Software engineering & AI search.

Building a product or improving an existing site? I bring hands-on engineering to web, mobile, AI, and search optimization.

I work with teams in Surabaya, Jakarta, and across Indonesia.

SEO & AI search visibility

I help search engines and AI systems find and understand your business through technical SEO, GEO, and AEO.

  • Crawl, rendering, metadata, and structured data audits
  • Content that answers questions, with evidence and author profiles
  • Topic planning and search visibility measurement

How we work together

  1. Talk it through

    Tell me about your users, workflow, and constraints.

  2. Set priorities

  3. Build and evaluate

    We review working increments, then I prepare documentation and handover.

Before we start

What is the difference between GEO, AEO, and SEO?
SEO helps people find your pages in search. AEO (Answer Engine Optimization) organizes clear answers. GEO (Generative Engine Optimization) helps AI systems understand and reference your information. All three rely on useful content, crawl access, and evidence.
Do you work with teams in Surabaya and Jakarta?
Yes, I work with teams in Surabaya, Jakarta, and across Indonesia. We agree on collaboration and any meeting requirements before starting.
Do GEO and AEO guarantee inclusion in ChatGPT or Google AI answers?
No. Each platform chooses its own sources. I improve technical access, content clarity, and evidence, then measure visibility across relevant questions.
What does a GEO and AEO audit deliver?
You get findings on crawl access, rendering, content, metadata, and structured data, with prioritized fixes and a measurement plan. I can also handle implementation.
What projects are a good fit for working with me?
Web, mobile, and AI products that need both architecture and hands-on engineering. I built APPA Academy for 500+ academies, an AI research platform at Quantamental AG, and software for Indonesia’s Ministry of Public Works. My portfolio can help you assess the fit.
How do we start and determine cost?
Send your goals, product or website link, constraints, and timeline. We agree on scope, deliverables, schedule, and cost before starting.
