The problem

Field-sales incentive schemes are full of rules and edge cases. KASEP turns raw sales performance data into correct, auditable incentive payouts for Telkomsel's sales force.

What I did

01A PostgreSQL-backed engine

Sales and incentive data modelled in Postgres, with the calculation logic running over it.

02Strict typing throughout

The codebase enforces strict TypeScript types to keep payout calculations correct.

03TODO

Describe the incentive rules, inputs, and reporting outputs.

The outcome

TODO: summarise impact for the sales team and next steps.

Have something like this?
