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).
