Are you looking for a modern, high-performance website that loads quickly, supports conversions, and strengthens your brand's online presence?

In modern web business, page load delays and confusing user flows directly hurt conversion rates, while outdated site structures can keep your brand buried beneath competitors in search engine results. When mobile experiences feel clunky or slow, prospective clients quickly move on to competing services.

I work with growing businesses, startups, and digital brands to build fast, reliable, and search-optimised web platforms designed to support long-term growth.

WHAT I DELIVER FOR YOUR DIGITAL PRESENCE:

1. Search Engine Optimisation & High-Speed Web Architecture:
I build websites using clean semantic markup, structured metadata, and performance-first coding practices. By targeting modern Core Web Vitals standards and integrating Google Analytics tracking, your platform gains the speed, measurable data, and technical foundation search engines prioritise.

2. AI Automation, Intelligent Chatbots & API Integrations:
To streamline business operations, I build practical AI solutions including customer support chatbots, automated text and data parsers, and intelligent workflow automations. These are built using robust LLM APIs including the OpenAI API (GPT-4o), Google Gemini API, and Anthropic Claude models, integrated via Python and FastAPI.

3. Secure Cloud Infrastructure & Database Deployment:
Drawing on certified cloud architecture knowledge, I configure Linux server environments, structured PostgreSQL databases, and containerized Docker deployments across platforms like Oracle Cloud to support high uptime, secure data handling, and reliable backend performance.

4. Responsive Web Applications & SaaS Client Portals:
Because mobile traffic represents a critical share of modern digital interactions, every project is built mobile-first. Beyond landing pages, I build custom web systems, SaaS dashboards, and client portals using Next.js on the frontend and high-concurrency Golang or Python microservices on the backend.

PORTFOLIO HIGHLIGHTS & MEASURED OUTCOMES:

The following platforms in my portfolio illustrate the range of technical approaches I apply:
• Tranvas: A comprehensive personal growth ecosystem and web platform unifying habit tracking and financial planning, achieving sub-50ms backend query response times across daily user workflows.
• HandleMyFile: A privacy-first, browser-native document workstation utilising WebAssembly to merge, split, compress, and OCR files directly in the client's browser without server uploads, eliminating 100% of cloud processing overhead.
• SolveMyMedia: A browser-based media processing tool for audio and video, enabling users to convert, compress, and optimise media files locally without uploading to a server, avoiding third-party compute fees.
• Visit Banjarmasin: A digital tourism and cultural exploration web portal built with a mobile-first layout and optimised for high-speed content delivery, achieving sub-200ms page load speeds on mobile networks.

VERIFIED TECHNICAL CREDENTIALS:

• CS50's Introduction to Artificial Intelligence with Python (Harvard CS50)
• Google Analytics Certification (Google)
• Oracle Cloud Infrastructure Certified Architect Associate (Oracle)
• Software Engineer Certificate (HackerRank)
