Industries

Purpose-built for the sectors we know deeply

Generic software development is not what we do. Each industry below represents domain expertise built from real project work.

Battery & solar monitoring platforms built for operations.

Real-time SOC/SOH dashboards, string-level inverter diagnostics, rule-based alarms and SCADA integration over Modbus TCP, IEC 61850, and SunSpec. React interfaces updated via WebSocket telemetry.

Engineering principles

How we think about building software

The sectors above differ in protocol and physics, but the engineering discipline behind them does not. These principles decide how we build, whether the data comes from an inverter, a charge point or a transcoding worker.

01

Domain before code

We study the industry, its protocols, its constraints, and its operators before we write a line. Requirements that come from domain knowledge produce software that fits.

02

Clarity under complexity

Complex systems should have clear interfaces. We design APIs, dashboards, and data models to reduce cognitive load, not add to it.

03

Transparency as default

Weekly demos, shared task boards, open code reviews. We work in the open so you always know where things stand.

04

Quality in delivery

TypeScript everywhere, tests before merges, automated CI. Quality is not a phase, it is the default mode of working.

05

Built for production

We design for uptime, observability, and safe deployment from the start. OpenTelemetry, structured logging, and rollback plans are not afterthoughts.

06

Long-term partnership

We track production metrics after launch, flag regressions proactively, and treat your product as a codebase we will be accountable for.

Process

How we work

Domain research before architecture. Architecture before code. Delivery with visibility at every step.

01

Domain immersion

We study the industry, its protocols and its operators. Requirements derived from domain knowledge produce software that fits.

02

Architecture proposal

We design the system before building it: data flows, integration points, service boundaries, and client-facing interfaces.

03

Implementation

Iterative delivery in short cycles. TypeScript, automated tests, code review, and weekly demos throughout.

04

Integration & QA

We integrate with your existing systems (SCADA, CRMs, cloud infrastructure) and run both automated and manual QA.

05

Launch & monitoring

OpenTelemetry-instrumented deployments with structured logging, alerting, and rollback plans ready on launch day.

06

Post-launch support

We track production metrics, triage regressions, and remain available via Slack or Telegram after delivery.
