Avery Hayes is a Senior Software Engineer in Boston with 11 years of experience building scalable backend systems, data pipelines, and product-focused APIs across companies from Google to Mailchimp, Axios, and Sendwave. They specialize in architecting maintainable systems and migrations—designing B2B API and DB layouts, leading cross-team code migrations, and creating guided onboarding frameworks that improve user flows and measurability. Avery has a strong track record of untangling complex business requirements into auditable data pipelines and running intricate backfills and third‑party integrations for growth initiatives. Equally comfortable stabilizing legacy apps and launching cloud-native projects, they blend pragmatic engineering with documentation and mentoring to raise team craftsmanship.
