Software Engineer II - Cloudflare
• Automated generation and validation of new customer
networking configurations, eliminating manual errors,
saving 400+ hours, and reducing onboarding time by 16%.
• Spearheaded the migration of customer edge networking
configurations (GRE/IPsec tunnels, Interconnects) from a
monolithic YAML repository into a normalized SQL data
model, reducing config duplication by 50% and cutting
configuration-related incidents by 85%.
• Designed and built scalable real-time data pipelines
using Go, Kafka, and ClickHouse to process per-datacenter
GRE/IPsec tunnel health, enabling Grafana dashboards with
datacenter-level visibility.
Software Engineer II - Cox Communications
• Led a team of 5 engineers to build an internal
monitoring and analytics platform leveraging AWS, Python,
and Kubernetes, driving over 8-figure savings by
deprecating a third-party tool's costs.
• Designed and built scalable ETL pipelines using PySpark
and Kafka to process and enrich 1B+ daily real-time router
alarms, filtering noise and appending customer metadata to
enable intelligent alerting.
• Implemented a proactive incident detection and automated
ticketing pipeline, reducing customer-reported issues by
45% and increasing CSAT by 12%.
Software Engineer - HubSpot
• Reduced log storage costs by seven figures and increased
retention from 180 to 460 days by converting JSON logs to
ORC and optimizing S3 storage with AWS Athena.
• Built end-to-end log, metric, and trace correlation at
scale using trace/span IDs and exemplars, reducing
root-cause analysis time by 50%.
• Automated OpenTelemetry instrumentation for core
internal libraries, feeding 10M+ traces daily into Tempo
and reducing debugging time across services.
Tech Lead - PACI
• Redesigned Python and Golang APIs using OpenAPI specs
with auto-generated TypeScript clients, improving
cross-team collaboration and reducing integration errors.
• Spearheaded the migration of the entire frontend
codebase from JavaScript to TypeScript, improving type
safety and leading to a 35% reduction in bugs.
• Led architectural design and deployment using
Kubernetes, Docker, PostgreSQL, and AWS, resulting in zero
downtime during peak events and a 3x improvement in
deployment reliability.
Software Engineer Intern - Amazon Prime Video
• Designed API contracts and APIs using OpenAPI, AWS API
Gateway, and Java which increased content delivery on
Prime Video Sports from 70 to 150+ Live Events per day.
• Engineered a client library in Python and Java that
seamlessly integrated our APIs, reducing integration time
from 16 hours to 1 hour for external broadcast partners.
• Deployed and documented the client library with usage
examples and code samples using AWS Amplify, HTML, CSS,
and TypeScript.
