A regulated product
A payroll or VAT error is not just a bug: it ends up in a return filed with the MRA. Konta computes payroll under Mauritian law and rates (PAYE, CSG, NSF, PRGF), handles Workers’ Rights Act leave, keeps the books and prepares 15% VAT.
- Invoicing, quotes, expenses, purchasing and stock in one tool.
- Multi-company, with a dedicated workspace for accounting firms.
- Employee portal for payslips and leave requests.
Architecture decisions in writing
Every structural choice is recorded in a decision record: the problem, the options weighed, the choice and what it costs. A product maintained by one person has to be able to explain its own decisions.
- Symfony and API Platform API, React interface installable on phones.
- Background processing on Valkey rather than a dedicated message broker.
- Idempotent accounting writes: a replayed request never creates a duplicate.
- Perpetual inventory at weighted average cost, reconciled with the accounts.
AI where it saves time
A photographed receipt is read automatically: the suggested details are attached to the expense and confirmed by the user before reaching the books. AI prepares the entry; it does not decide for the business.
Operations designed for one person
- Kubernetes with infrastructure described in Terraform, and a staging environment on the same cluster.
- Automated, verified deployments and written incident procedures.
- Automated tests across the API, the interface and complete user journeys, on desktop and mobile.
Launching a product in a regulated field? I can design the architecture, build it and run it in production.
