Conceptual view: records are saved on the device first, then synchronized when a connection returns.

The problem

Oil and gas operators are required under the Clean Air Act to run leak detection and repair (LDAR) programs: survey equipment for methane leaks, record what they find, and complete repairs on fixed deadlines. Most of that work happens at remote production sites where there is little or no cellular coverage.

When I joined Iconic Air, the existing mobile app could not support that kind of field work. If a tool loses records or stalls when the signal drops, crews stop trusting it, and the operator ends up with gaps in its compliance record.

What I built

I took full responsibility for the mobile software, set the old app aside, and designed a new platform for iOS and Android. It reached customer field teams through beta builds within four and a half months.

  • Leak detection and repair: surveys, leaks, repairs and resurveys tied to individual pieces of equipment.
  • Emissions event tracking.
  • Compliance rules that differ by state.
  • Historical surveys, leaks and repairs migrated from the previous system.

How it works offline

Every record is written to the device first. A technician can complete a full day of surveys without a connection, and nothing depends on the network being there at the moment of capture.

When connectivity returns, the app synchronizes queued records with the central platform, where they feed compliance tracking and reporting. The hard parts are the ones users never see: keeping linked records intact through a crash or a dead battery, and merging work from several technicians who were offline at the same time.

The interface is built for the conditions: fast, simple, and usable outdoors in bright sun by people wearing gloves.

Outcome

Crash rates fell by 35% and synchronization became 15 times faster, which made the app dependable enough for daily field use. It is now used by 14 operators across about 22 states, including Fortune 500 and publicly traded energy companies. The wider Iconic Air platform serves 22 operators in more than 30 states.

Asuene USA acquired Iconic Air in October 2025. I continue to own the mobile architecture as Principal Software Engineer.
