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

Our engineers have spent years building production systems inside these domains. We arrive knowing the vocabulary, the edge cases and what usually goes wrong.

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.

Manufacturing & recycling operations

Plant floors where material changes state at every step: stock that has to agree with the movements behind it, weights, waste and output reconciled at month end.

IT service & vendor operations

Support operations at scale: queues that never empty, cases split into tasks, shift rosters, and a change history somebody will eventually have to defend.

Geospatial & environmental data

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

Retail, e-commerce & FMCG

Online shops kept in step with the warehouse, the ERP and the payment provider — and the promotions that take all their traffic in a few weeks, with receipt validation and duplicate detection behind them.

Architecture & design studios

Practices whose work is visual first: project archives that stay navigable as they grow, images that still load on a phone, and a site the studio updates without calling anyone.

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.

05 — Selected work

Work we are proud of

A selection of systems our engineers have built and run in production. Full portfolio on its own page.

The materials ERP preview: a purchased-materials ledger listing dated deliveries with supplier, material, price and quantity

Materials ERP for a plastics recycler

The system a recycling plant runs on: bales come in, are sorted, washed, ground and granulated, and leave as sellable material — every movement weighed, booked and reconciled.
