Our Story

Delta’s defining differentiation is staying embedded long-term: 

  • U.S.-based delivery (fully domestic team)
  • Embedded collaboration: works alongside internal product and engineering teams
  • Long-term partnership: continuity across roadmap cycles, releases, and maintenance
  • Legacy-first comfort: deep experience improving older Rails systems without rewrite everything pressure
  • Fractional technical leadership: fractional CTO support for strategy, prioritization, and architecture decisions
