Sultan Kautsar

Where engineering meets marketing.

I build and maintain digital products, websites, marketing systems, and technical infrastructure for businesses and independent projects.

Case studies

2026

Case studies are anonymized: no client names, accounts, or figures from client data.

Focus

My work usually sits between engineering and marketing, covering development, analytics, tracking, automation, infrastructure, and the systems that connect them together.

I've worked on more than 75 websites across development, maintenance, migration, technical SEO, infrastructure, landing pages, and ongoing production support.

I also work extensively with marketing technology, including analytics implementation, Google Tag Manager, conversion tracking, consent management, and measurement architecture for agencies and businesses in international markets.

My approach is technology-agnostic. I choose the tools and architecture based on the requirements, constraints, and outcome of each project.
