Work history

Squid AI Remote Principal Software Engineer November 2022 – June 2025

Led backend and infrastructure engineering at an early-stage startup, leading development of a server-client library enabling direct database queries from front-end applications and architecting scalable, multi-cloud deployment pipelines.

Maintained and expanded the core Squid server and client library, allowing client-side applications like React to query databases directly without a middleware layer.
Built and deployed the company's cloud infrastructure from the ground up using AWS, later expanding to GCP and Azure with scalable, cloud-agnostic Kubernetes-based deployments.
Designed and implemented distributed locking mechanisms using Zookeeper to prevent deadlocks and improve backend reliability.
Migrated infrastructure provisioning from Terraform to CDK for Terraform (CDKTF), significantly reducing boilerplate code and improving maintainability across cloud environments.
Enabled horizontal scaling and seamless client-specific deployments through Kubernetes clusters, ensuring flexibility and cost-efficiency.
Played a central role in deployment strategy and infrastructure operations, evolving from backend contributor to sole infrastructure engineer, later leading as part of the on-call rotation team.
Supported high-profile clients, including the Chicago Bulls, by customizing cloud deployments and ensuring robust performance across platforms.
Guided new infrastructure engineers to establish internal best practices for cloud provisioning and deployment.

Rescale Remote Senior Software Engineer August 2020 – October 2022

Led engineering initiatives to streamline cloud-based high-performance computing (HPC) workflows, improve deployment efficiency, and enhance backend reliability for global enterprise clients.

Architected and deployed backend systems supporting HPC workloads, enabling engineers to run compute-intensive jobs on cloud clusters across Amazon Data Centers, including in Japan and Germany.
Led a project team of three engineers, responsible for scoping, planning, task delegation, and periodic technical syncs to ensure timely, high-quality delivery.
Rewrote a key startup pipeline to reduce server round-trips and eliminate inefficiencies, improving job initialization time by 15% and significantly reducing maintenance complexity.
Built integration tests that simulate real-world workloads in staging environments; configured key tests to block deployments if regressions or errors were detected.
Enhanced deployment reliability and release quality by instituting automated verification gates and staging validation prior to production pushes.
Collaborated across teams to define project scope, technical approaches, and infrastructure considerations, contributing to scalable architecture decisions.
Took ownership of full project lifecycle within a distributed engineering model, often serving as project-specific tech lead responsible for technical direction and coordination.

Instructure Remote Software Engineer, SRE March 2018 – January 2020

Led improvements to system reliability, CI/CD efficiency, and infrastructure scalability for a large-scale AWS-based learning platform, balancing real-time incident response with long-term infrastructure optimization.

Responded to critical on-call incidents and implemented preventative solutions, such as automating AWS capacity scaling to reduce future downtime.
Streamlined the continuous integration pipeline by consolidating multiple builds into a unified process, reducing build complexity and improving system resource efficiency.
Led the complex upgrade from Rails 4.2 to Rails 5.2, managing incremental changes and resolving deep compatibility issues to ensure system stability and future maintainability.
Improved deployment workflows and build system reliability, contributing to faster release cycles.
Enhanced AWS infrastructure across environments, ensuring availability, scalability, and cost-effectiveness.
Documented infrastructure health and contributed to internal engineering knowledge via technical blog posts.

Microsoft Bellevue, Washington Senior Software Engineer May 2016 – July 2017

Contributed to Bing’s local search team with a focus on improving observability, reliability, and test infrastructure for international search quality.

Developed a system to visualize test failures and deployment timelines, enabling faster root-cause analysis of regressions in live Bing environments across multiple languages and regions.
Improved quality assurance for Bing local search by building tools to correlate automated test failures with specific deployments, streamlining incident detection and resolution.
Collaborated cross-functionally with QA and deployment teams to strengthen test infrastructure.

Google New York City Site Reliability Engineer March 2014 – April 2016

Led deployments and system reliability initiatives for Chubby, Google’s internal distributed lock service, ensuring zero-downtime rollouts and proactive incident response across global data centers.

Adapted and extended an internal deployment framework to meet Chubby’s unique requirements, including designing a custom scheduler to automate and stage deployments across data centers.
Reduced manual effort for production pushes by transforming a weeks-long, hands-on release cycle into a streamlined, form-based trigger process, freeing up significant engineering hours.
Carried on-call pager responsibilities for global infrastructure, responding to and mitigating critical issues, though system stability typically ensured minimal alerts.
Wrote scripts to identify and assist clients running incompatible or broken versions of the Chubby client library, preventing outages during critical updates, even when addressing bugs like a divide-by-zero issue.
Improved monitoring and testing coverage by implementing comprehensive pre-, mid-, and post-deployment probes to validate rollout integrity and performance.
Contributed to the overall resiliency and trustworthiness of Google’s distributed systems by balancing hands-on reliability engineering with automation and proactive client support.

Google New York City Software Engineer, Backend August 2011 – March 2014

Built and maintained backend systems for DoubleClick’s ad tracking and reporting platform, optimizing large-scale data pipelines and supporting critical production environments.

Redesigned the reporting pipeline to enable downstream processes to begin immediately upon upstream completion, improving efficiency and ensuring data accuracy across millions of ad impressions and clicks.
Developed a synchronization library to replace fixed scheduling with dependency-based triggers, allowing precise, real-time handoff between pipeline stages and enabling customer migration to a newer reporting infrastructure.
Maintained and extended core components of the report generation system following the departure of the original developer, ensuring continuity and reliability.
Gained initial exposure to site reliability engineering through on-call support, including overnight shifts troubleshooting production systems in Google’s internal cloud.
