Senior Product Engineer (TypeScript / React / Node.js)

Product Thinking • Systems Thinking • Craft-Driven

Product engineer with 15+ years of experience building for the web. I work end-to-end — from understanding problems to shipping thoughtful, well-crafted experiences.

Strong foundation in backend systems and architecture, combined with a growing focus on frontend craft, interaction quality, and design engineering.

Experience in technical leadership, bringing strong ownership, communication, and alignment skills, while choosing to stay hands-on.

I care about speed, iteration, and making thoughtful tradeoffs to deliver real impact.

Selected Contributions

High-Scale Async Pricing Ingestion Platform

• Reduced processing time for 1M pricing records from >24h to ~30 minutes and lowered compute costs by ~10× by redesigning the pricing ingestion pipeline.
• Led discovery and requirements definition, establishing processing SLAs, consistency guarantees, and operational constraints for large partner price list imports.
• Designed a distributed ingestion architecture handling ~10M pricing records/day under burst-heavy workloads.
• Implemented a serverless processing pipeline using AWS Lambda, Event Bridge and API Gateway to dynamically scale with ingestion bursts.

Order Platform Team Creation & Shared Services Architecture

• Identified growing architectural fragmentation and duplicated implementations across multiple order-related product teams.
• Proposed and led the creation of a dedicated Order Platform team to centralize core order domain capabilities.
• Designed shared services and platform components used by multiple stream-aligned teams, reducing duplication and ensuring consistent behavior across products.
• Consolidated domain expertise and enabled teams to reuse common functionality, improving development speed and long-term maintainability.
• Staffed the team by hiring and onboarding engineers both internally and externally.

Search Platform Ownership & Strategic Reset

• Identified systemic ownership gaps in the core Search service powering critical product flows.
• Surfaced architectural drift: duplicated solutions, ad-hoc workarounds, data inconsistencies, and increasing latency.
• Highlighted operational and product risks caused by unclear ownership and limited Elasticsearch expertise.
• Identified domain boundaries between search and adjacent domains.
• Advocated for consolidation of efforts and elevation of Search as a strategic platform concern.
• Established clear ownership boundaries and initiated a product-oriented long-term vision between senior engineers and PMs.

Event-Driven Subsystem Communication Standards

• Defined shared standards for inter-service communication across subsystems.
• Introduced event-driven patterns using AWS EventBridge.
• Clarified when to prefer events over direct service-to-service communication.
• Improved decoupling, scalability, and long-term system evolution.

Order Management System Architecture

• Architected and owned a resilient Order Management system handling thousands of daily transactions with near-zero tolerance for failure.
• Designed bounded contexts for order lifecycles, notifications, and inventory management.
• Exposed APIs to internal platform, third-party integrations, and partner systems.
• Designed fault-tolerant retry mechanisms ensuring EDI transactions completed despite transient integration failures (APIs, FTP, email).
• Reduced operational incidents to near-zero downtime, eliminating manual intervention at scale.

Declarative Validation Framework (Pre-Ecosystem Maturity)

• Designed and implemented a declarative, composable validation framework for API input and domain constraints before mature TypeScript validation libraries were widely available.
• Built a strongly typed API leveraging advanced TypeScript generics and functional composition patterns.
• Adopted across multiple backend services and maintained in production for several years.
• Later migrated to ecosystem-standard tooling once it became the better long-term fit.

Engineering Quality Standards

• Authored and introduced a Testing Manifesto to standardize testing vocabulary, tooling, and expectations across engineering.
• Elevated shared quality standards by defining guiding principles, documenting practical guidelines, and partnering closely with teams to drive adoption.
