• Crafted a next-generation frontend with Next.js, TypeScript, Tailwind & Storybook as part of a Scrum team, deployed with Vercel. This greenfield SaaS empowered the company to package risk & intelligence services in a unique way to a plethora of new customers.
• Created a "Service Status" page as part of a team, interpreting uptime statistics from AWS CloudWatch, deployed as an AWS Lambda, written in Go 1.20 with a frontend written in React, TypeScript & Tailwind. This tool enabled customer to always know the status of the service, reducing support tickets and customer confusion.
• Led a team as project manager to build a "Spotify Wrapped"-alike using React, Vite, TypeScript, CSS & deployed with Netlify. Using internal APIs, we annually summarised the efforts of our intelligence analysts with a humorous presentation, improving team morale & encouraging competition.
• Contributed to building an AI virtual assistant platform leveraging Go 1.20 & AWS Bedrock, integrating Claude 3.5 to deliver context-rich customer interactions.
• Created a fully-documented REST API using PHP 8 (Slim), PostgreSQL & deployed via AWS to enable customers to share user generated content with their colleagues within the company's applications.
• Helped create an AWS Lambda written in Go 1.20, which continuously processes & sends notifications from AWS SQS payloads, offering enhanced user customisation of notifications and savings on third-party service costs.
• Built multi-factor authentication and authentication logging with PHP 8 (Slim) into the internal "Authentication" REST API, improving application security & enabling the acquisition of customers with enhanced security needs.
• Implemented the third-party "Dragonfly" API to display their data alongside internally published intelligence using PHP 8 (Lumen) to provide customers with more sources.
• Built a "Developer" website in Jekyll (Markdown, Liquid, SASS, JS) to document the company's APIs, resulting in increased sales from API-only customers.
• Delved into CQRS to update a legacy, event-driven, PHP API (Lumen), allowing intelligence analysts to keep information and statistics up-to-date via the event stream.
• Enhanced incident email notifications by dynamically generating map images using PHP 8 (Slim), MapTiler API, MJML & CSS, improving client awareness of threats or dangers occurring in their locations of interest.

• Created a WordPress theme using PHP, SASS & JS (ES6, jQuery) as a central part of the company's global rebrand. By writing bespoke features, I reduced the reliance on third-party WordPress plugins from 63 down to 4. This vastly improved page load time and reduced employee frustration by making the website simpler to manage.
• Built a WordPress plugin using PHP 7.4, JS (jQuery) & CSS to create an asynchronous learning platform, empowering thousands of delegates globally to access workshop materials on-demand in multiple languages. My work replaced an expensive, third-party solution, prone to frequent outages.
• Converted a WordPress "multisite" into several, smaller databases with MySQL, giving all global branches the flexibility to manage, localise & translate their own websites to meet their regional marketing and sales goals.

• Developed hundreds of sales promotion websites for clients including Google, Dell & HP using PHP 7.4 (Laravel, Symfony, Blade), Vue.js, SASS (Bootstrap) & MySQL, deployed via DigitalOcean with Docker & Jenkins. These campaigns rewarded customers with cashback and gifts, incentivising tens of thousands of purchases, helping Opia's clients to meet their sales targets and strengthen brand loyalty.
• Led email campaign development, creating responsive HTML emails (MJML, Foundation for Email), tested with Litmus and delivered via Mailgun on behalf of clients including Samsung, Microsoft & LG. My work increased trust by reinforcing brand identity across digital communications and garnered positive client & customer feedback.
• Created a serial number validation system with PHP regex pattern matching to pre-validate customer claims. This reduced the amount of exploratory work required by the customer service team, minimising customer frustration.
• Represented the company at industry events by delivering presentations promoting best practices in responsive HTML email development. This helped establish Opia as a forward-thinking, tech-first employer and increased the number of job applications received from developers.
