William Oliveira — software engineer building offshore operational systems

Engineering a clearer offshore operational picture

I am a software engineer and certified offshore RPAS pilot focused on maritime operations, operational intelligence, and accountable automation.

My work turns fragmented operational data into systems that people can inspect, challenge, and act on. I care about the gap between a dashboard and a real operation: data provenance, explicit limits, auditable decisions, replaceable providers, and human authority where safety is involved.

Operational intelligence
Vessels, people, activities, risks, alerts, and environmental constraints in one traceable picture.
Maritime + RPAS context
Software shaped by offshore workflows, field constraints, and qualified operational practice.
Safe automation
Explicit rules and guardrails that support decisions without replacing accountable humans.

Open-source offshore work

An evidence-driven command centre for offshore operations.

Unifies fleet positions, operational lifecycles, weather-window verdicts, risks, and alerts. Every verdict exposes the evidence behind it; simulated AIS and demo data remain visibly labelled.

Structural inspection triage where the model classifies but never measures.

Turns drone and ROV imagery into typed, severity-ranked defects bound to the structural zone they were found in, compared across campaigns and closed into a report an engineer can sign. Measurement is deterministic work the model is not allowed to do.

How I build

  • The operation comes first. Technology exists to reduce ambiguity in real workflows.
  • Evidence over unexplained scores. A verdict should expose its inputs, rules, and limits.
  • Simulation stays visible. Demo, simulated, stale, and unavailable data are never presented as live truth.
  • Humans retain authority. Software supports qualified decisions; it does not silently make safety-critical ones.
  • Open and replaceable. Prefer open standards, local-first operation, and providers that can be changed.
  • Security at the boundary. Tenant isolation, permissions, audit trails, secrets, and destructive actions need explicit controls.
