I will improve your website design and user experience
Oliver Martinez
About this gig
Does your website work, but the interface feels outdated, inconsistent, awkward, overly generic, or a little too much like AI slop?
I'll improve the UI and user experience directly in your existing website or web app. I can work on components, sections, forms, navigation, dashboards, or larger parts of the interface, improving visual hierarchy, spacing, typography, consistency, usability, responsiveness, and overall polish.
This is an implementation service, not just a design mockup. I work directly with your existing frontend code, including HTML/CSS, JavaScript, TypeScript, React, Tailwind CSS, Astro, Next.js and similar stacks.
Package scope is based mainly on the amount and complexity of the interface work, not strictly on page count.
This Gig focuses on UI/UX and frontend improvements. Backend systems, payment or shipping logic, API integrations, and plugin installation are not included unless agreed separately.
For unusual or complex projects, message me first and I can create a custom offer.

Hi! Oli here ☝🏻👹
I’m a web app developer who likes building things that feel fast, polished, and pleasant to use. I care about UI, performance, accessibility, solid architecture, and all the little details that make a product feel properly finished.
I work across the whole web app, from interfaces and existing codebases to backend logic, databases, integrations, deployment, and complete products. I’m always happy to dig into a weird problem and figure out how to make it better.
If you have something you want to build, improve, or finally ship, tell me about it 🤩

FAQ
Do you only provide a design mockup?
No. I work directly on your existing website or web app and implement the UI/UX improvements in the frontend code.
What do you need from me before starting?
Access to the existing project or codebase, a short explanation of what you want improved, and any references or examples you like.
What if my project does not fit one of the packages?
Message me first. If the scope is unusual or more complex, I can create a custom offer based on the actual work required.
