Luxury Jewelry E-Commerce Website – Gemsparx
Front-End & Full-Stack Developer (React & Node.js)
Gemsparx is a luxury jewelry marketing and e-commerce website designed to showcase diamonds, fine jewelry, and custom design services with a high-end user experience.
I developed this project using React for a fast, responsive front end and Node.js for backend functionality. The focus was on creating a visually elegant, conversion-friendly interface while maintaining performance, scalability, and clean code architecture.
The website features structured product categories, promotional sections, custom design workflows, and a modern UI optimized for both desktop and mobile users. This project demonstrates my ability to build premium marketing websites that align with luxury brand aesthetics and business goals.

http://mspterms.com/
I developed a scalable SaaS web application for MSPTerms, a document management and business strategy platform designed for managed service providers (MSPs).
The project involved building a fast, secure, and intuitive user interface using Nuxt.js, including authentication flows, dashboard layouts, and responsive landing pages. I focused on performance optimization, clean UI/UX, and seamless user experience across devices.
The result is a modern, production-ready SaaS platform that enables MSPs to manage documents, streamline operations, and support business growth with a professional, easy-to-use system.

I help teams and founders ship reliable, scalable full-stack applications from early MVPs to production systems used at scale.
As a Senior Full-Stack Developer, I focus on:
Building clean, maintainable frontends with strong UX foundations
Designing resilient backends, APIs, and data models
Making pragmatic tech decisions that hold up over time
Shipping fast without cutting corners
What I typically work on:
SaaS platforms & internal tools
Complex dashboards and data-driven apps
API-first systems and integrations
Performance, refactors, and technical debt cleanup I’m opinionated about code quality, architecture, and ownership but flexible about tools and stacks when the problem calls for it. If you need someone who can own features end-to-end, communicate clearly, and think beyond just “making it work,” let’s talk.

Building AI Agents That Actually Work: From Automation to Autonomy
I’ve been deep in the weeds building AI-powered automations and autonomous agents that go beyond simple prompts.
My current focus:
Designing task-oriented AI agents that can reason, plan, and take action
Automating real workflows (ops, research, content, internal tools) with LLMs + APIs
Turning messy, manual processes into reliable, scalable systems
Exploring multi-agent setups, tool calling, memory, and guardrails
The goal isn’t “AI for demos” — it’s production-ready AI systems that save time and unlock leverage.
If you’re thinking about:
AI agents for your product or internal team
Replacing repetitive workflows with automation
Shipping AI features that users actually trust
Happy to share learnings, patterns, and pitfalls I’m seeing as this space moves fast 🚀
