# Justin Calareso > Senior Software Engineer with a focus on highly available, distributed systems Location: New York, New York, United States Profile: https://flows.cv/justincalareso I'm a creative, pragmatic software engineer with broad expertise in backend development. With a wide range of experiences across the stack, slightly concentrating on microservices and other backends, I pride myself on my ability to analyze tradeoffs, work collaboratively, and constantly learn and pursue innovative concepts and techniques. At my current position as a member of the platform team at ObvioHealth, I develop our Kubernetes-based platform that the microservices from other teams run on top of. I led the redesign and implementation of our platform-level event service, used by all microservices to communicate with each other, as well as helped implement the Opentelemetry stack to allow us to monitor our running services. Guided by a healthy dose of curiosity, throughout my professional, academic, and recreational lives I’ve worked in data engineering, software design, requirements gathering as well as designed and coded in major languages including Python, Typescript, Java, SQL, and a little C. ## Work Experience ### Senior Software Engineer @ Glimpse Jan 2026 – Present | New York, NY ### Software Engineer @ Glimpse Jan 2024 – Jan 2026 | New York, New York, United States ### Software Engineer @ ObvioHealth Jan 2022 – Jan 2024 | New York, New York, United States Designed and implemented a highly optimized partitioning and filtering mechanism for the platform-wide event service, enabling support for multiple independent remote clinical trials with hundreds of thousands of users Architected robust tracing, metrics, logging, and profiling solutions using the industry-standard OpenTelemetry protocol, significantly improved our observability and troubleshooting capabilities Built a foundation library to be automatically injected into all of our running software and instrument the code, allowing our telemetry to work automatically, without requiring end user knowledge of telemetry Supported Kubernetes based platform running thousands of pods for our microservice architecture, including laying the foundation for custom autoscaling metrics Maintained developer portal and git-ops based CI/CD system to support rapid global development Updated and supported OAuth 2.0 authentication system for end users of clinical trials Investigated, triaged, and fixed live production issues across the software stack, including during a month-long stint on the site reliability engineering team and on an ad-hoc basis ### Data Engineer @ Redica Systems Jan 2021 – Jan 2022 | Seattle, Washington, United States Designed and built custom entity resolution pipeline for domestic and international pharmaceutical sites and organizations including gathering requirements from stakeholders across the company and building a system to provide human-quality entity resolution while minimize manual human review time Created ETL pipeline to load and serve models of FDA and international drug organization documents/data and track statistics over time Worked with a team of ~8 people to port backend mysql database to Snowflake Worked tightly with stakeholders to integrate changes into the data pipeline on production ### Software Engineer @ Magyk Software Jan 2020 – Jan 2021 Designed backend for client software, including partial integration with Kubernetes and EKS to allow for unlimited frontend scaling Created REST API with Neo4j and Postgres integration to integrate frontend with the databases Designed Postgres and Neo4j databases to read in streams of tweets in real-time and respond to frontend requests, optimizing for quick responses while still providing reasonably up-to-date data Migrated website frontend to docker then kubernetes on EKS ### Software Engineer Intern @ Magyk Software Jan 2018 – Jan 2019 Designed backend for timeclock software which tracks employees, the tasks they are working on, and other relevant data including designing the database, stored procedures, and REST API to allow frontend integration ## Education ### Bachelor’s Degree in Computer Science Rose-Hulman Institute of Technology Jan 2016 – Jan 2020 ### The Governor's Academy Jan 2012 – Jan 2016 ## Contact & Social - LinkedIn: https://linkedin.com/in/justin-calareso-ab348367 --- Source: https://flows.cv/justincalareso JSON Resume: https://flows.cv/justincalareso/resume.json Last updated: 2026-04-01
