I contributed to development and optimization work related to the Healthie healthcare platform, a modern telehealth and electronic health record system used by thousands of health and wellness providers.
The project involved enhancing user-facing components and improving the performance of data-driven healthcare interfaces used by clinicians and patients. The platform provides tools for appointment scheduling, patient portals, telehealth sessions, and practice management.
My work focused on improving frontend components and integrating healthcare data services to ensure smooth interactions between providers and patients within the platform.
Healthie is designed to help healthcare organizations manage operations, patient engagement, and telehealth services through a unified digital system.

This project is a scalable multi-vendor marketplace built on Bagisto (Laravel + Vue.js). I implemented vendor-based architecture with separate seller dashboards, commission management, product approval workflows, role-based access control, and dynamic catalog management. The system supports multi-store, multi-currency, REST APIs, and modular package customization. I optimized database queries, extended core modules, integrated payment gateways, and ensured secure authentication and performance tuning for production deployment.

I contributed to the front-end development of the Bagisto eCommerce website, working within an existing production codebase. My focus was on refining layout structure, improving visual hierarchy, and ensuring consistent styling across shared components using HTML, CSS, and JavaScript.
The work included UI polish, responsive behavior across breakpoints, and targeted improvements to spacing, typography, and component reuse, while preserving performance and the platform’s overall architecture.

💚 Health.io (http://Health.io) — Health Monitoring Web App
Health.io (http://Health.io) was like a high-tech wellness playground, but users were getting lost in complex health data and slow responses.
The main challenge was making all the data—user metrics, AI insights, and recommendations—flow smoothly and be instantly accessible. I resolved all technical issues by integrating vector search for fast AI-driven insights, caching with Redis for speed, and secure backend data handling.
Result: the app turns complex health data into a fun, usable, and smart wellness companion—fast, reliable, and just charming enough to make users smile.

🌍 Pacific Global Health — Site Rebuild & UX
Pacific Global Health’s website was like a sprawling library with books scattered everywhere—users struggled to find programs, resources, and key information quickly. I jumped in as a full stack developer, using MongoDB, Express, React, and Node.js (MERN) to reorganise the site, improve search, and create intuitive navigation so visitors could find exactly what they needed without wandering in digital limbo.
Result: a smooth, responsive, and engaging experience that turns confused visitors into informed users while keeping everything fast, clear, and just a little bit charming.

🤖 Generative AI & ML Pipeline — AWS SageMaker
I wrestled with a bunch of generative AI models, trying to figure out which ones actually made sense and which ones were just making stuff up. To tackle that, I ran careful evaluations and measured every quirky output to ensure accuracy and efficiency. When models were being stubborn, I jumped in with some fine-tuning magic and hyperparameter tweaks to get them to behave like proper AI citizens.
Deploying them on SageMaker endpoints was like setting up a tiny AI café—real-time, ready for testing, and fully operational. Managing S3 datasets and artifacts kept me on my toes, ensuring everything was preprocessed and versioned
Result: the models were generating better outputs, the pipeline was humming smoothly, and I had proof that Python, AWS, and I make a pretty unbeatable team.

🛒 Xpromo — Commerce UX & Workflow Rebuild Xpromo’s website used to feel like a giant warehouse where everything was scattered—users couldn’t tell if items were local stock, factory-direct, or if they’d arrive before next Christmas. I jumped in as a full stack developer, wielding Next.js, React, and Tailwind CSS like a digital Swiss Army knife to reorganise the UX, add smart filters, and slap bold “Get your free quote” buttons so customers actually knew what was what.
Result: faster quotes, clearer UX, improved conversions and zero frustration-induced hair-pulling. Tech & impact: Next.js, React, Tailwind CSS, server-side rendering optimisations, real-time inventory visibility and instant mock-up generation.
