Senior🎓
Top SchoolJacob Seppanen is a Senior Mobile Engineer based in Portland with seven years of experience building robust React Native apps and native Android components in Kotlin and Java. He has led security-sensitive migrations and features—moving enterprise authentication in-house, implementing multi-factor and nonce-based protections with native modules for sub-200ms performance, and managing CI/CD and CodePush for safe, automated releases. At Sweater he integrated financial rails (Plaid, ACH, wire) and compliance flows, while also wiring third‑party webinar platforms into GraphQL-driven mobile experiences. Practical and detail-oriented, he pairs a machinist’s precision (AAS in Machine Tool Technology) with modern mobile architecture skills and a knack for creative DIY projects—like wiring a local phone network—bringing both engineering rigor and hands-on problem solving to product teams.
