DevOps SLA Monitoring
◎ Capability spotlight

A transaction system your customers and agents can both trust.

The brief we keep solving: an institution needs to move value between end-users, agents, and external payment rails — reliably, auditably, across every channel its customers actually use.

We build the full stack: a core ledger with double-entry accounting and wallet balances, integrations with Mobile Money operators for top-ups and payouts, channel-specific front-ends (app, USSD, SMS, POS), and a backoffice where operations can investigate, reconcile, and act.

The same architecture that powers a national-scale distribution network — with customer wallets, agent wallets and POS-based retail — applies directly to digital banking, micro-insurance, agent banking, social transfers, and any system where accounts, transactions, and multi-channel access are the foundation.

DEV PM OPS INFRA QA ARCH core

Hepi Tech is a Swiss engineering firm based in Geneva, founded in 2023 by a senior systems engineer with fifteen years inside telecom and payment systems integration — the world where uptime is measured in nines and every message has to be accounted for.

We work senior-to-senior and remote-first: you deal directly with the engineer who designs and builds your system. No account managers, no hand-offs. For larger scopes, we bring in vetted specialists around the project.

Today we help run high-volume mobile money platforms in West Africa. Our engineering background spans telecom operators, banks, insurers and public institutions, and that is where we are headed next: organisations that need a partner who understands both the engineering and the business of money movement.
