About me

I’m a Senior Full-Stack Developer with strong experience building reliable, scalable, and high-performance web applications from concept to production. including JavaScript, TypeScript, React, Python, FastAPI, REST APIs, PostgreSQL, SQL, Redis, Docker, cloud deployment, automated testing, and Git

I build and automate web systems that remove manual work for growing businesses from customer-facing sites to the back-office workflows that run behind them.

For the past 4+ years I've worked across the full stack: React, Next.js, and Node.js for custom web apps; PHP, WordPress, and Elementor for content-driven sites; and GoHighLevel, Creatio CRM, and
Power Automate for CRM and process automation. I'm currently an embedded developer supporting enterprise CRM operations (workflow automation, process QA, integration troubleshooting) alongside freelance web development work.

What I bring to a project:
✅ Full-stack builds — from a marketing site to a functional web app, built to actually load fast and convert
✅ CRM/automation setup — GoHighLevel funnels, pipeline automation, and process workflows that replace manual busywork
✅ WordPress/Elementor sites that clients can actually update themselves afterward, without breaking anything
✅ E-commerce & payments — WooCommerce stores and Stripe integrations built to just work, no surprises at checkout

If any of this sounds like what you need, feel free to reach out - happy to hop on a quick call first to see if it's a good fit before anything official.
