Scalable Architecture

I design robust system architectures that survive rapid growth. From Micro-frontends to Monorepos, I ensure your codebase stays maintainable as your team grows from 1 to 100.

  • Modular Component Systems
  • Design System Engineering
  • Performance Benchmarking

Performance Optimization

Millisecond improvements equal millions in revenue. I audit and optimize Core Web Vitals, reducing TBT and LCP to ensure your users stay engaged and convert faster.

  • Code Splitting & Treeshaking
  • Asset Optimization Pipelines
  • Edge Caching Strategies

Product Mindset

I don't just write code; I build products. I work closely with design and marketing teams to ensure technical decisions align perfectly with business KPIs and user needs.

  • A/B Testing Integration
  • Analytics Architecture
  • Accessibility (a11y) Compliance

Obsessed with
Metrics.

I believe that if you can't measure it, you can't optimize it. Every project I touch undergoes rigorous lighthouse auditing and performance profiling.

MY PHILOSOPHY

Brutal Clarity
over Decoration.

I believe that the best interfaces are invisible. A user should never have to think about the technology they are using; they should only feel the ease of achieving their goal.

My approach to development is rooted in "Digital Brutalism" — stripping away the noise to find the most efficient path between data and the user's mind.

Frequently Asked.

Can you work in multiple timezones?

Yes. I have spent the last 5 years working with teams across NYC, London, and Tokyo. I maintain a flexible schedule with a minimum of 4 hours overlapping with your core team.

How do you stay up-to-date with tech?

I dedicate 10% of my weekly capacity to R&D. I actively contribute to RFCs in the Next.js ecosystem and attend key conferences like React Conf and Next.js Conf.
