- Platform Architecture & Business Impact
- Cut feature time to market by about 25% and engineering effort by about 30% across four countries. The marketplace seller platform was a single application for every market, so each release was slow and each new country meant rework. I designed a multi-tenant reference architecture (domain-driven design, micro-frontends, microservices) and moved 30+ applications onto it. Page performance doubled (Lighthouse 40 80), and teams outside the marketplace adopted the framework too.
- Reduced a key operational workflow's resolution time by 80% (10 days 2) and automated about 70% of cases, saving about 700 staff hours a week. Seller dispute handling was manual and spread across several systems. I designed a reusable platform (rules engine, ML model, system adapters) and extended it to three more case types within a month. Patent filed.
- Built a data platform processing 7 TB daily, transforming catalog data into actionable recommendations that improved listings and conversion for sellers. Utilized a Lambda architecture (Spark Streaming, GCP Dataproc, Solr; enhancing quality for over a million product listings.
- Made content reusable across markets by building a localization platform used by 57 applications. It has translated more than 5M words that can be reused in new markets without paying for translation again. I led the vendor evaluation and the build-versus-buy decision.
- Designed high-throughput partner data service managing 8K requests per second at peak, enabling cross-border catalog-porting for 100+ sellers to list in new markets without re-creating catalogs.
- Defined the platform strategy for expanding to 100+ countries. A pilot showed that launching a country took about 3 weeks of elapsed time for only 12 days of actual engineering work, because it depended on coordinating 10 teams. I proposed a self-service model in which business teams launch countries through configuration, backed by a requirement-classification framework and automated country-launch testing.
- Led the architecture to unify cross-border fulfillment. Order-cancellation rates were above target, so I traced the failures to five systemic root causes and set seven architecture principles. I then drove 13 architecture decisions across four engineering domains, replacing duplicated per-market systems with one orchestration layer.
- Delivered a new international trade route in 6 weeks. It passed architecture review the first time, shortening approval by about 30%, and launched with zero critical production defects.
- Designed multi-currency payments so 40+ downstream services needed no change, by isolating currency conversion behind a shared library rather than changing the core pricing model.
- Applied AI (2025 present)
- Designed multi-agent AI assistants (ReAct, MCP, LangChain4j) that diagnose production issues across databases, data warehouses and code. They shorten investigation time and run with least-privilege access.
- Automated production-readiness reviews with GenAI, replacing manual answers to 40+ checklist questions with answers backed by cited evidence. Also introduced AI-assisted code review and led GenAI adoption across the engineering org.
- Reliability, Cost & Engineering Leadership
- Lowered cloud infrastructure cost by about 18% and cut idle capacity by 30% through right-sizing after peak season, without affecting reliability.
- Led peak-season readiness for 12 business-critical services, achieving 100% pass rate on stress and chaos tests; created service-maturity model adopted by several teams to maintain production readiness year-round.
- Grew engineering capability: trained 100+ engineers as the org scaled from 20 to 300, mentored 3 engineers to promotion, and hired about 10 senior engineers.
