Principal Software Engineer, Tech Lead at Pepper Pay

May 1, 2025 - May 1, 2026

Architected and delivered a multi-tenant payments platform using Python (Django) and PostgreSQL on AWS. Improved peak throughput by ~35% via query tuning, Redis caching, and async processing with SQS. Translated stakeholder requirements into technical roadmaps (milestones, risks, dependencies), aligned API contracts, evolved data models, and drove rollout planning. Led client-facing discovery and delivery meetings and produced system design artifacts such as sequence diagrams, ADRs, and capacity plans. Drove consensus on microservices boundaries and integration patterns. Built responsive admin and customer portals with React/TypeScript integrated with Django REST endpoints, reducing manual support steps by ~25%. Implemented CI/CD with GitHub Actions and Docker deployments on ECS, cutting deployment time from ~45 minutes to under 10 minutes. Introduced Terraform for standardized environment provisioning and reduced configuration drift by ~40%. Established observability with OpenTeleme

Senior Software Engineer at Care.com

April 1, 2024 - April 1, 2025

Developed and maintained high-traffic full-stack features using Python (Flask) services and React UI components, improving page performance by ~18% through API consolidation and client-side rendering optimizations. Designed and implemented scalable REST APIs with PostgreSQL and Redis caching, reducing p95 latency by ~25% for key user journeys. Partnered with product and stakeholders to convert business requirements into technical plans, including phased rollouts, instrumentation, and backward-compatible API changes. Improved reliability with pytest integration tests and contract testing for service boundaries, increasing CI signal quality and reducing regressions. Implemented event-driven workflows with Kafka for asynchronous processing and auditability, improving resilience during traffic spikes. Hardened authentication and authorization using OAuth2/OIDC patterns and least-privilege access controls; contributed to OWASP-focused security reviews.

Software Engineer at RetailMeNot

June 1, 2018 - June 1, 2023

Built and evolved backend services in Python (Django/Flask) supporting high-volume promotions and content workflows, backed by PostgreSQL and Elasticsearch for search use cases. Delivered customer-facing UI enhancements with React and TypeScript, collaborating with design to improve accessibility and reduce UI defects using Jest and React Testing Library coverage. Implemented CI/CD pipelines (Jenkins/GitHub Actions) with automated testing and quality gates to increase release frequency while reducing production incidents. Optimized cloud costs and performance on AWS via autoscaling, Redis caching, and compute right-sizing, contributing to measurable monthly spend reductions. Instrumented services with metrics, logs, and tracing using CloudWatch and distributed tracing patterns to improve incident response and capacity planning.

Software Engineer at Wells Fargo

November 1, 2015 - May 1, 2018

Developed secure internal web applications and APIs using Python services and relational databases (including Oracle/PostgreSQL) supporting regulated workflows and audit requirements. Implemented automated builds and deployments with CI tooling and Docker to improve consistency across environments and reduce manual release steps. Strengthened application security by applying OWASP best practices, improving input validation, and tightening access controls with role-based authorization. Created monitoring and alerting with platform tooling and structured logging to improve operational visibility and reduce time to detect issues.
