02Client Work

Two systems clients paid for. I closed both deals and wrote code for both.

How an engagement runs

  1. 01ReachI find the client myself.
  2. 02ScopeWhat they ask for is rarely the problem.
  3. 03FlowWe draw the pipeline together, before any code.
  4. 04ClosePrice and timeline, signed.
  5. 05BuildI stay in the codebase.
  6. 06Hand overDocs and training until they run it alone.

Clients taught me the rest. At Hotel Genio Syariah I removed 87 percent of the manual work, trained 18 staff to run it, and left nothing broken behind me.

Esports

Played Mobile Legends competitively (Ex-Pro Player). It teaches you to decide fast and precisely without the full picture.

Consulting

Trained as Arthur D. Little's mentee. I learned to structure a problem before touching the solution.

Community & Growth

Co-founded the first blockchain club at UNS, so people could ask basic questions without feeling stupid.
