Building SEO-Driven WordPress & Shopify Systems at Absolute Digital
Working as a Senior Engineer at Absolute Digital gave me the opportunity to build and optimize high-performance SEO-focused digital platforms across WordPress and Shopify for multiple industries.

This experience strengthened my expertise in technical SEO, WordPress engineering, Shopify development, performance optimization, and scalable web architecture.
Building for search visibility starts with building correctly from the foundation.
Great to know that. Hope I can collaborate with you soon.
Let me tell you a crazy stat, business messaging usage jumped 53% in 2025. At the same time, the CRM market is already valued at over $126B, with 91% of companies actively using a CRM, and scheduling tools continue to grow at strong double digit rates as remote and hybrid work become the norm.
Now combine that with the rise of vibe coding. Today, almost anyone can build a SaaS product using AI, and around 84% of developers are already using AI coding tools in their workflow. However, while the barrier to building has dropped significantly, the gap in building something structured, scalable, and actually usable is still very real. Most apps that are generated quickly lack product thinking, system design, and integration depth.
That gap is exactly where templates start to make sense.
For @Anything x @Contra HQ remixathon, I built something that almost every vibe coder ends up trying to build at some point in their journey.
DOTS - An integrated web application template that combines CRM, team chat, and calendar functionality into a single clean interface. Think of it as a unified workspace where teams can manage contacts and deals, communicate in real time, and schedule meetings without switching between multiple tools.
With DOTS, teams can manage pipelines, collaborate through chat, and handle scheduling workflows inside one system. Instead of stitching together multiple SaaS tools, everything works together by design, which is exactly what modern teams are looking for - by simply modifying the template and remixing it, you can create and ship your very own SaaS with a proven POC.
DOTS is my first template on the marketplace and I can not wait to see how it performs because instead of creating another isolated demo, I focused on building a strong, reusable base that can serve as a starting point for real products, client work, or experiments in SaaS development.
If you are exploring vibe coding, building SaaS products, or working with clients who need fast and reliable solutions, DOTS is designed to give you a serious head start. It is not just an app, it is a foundation you can build on.
