Real problems turned into web products.

Four projects that show end-to-end ownership, product decisions, and technical execution across different contexts.

International education portal

UniChristian

An international, multilingual digital presence built to strengthen authority and support student acquisition.

Next.js / React / TypeScript / Tailwind CSS

Other projects

Websites, landing pages, portals, and systems that expand the portfolio without competing with the core case studies.

Three areas, one standard of ownership.

I work directly with people who need to launch an idea, organize an operation, or improve an existing digital experience.

Websites & Landing Pages

Fast, responsive web experiences built around a clear goal, from institutional websites to landing pages designed for acquisition and conversion.

Need a site like this for your business?

I run a fixed-scope offer for small businesses that need their own website, with price and deadline agreed upfront.

EJA Nexus: Landing page & acquisition

Web Systems & Platforms

Internal systems, dashboards, portals, and web products designed around real business processes and operational needs.

CRM Mytrus: Internal system & operations

Automations & Integrations

Integrations and automations that connect tools, reduce manual work, and make digital operations more efficient.

Engineering that starts with the problem, not the technology.

Before choosing a stack or building an interface, I focus on what actually needs to work: the user, the process, the business goal, and what success looks like. Technology is the tool used to turn that into a fast, reliable, and maintainable product.

Technology chosen around the delivery context.

Tools that appear frequently in my current work, once the product, user, and goal are clear.

Frontend

  • Next.js
  • React
  • TypeScript
  • JavaScript
  • Tailwind CSS

Backend & data

  • Node.js
  • Supabase
  • PostgreSQL
  • REST APIs

Integrations & quality

  • Google Apps Script
  • GA4
  • GTM

I use AI as part of the engineering workflow (prototyping, debugging, documentation, and implementation) while keeping requirements, architecture, and validation under human ownership.

Technology and business on the same side of the table.

My background brings development, product, and experience together to turn real needs into well-executed web solutions.
