My Freelancing Experience

Most of my freelancing experience has revolved around Wix, WordPress, and Shopify websites. I have helped businesses rank second for local SEO. The work varies from client to client—either improving the UI/UX of their website, building a new site from scratch, improving speed, SEO, automating tasks, or setting up integrations between their tools and platforms.

I like to approach each contract—unless the work is explicitly defined—by applying the 80/20 rule. I start by auditing site performance, accessibility, and SEO structure, reviewing their website and third-party services, and identifying high-impact changes that require the least amount of time. From there, I handle technical fixes such as schema setup, core web vitals optimization, and responsive design adjustments to improve engagement and conversions. I’ve also implemented email automation, lead tracking, and API-based workflows to streamline client operations.

My Computer Science background and multi-node cluster build-out—hosting and running my own open-source infrastructure—help me evaluate and recommend cost-efficient solutions. This enables clients to automate manual work, reduce monthly service costs, and gain more control over their digital presence.
