About this service

Summary

Need a complex, custom-built web application or a site with unique functionalities?

I specialize in engineering high-performance, scalable platforms that go far beyond standard templates. I take sophisticated business requirements and transform them into robust, beautifully coded digital solutions.

This gig is for ambitious projects requiring custom logic, complex integrations, and advanced UX/UI execution.

What I Build (Complex Focus):

I handle the challenging requirements that matter:

Custom Application Logic: Developing bespoke features, client portals, and specialized internal tools.

API Integrations: Connecting systems like CRMs (e.g., HubSpot, Salesforce), payment gateways, or proprietary APIs.

Advanced UX/Interaction: Implementing high-fidelity design, complex filters, and unique data visualizations.

Scalability & Speed: Ensuring the architecture can handle high traffic and future growth seamlessly.

My 3-Phase Process:

A structured approach guarantees quality and alignment:

Strategy & Architecture: Technical discovery, database design, and interactive wireframing of complex user flows.

Full-Stack Development & Testing: High-quality code implementation (Frontend & Backend) with dedicated Unit and Integration Testing on all custom features.

Launch & Handover: Performance optimisation, secure deployment, comprehensive documentation, and post-launch support.

Key Technologies:

Frontend: React, Next.js, TypeScript.

Backend/CMS: Node.js, Python/Django, Headless CMS.

Design Conversion: Pixel-perfect development from Figma/Sketch.

Ready to Build? Please share your project vision, required integrations, and any existing design files.

What's included

Strategy & Wireframing
Discovery Session: A kick-off call to define goals, audience, and technical needs (CMS, integrations). Sitemap: A clear diagram showing all main pages and their hierarchy. Low-Fidelity Wireframes: Simple, grayscale layouts of the Homepage and 1-2 key internal pages (e.g., Services, Contact) focusing purely on content placement and functionality. Content Strategy Outline: Guidance on the type of text/imagery needed for each section.
Visual Design & Prototyping (The Look and Feel)
High-Fidelity Mockups: Full-color, branded design mockups of the Homepage and 2-3 key internal pages (using Figma/Sketch/Adobe XD). Design System / Style Guide: Defining typography, color palette (with HEX codes), iconography, and component styles (buttons, forms). Mobile/Tablet View: Mockups demonstrating the responsive design for key pages. Clickable Prototype: A link to a prototype (e.g., in Figma) that shows the client how the pages will link together.
Final Files & Developer Hand-off
Source Files: All original, multi-layer design files (e.g., Figma file) organized and named for easy use. Optimized Assets: Exported images and icons (in PNG/SVG format) ready for web use. Developer Specifications: Notes/annotations within the design files for margin, padding, and specific interactions (e.g., hover states). Post-Project Review: A 30-minute call to walk through the files and answer any technical questions from the development team (if applicable).
