Professional Experience

Founder|Beginner Work Inc.

San Diego, CA|Mar 2026 – Jul 2026

  • Built and launched a fundraising pitch simulator (React/Next.js) as sole founder; owned product discovery, architecture, and GTM. Validated demand through 92 in-person conversations (including 5 VCs) and 28 early users.
  • Wound down in Jul 2026 rather than raise. Personal runway could not cover a full fundraising cycle; returned to Engineering Manager roles.

Software Engineering Manager (L7), Merchant Advocacy|Affirm

San Diego, CA (Remote)|Mar 2025 – Feb 2026

  • Scope:Managed 6 software engineers as direct reports, partnering with Product, Design, and Content; owned affirm.com and Merchant Portal (React, TypeScript) serving SMB/ecommerce-integration merchants, including native onboarding onto Affirm’s payment method via API.
  • affirm.com revamp:Led a 5-week cross-functional rebuild of affirm.com (~1M monthly viewers) with Design, Marketing, and Engineering for web/mobile design continuity. Shipped onboarding and mobile conversion paths; generated an additional $500K GMV in a 3-day pre–Black Friday sale. Unlocked fast-follow A/B testing and CMS so marketing and eng could iterate without another full redesign cycle.
  • Org absorption:After an engineering manager left, absorbed affirm.com ownership and supporting eng surfaces with no replacement hire; kept Merchant Portal and affirm.com delivery on track with no operational regression.
  • Merchant Portal reliability:Raised availability 99.7% → 99.9% in one quarter and unblocked an Intuit launch covering hundreds of thousands of new merchants. Led weekly AI-tooling sessions where the team found and removed unused code paths that threw errant 5xxs and slowed incident diagnosis.
  • Tradeoff (domain decoupling):Mediated RFCs and system design across Staff+, Directors, and four merchant-engineering teams; chose to decouple service boundaries and drop an out-of-scope dashboard feature rather than force a database migration. Secured Director sign-off on merchant lifecycle architecture by Dec 2025 as groundwork toward a 99.99% availability target.

Developer Support Engineering Manager (L6 → L7), Partner Engineering|Affirm

San Diego, CA (Remote)|Jul 2021 – Mar 2025

  • Org design:Grew the developer-support engineering function from 1 to 9 engineers; owned interview rubrics and early-team hiring decisions. Shifted Tier-1/Tier-2 load to operations so engineers owned platform reliability.
  • Promotions:Ran weekly 1:1s and monthly career-growth reviews across a 9-engineer team; promoted a junior engineer to intermediate in ~1 year and then into product-building engineering, and supported a second engineer’s promotion cycle.
  • Partner APIs & payments:Owned technical operations and SLA reliability for strategic merchant accounts ($100M+ GMV) and Affirm’s flagship partner (Amazon, $10B+ GMV). Merchant checkout / confirmation-flow integrations via partner REST APIs and webhooks.
  • SLA recovery:Restored monthly attainment of an internal 99.9% availability target (also our partner commitments) through Mar 2025 after multiple missed months in 2024; shared metrics dashboards with Partner APIs and SRE to coordinate incident response across application code, infrastructure, and communications.
  • Collaboration (GMV signings):With Sales Engineers, Technical Writers, and plugin partners, produced availability projections that let account management sign $100M+ GMV merchants.
  • SLA telemetry:Architected automated SLA reporting and root-cause summaries (Python, Flask, Snowflake), eliminating 16 hours/month of toil and automating ~80% of SLA report generation and RCA drafting.
  • Observability:Built per-merchant dashboards and alerting that cut detection time for higher-volume merchant-scoped outages to under 5 minutes (previously 20 minutes–2 hours unnoticed).

Developer Support Engineer (L4 → L5), Partner Engineering|Affirm

San Francisco, CA (Hybrid)|Sep 2019 – Jul 2021

  • Merchant checkout integrations:Promoted L4→L5. Primary technical liaison for 300+ SMB merchants; diagnosed JavaScript, REST API, and webhook defects in checkout / payment-method integrations on Shopify, Magento, WooCommerce, and Salesforce Commerce Cloud.
  • DevX feedback loop:Built ETL pipelines towards Snowflake to cluster integration-defect patterns and convert developer feedback into platform fixes that reduced ticket inbound rate ~20% quarter over quarter.
