed a C application for embedded Linux device management including initialization, configuration, and diagnostic functionality. Improved Linux networking and connection logic for devices operating across unstable or interrupted connections. Built Python regression tests covering 40 device-configuration scenarios to improve release validation repeatability. Extended REST APIs to support device configuration, diagnostics, and batch operations, and optimized memory usage in C through buffer reuse and allocation improvements for resource-constrained hardware. Built hands-on experience across Linux, networking, REST APIs, testing, and systems performance.
