Developed an in-house Serverless backend (using Golang) and SPA frontend (with Angular/Typescript) to automate SLO workflow definition, calculation, and tracking of Error Budgets across >2,000 teams using NewRelic Agents & NRQL, OpenTelemetry, and Snowflake data, fostering an enterprise-wide behavioral paradigm shift towards achieving more aggressive milestones.

Served as Development Lead during my tenure to complete one or more concurrent strategic functional & non-functional CMS improvement initiatives, helping to bolster team’s reputation and meet corporate goals.Performed strategic refactoring to increase componentization and testability by creating “code seams” along which to introduce test coverage across four backend codebases by an average of 25%, resulting in greater stability, confidence and developer productivity.Optimized database access plans after surveying production query and update persistence behaviors for the most critical two of the CMS services, resulting in increased throughput by 20-50%.Reduced frequency and MTTR of “sev 1” issues (e.g., stemming from NPE, OOM or API drift) by 30% through the above improvements, and exposed custom metrics using NewRelic Agent while improving dashboards using NRQL.Solved several elusive, recurring issues leading to on-call alerts, including:* Thundering herd scenarios resulting from spikes in demand, causing platform outages* Race conditions causing integrity / synchronization failuresImproved Maintainability of Legacy Microservice Mesh by:* Leveraging logging enhacements and custom instrumentation to trace data stream flows* Analyzing and documenting end-to-end flows using UMLImproved Observability by:* Creating source controlled templates for NewRelic dashboards across environments* Leading initiative to migrate from NewRelic to DataDogImproved Team Development Workflows by:* Reducing onboarding time for new developers through mentorship, documentation & peer sessions* Advocating TDD practices and establishing increased minimum code coverage and linting standards

Embraced several paid and unpaid opportunities in the first year of the COVID epidemic to learn new skills and be with my family.Some relevant skills I learned during this period:- Java Play Framework- Recent improvements in JDK's Garbage Collector and other improvements- WordPress- The "R" Language- Several online courses related to the AWS & GCP Cloud- Composition and home production of family movies & music (DAW, DVES)

As a key contributor of Data Integrations team, tasked with reliably ingesting data from corporate customers, helped decompose a monolith into manageable and extendable services within a Kubernetes cluster, running within the AWS cloud. Designed and implemented services to:- Fetch data from external endpoints according to scheduled or ad-hoc queries- Inspect and de-multiplex incoming data, enriched with validation results per business rules- Extract and "replay" historical data according to query criteriaImplemented multi-sourced (push events, pull ETLs) data pipeline with gRPC normalization schemata and Kafka / KTable backbone to deliver high throughput customer streams to Apache Spark and other consumers.Engineered a Groovy script-based plug-in architecture, empowering field technicians to implement site-specific ETL customizations and resolve issues independently. This enhancement increased core team availability by 50%, facilitating an accelerated schedule for roadmap functionality improvements.Utilized Docker, Minikube (Kubernetes), Terraform and Helm Charts to streamline handoff from local development & component-level testing to the Jenkins-based CI/CD integration tests & production deployments.Interviewed and on-boarded new team members.Coordinated and supervised off-shore development.Introduced Rollbar logging to help quickly triage issues.
