Summary
👤
Senior🎓
Top SchoolSean Azlin is a hands-on engineering leader and technical advisor with 12 years of focused experience and a 20-year engineering pedigree in building scalable, revenue-generating products. Based in Bellevue, he’s driven large-scale migrations, platform initiatives, and AI-native product launches at OfferUp—bootstrapping new businesses like Autos and Shipping and delivering over $110M in revenue contributions across efforts. He blends deep backend expertise (microservices, DynamoDB, ElastiCache, SageMaker) with AI and GenAI orchestration—shipping MoE content-moderation and AI-powered marketplace posting systems using Claude Sonnet, GPT-4o, and custom embedding models. Sean is equally skilled in operational excellence and culture: he led org-wide cost savings of over $2M, standardized code quality across 500+ codebases, and founded a long-running engineering seminar series. Now advising pre-seed teams, he focuses on SEO-led growth, pragmatic MVP scoping, and hiring early engineering teams to scale reliably. A detail many miss: he combines startup scrappiness (14th OfferUp employee) with enterprise-grade process improvements that prevent incidents while accelerating innovation.
