SOFTWARE & ELECTRONICS, ONE TEAM

We build the device — and the software that runs it.

Custom software and embedded electronics for teams who need both sides: sensors and firmware on one end, the platforms that turn their data into decisions on the other.

WHAT WE DO

Two disciplines. One team.

Most studios pick one side of the wire. We do both, so nothing gets lost in the handoff between the device and the platform reading it.

Custom Software Development

  • Web apps & admin systems
  • Internal tools & dashboards
  • APIs & data platforms
  • Legacy system modernization
  • Mobile-friendly, installable (PWA)

Custom Electronics & Embedded Devices

  • Arduino & embedded firmware
  • Sensor & data-acquisition hardware
  • Field-deployed IoT devices
  • Device-to-cloud data pipelines
  • Prototyping through to production builds

HARDWARE + SOFTWARE FLAGSHIP PROJECT

Aerosol Posts — Radioecological Environmental Monitoring

Custom Arduino-based air-quality sampling devices deployed at monitoring posts around the Kozloduy Nuclear Power Plant measure air flow and radioactivity in real time. Readings feed a Laravel + React platform with live maps, historical charts, and role-based access — replacing a decade-old legacy system, data and all.

SOFTWARE LEGACY REWRITE

Task Scheduler — Work-Order & Scheduling System

A full-stack rewrite of a decade-old Laravel 5 monolith for a metrology and technical-monitoring team. Staff see dated tasks — maintenance checks, equipment calibration, inspections — on a shared, color-coded calendar; managers create, reassign and print work orders, and staff close their own with a recorded reason.

  • Data-driven roles & permissions, editable at runtime — not hardcoded
  • Cross-subdomain SPA authentication, solved end to end
  • Ten years of legacy data migrated, including a silent charset-corruption fix
  • Deployed and debugged on real Windows/IIS production hosting

SOFTWARE

PastryManager — Bakery Back Office & Storefront

An order-to-production-to-inventory system for a bakery business: recipe-driven production batches, live stock tracking with low-stock alerts, and a bilingual public storefront where customers browse the catalog and order online.

SOFTWARE LEGACY REWRITE

Transportation company — Reservation & Dispatch Platform

A central reservation system for ground transportation around cruise ports — reservations, dispatch runs, and fleet and driver management — migrated from a legacy CodeIgniter codebase to Laravel 12. A public Angular booking widget with live map-based pickup selection lets customers build a trip and get a quote without touching the admin side.

  • 244 database tables, 85 Eloquent models — a mature system, not a prototype
  • B2B multi-tenant hierarchy: content providers, regional and affiliate operators, agents
  • Embeddable Angular booking widget with live Google Maps pickup selection
  • Role-based access gating both page-level routes and in-page actions

SOFTWARE GREENFIELD BUILD

BuilderHub2 — Client, Offer & Invoicing Platform

An admin platform built from scratch for a construction and renovation firm: client and site management, an interactive offer builder with live pricing from a service catalog, project tracking through to completion, and invoicing built for full compliance with Bulgarian tax authority (NAP) requirements.

  • Interactive offer builder — category → service autocomplete, auto-filled pricing, running totals, PDF export
  • Invoicing built for NAP compliance from day one: gapless sequential numbering, immutable once issued, credit/debit notes for corrections
  • One connected workflow: inquiry → client → offer → project → invoice
  • Role-based access down to the page and action level

Build Help — Site, Crew & Budget Tracking

A system for a small construction crew that replaced a hand-calculated Google Sheet: work days, materials and payments per site, with a dashboard that shows what is spent, what is still owed to workers and suppliers, and warns before a budget is exceeded.

  • Live dashboard per site — spend vs. budget, amounts owed to workers and suppliers, colour-coded overrun warnings
  • Mobile-first installable PWA with push notifications, so foremen log days and purchases right on site
  • Owner and foreman roles — foremen enter data, owners see the money
  • Import of existing Excel/CSV data and CSV export; deployed on Docker and on Windows/IIS hosting

WHY US

What you get working with us.

Hardware to cloud, one pipeline

We design the sensor, write the firmware, and build the platform that turns its data into decisions — no handoff between separate vendors.

Legacy modernization

Comfortable untangling decade-old systems and migrating years of production data without losing a row — or a client.

Real production experience

We deploy to and debug real hosting environments — including the notoriously fussy Windows/IIS stack — not just localhost demos.

Bilingual delivery

Interfaces and support in English and Bulgarian from day one — built into the stack, not bolted on afterward.

TOOLBOX

Technology we build with.
