Opulion Systems

We are a founder-led production systems engineering firm.

We design, build, harden, and operate software and AI systems where failure carries real operational, financial, or safety consequences.

We don't build software.

We build systems that have to survive reality.

Most engineering firms specialize in one layer of the stack.

We deliberately don't.

Our work spans the entire system:

• AI models & agentic systems
• Data pipelines & distributed backend services
• Cloud infrastructure & platform engineering
• Industrial protocols (OPC-UA, Modbus, Redfish, IPMI, SNMP)
• Edge computing & telemetry platforms
• Embedded software, firmware & drivers
• Hardware interfaces down to the silicon

That range isn't a marketing claim.

It's a necessity.

Production failures rarely happen where they first appear.

A model degrades because the data pipeline drifted.

A backend slows because an infrastructure assumption broke.

A robotics platform misses deadlines because of firmware timing.

A payment platform starts dropping transactions because the bottleneck lives several layers below the application.

Most vendors stop where their expertise ends.

We keep following the system until we find the actual constraint.

How clients engage us:

Clients typically bring us in at one of five stages.

Diagnose
Find why a production system fails when staging said everything was fine.

Architect
Design systems that survive real-world complexity, scale, and operational constraints.

Build
Deliver production-grade platforms from concept through deployment.

Harden
Eliminate reliability, scalability, and operational risks before they become outages.

Operate
Monitor, optimize, and continuously improve mission-critical systems.

Selected outcomes

• Recovered a failing AI system from 44% to 95% accuracy in five days.

• Reduced false positives by 41% across an 87-unit autonomous fleet.

• Delivered 96.8% OCR accuracy across 50,000 production documents every month.

• Shipped on-device voice inference at 22ms latency with 95.7% accuracy on NVIDIA Jetson Orin.

• Reduced LLM operating costs by 38% while increasing domain accuracy by 45%.

Founder-led engineering

Most consultancies win projects with senior architects...

...then hand delivery to junior developers.

We do the opposite.

Every engagement is personally led by Mostafa Dhouib, founder and principal engineer.

With 11+ years of experience and 40+ production systems shipped, he remains directly involved from architecture through production delivery.

We intentionally work with only a small number of clients each quarter.

That isn't a capacity constraint.

It's how we ensure the engineer accountable for the outcome is the same engineer designing, building, and standing behind the system.

Where we work

We don't specialize in industries.

We specialize in systems where the stakes are high.

Our clients span:

• Industrial Automation
• Defense & Unmanned Systems
• Robotics & Autonomy
• Healthcare & Medical Devices
• Critical Infrastructure
• Enterprise SaaS
• FinTech & Risk Platforms
• AI-native Products
• Cloud & Server Infrastructure

The industry changes.

The engineering principles don't.

If we're not the right engineering partner for your problem, we'll tell you before either of us wastes time.
