Software that works where bandwidth is scarce.

I build lightweight web and Android products. Start with a focused performance and usability review, or one small workflow worth shipping.

Work with me · Lightweight Product Review

Find where users get stuck.
Know what to fix next.

For founders and small teams with a slow or unfinished web or Android product. I review one agreed flow—first use, signup, loading or a key interaction—and turn the findings into a prioritised repair plan.

  1. 01 · Agree the scope

    One flow, target devices and network conditions, clear acceptance criteria. We confirm availability, access and payment terms before work starts.

  2. 02 · Get evidence, not guesses

    Reproducible issues with screenshots or recordings, measurements under stated conditions, and a ranked list of failures, friction and cosmetic improvements. Emulation is labelled; a real-device claim needs a real-device test.

  3. 03 · Choose the next step

    A walkthrough of the findings and a scoped repair estimate if implementation makes sense. You can take the plan to your team; implementation is separate.

US$300 for the scoped review. Scope, currency, applicable taxes, payment method and delivery window are agreed in writing before booking. No payment is taken on this page.

This is not a whole-product audit, security certification or promise of conversion uplift. Production changes and unlimited testing are not included.

Send the product link, the problem users face, target devices and budget range. Please do not send passwords or customer records.
