Software engineering

We build the systems your business runs on

Custom software, process automation and systems integration for companies in Bulgaria and across Europe — engineered by a senior team you talk to directly.

02 — Background

Industries we understand from the inside

Before WZCO, our engineers spent years building production systems in demanding data-heavy industries. That experience is in the company's DNA.

Commodity markets & price reporting

Years spent building price-reporting infrastructure: ingesting market data, enforcing methodology, publishing numbers traders act on.

Maritime intelligence & AIS tracking

Vessel-tracking systems processing live AIS streams — position data at scale, port-call detection, fleet analytics.

Procurement & tendering platforms

Tendering workflows end to end: structured bids, deadlines, evaluation, and the audit trail that regulated procurement demands.

Geospatial & environmental data

Mapping and environmental monitoring systems: satellite and sensor data, spatial databases, map-driven interfaces.

03 — Process

How we work

Four steps, each with a concrete deliverable in your hands. No black boxes between kickoff and launch.

  1. 01

    Discover

    We map your process, users and constraints in working sessions with your team. You get a written scope, an honest estimate and a recommendation — even if the recommendation is not to build.

  2. 02

    Design

    You get the system architecture, the data model and the key screens on paper before code is written. Changing a diagram costs an hour; changing a deployed system costs a month.

  3. 03

    Build

    Working software lands in reviewable increments every week or two, on a staging environment you can open. You see progress with your own eyes, and course corrections stay cheap.

  4. 04

    Support

    After launch we monitor the system, fix what surfaces and extend it as your business changes. You get an agreed response window and a direct line to the engineers who built it.

04 — Why WZCO

What you get with us

Senior engineers only

The company is built on 10+ years of hands-on production software experience. Nobody learns on your budget.

A direct line to the builders

You talk to the engineers doing the work — no account managers, no relay stations, no translation loss.

EU-based, GDPR-conscious

We work from Bulgaria in EET/CET hours, convenient for European clients, and treat data protection as a default, not an add-on.

Answers within one business day

Every inquiry gets a substantive reply within one business day. During a project, you always know where things stand.
