Heirapi is a small team of integration engineers, protocol specialists, and support analysts based in Australia. We have spent years inside corporate IT estates, mapping mainframe data flows and building the API bridges that let old and new systems exchange information without friction.
We work alongside the people who keep critical infrastructure alive. These are the partners who rely on our API bridges to connect their mainframe estates to modern operations.
Integration partner for rolling inventory telemetry and legacy signalling interfaces.
Collaboration on secure patient record retrieval across regional hospital systems.
Joint delivery of a real-time production monitoring bridge from plant floor controllers.
Partner for asset management APIs linking field sensors to core billing mainframes.
Trusted advisor for cargo manifest integration between legacy terminals and port community systems.
Heirapi was founded by engineers who spent years on the wrong side of legacy integration projects — the side where a six-month timeline quietly becomes eighteen. We build custom API layers that connect modern corporate networks to mainframe architectures, and we do it with a small, senior team that stays on the job from discovery to production.
Our architects have worked with CICS, IMS, and VSAM transaction systems since before REST was a default answer. They know how to map a COBOL copybook to a JSON schema without losing the semantics that matter to the mainframe.
We treat each connection as a perimeter. Mutual TLS, credential vaulting for mainframe sessions, field-level encryption, and audit logging are designed into the bridge from the first diagram, not bolted on after a pen test.
Each engagement has a single delivery lead who talks to your operations team weekly. No handoffs between account managers, no surprise change requests. If a mainframe constraint shifts the schedule, you hear it from the person who can fix it.
The team that builds your bridge also staffs the support desk. When a batch job fails at 2 a.m., the engineer who answers knows the transaction flow, the error codes, and which mainframe region to check first.
