Expertise
Things I do
exceptionally well.
I work across the full product lifecycle, from the napkin sketch to the production deploy. Here is where I add the most value.
01
Product Strategy
Defining what to build, for whom, and why it matters. Market positioning, feature prioritization, and go-to-market planning grounded in real user data.
02
Design Systems
Building cohesive, scalable component libraries that keep interfaces consistent as products grow. Tokens, variants, documentation, governance.
03
Frontend Architecture
React, Next.js, and TypeScript at scale. Performance-obsessed builds with Core Web Vitals in green from day one. Server components, edge rendering, the works.
04
Rapid Prototyping
From concept to clickable prototype in days, not months. High-fidelity builds for investor demos, user testing, and internal alignment.
05
Technical Advisory
Fractional CTO engagements, architecture reviews, and technical due diligence for pre-seed through Series B startups. Honest assessments, no fluff.

How I Work
A clear path from
idea to impact.
01
Understand
Deep-dive into your business, users, and market. I interview stakeholders, audit existing systems, and map the competitive landscape. No assumptions, only evidence.
02
Define
Synthesize research into a product brief with clear scope, success metrics, and a phased roadmap. We align on what "done" looks like before a single pixel moves.
03
Build
Rapid iteration in two-week cycles. Design and code move together. You see working software every Friday, not slide decks. I write the code myself and own the output.
04
Launch & Learn
Ship to real users, instrument everything, and iterate based on actual behavior. I stay engaged post-launch to optimize, not just hand off and disappear.
Kind Words
What clients
say about me.
Tap a card to cycle through testimonials from founders and leaders I have worked with.
"Kai took a vague idea and turned it into a product that generated $400k ARR within eight months. He thinks like a founder, not a contractor."

Elena Moretti
CEO, Meridian Analytics
"We hired Kai for six weeks. He rebuilt our entire frontend, cut load times by 73%, and left us with a codebase we could actually maintain."

Tobias Kramer
CTO, Canopy Health
"The rare person who can whiteboard product strategy at 10 AM and push production code at 4 PM. Worth every dollar and then some."
