Senior Software Engineer

Kai Jenkins

Building generative AI products and full-stack platforms, from infrastructure to interface.

I build AI-powered products, developer platforms, and accessible customer experiences. I’m a big-picture thinker who enjoys questioning assumptions and turning complex problems into achievable milestones. At Delta Air Lines, I lead work from retrieval and evaluation pipelines to reusable component infrastructure

Selected work

Engineering at the level of systems and outcomes.

A selection of enterprise work, shared through the responsibilities and outcomes I can discuss publicly.

Delta Air Lines2024 – Present

Technical Lead and Senior Software Engineer

Mach 1 AI Design Assistant

An internal generative AI product that applies the Mach 1 Design System to transform screenshots, wireframes, and legacy interfaces into compliant prototypes.

Outcome

Accelerated design-system adoption by reducing concept-to-UAT delivery from 3–6 months to approximately 24 hours.

What I owned

  • Turned design-system knowledge into a practical product capability for engineering and design teams.
  • Established quality and evaluation practices for reliable, standards-aligned output.
  • Created the production observability needed to operate and improve the platform responsibly.
  • Led a cross-functional team of five engineers across architecture, roadmap planning, review, and delivery.

Outcome

Drove adoption across more than 15 engineering teams and contributed to an estimated $19 million in engineering cost avoidance.

  • Built production-ready component foundations and utility tokens with TypeScript and Tailwind CSS.
  • Made design-system and accessibility guidance practical for teams shipping customer-facing products.

Software Engineer

SkyMiles Cloud Modernization

A modernization effort that moved high-traffic SkyMiles workflows from legacy infrastructure to a cloud-native foundation.

Outcome

Reduced average page-load times from approximately eight seconds to four-to-five seconds while improving resilience.

  • Modernized legacy customer workflows while preserving continuity across dependent systems.
  • Improved runtime performance and reliability for frequently used SkyMiles experiences.

How I work

Start with the whole picture. Make the path achievable.

I start with customer needs and scale, then plan with detail and taste. I care about making complexity understandable and giving a team a path it can confidently deliver

Beyond the work

Away from work, I’m usually following soccer, going down an aviation rabbit hole, or catching up on the latest in AI and technology. And yes, blue is my favorite color

  1. Question the premise

    I like challenges that make me think. I use logic and first principles to test assumptions before a team commits time and complexity to them.

  2. Design the path, not just the answer

    I break ambitious problems into achievable milestones, with enough detail to expose risk while keeping the larger outcome in view.

  3. Collaborate, systematize, accelerate

    I thrive in collaborative teams and look for the systems, automation, and everyday uses of AI that accelerate repeatable work without outsourcing judgment.

Career progression

From customer systems to enterprise technical leadership.

A progression from modernizing customer journeys to leading applied AI and shared platform initiatives.
