SkyPlainWhat we do
We cover the whole software lifecycle — from architecture and development to launch, monitoring and maintenance.
Custom software development
Web applications, SaaS platforms, APIs and internal tools — greenfield or extending what you have.
We design and implement complete solutions: user interface, business logic, database and integrations with external systems.
We work mostly in the TypeScript ecosystem (React, Node.js, Prisma) with relational databases, but we pick the technology for the problem, not the other way round.
Every project ships with automated tests, end-to-end coverage of the critical flows and CI/CD from day one.
Cloud and DevOps
Azure infrastructure, containers, CI/CD, monitoring and cost optimisation.
We set up production environments on Microsoft Azure: container apps, managed databases, static sites, networking and identity — with network isolation and firewall configuration when needed.
Infrastructure is described as code and delivery is automated through GitHub Actions or Azure DevOps pipelines, with separate QA and production environments.
We optimise cost and add monitoring, logging and backups so the system keeps running when nobody is watching.
Systems and native programming
C, C++ and Rust — performance, multimedia, GPU, embedded devices and close-to-the-metal code.
When JavaScript is not enough: real-time audio and image processing, GPU compute, network protocols, firmware for microcontrollers and IoT devices, integration with smart devices over the local network, desktop applications and libraries for other teams.
We have hands-on experience with the OpenGL/Vulkan/WebGPU stack, multimedia libraries and cross-platform build systems.
We use Rust where memory safety and predictable performance are essential — from desktop tools to embedded devices. The same C/C++ code can be compiled for the web via WebAssembly.
AI and LLM integration
Agents, document automation, search over your own data and in-app assistants.
We embed large language models into existing products: document classification and extraction, search with cited sources, assistants inside the user interface.
We build agentic workflows with clear boundaries, quality evaluation and cost control — no "magic" nobody can explain.
Our AI features are testable: deterministic model stand-ins in CI mean every change is verified quickly, cheaply and reproducibly.
Consulting and architecture
Technical due diligence, code review, technology selection and migration planning.
An independent assessment of your existing system: code quality, security, scalability, cost and risk — with a concrete plan of what to change and in which order.
We help with choosing technologies and vendors, defining the architecture of new products and establishing engineering practices in your team.
We also act as a fractional CTO for companies that do not yet have technical leadership.
Regulated and multilingual domains
Software for legal, financial and compliance processes — with audit trails and multiple languages and scripts.
Experience with applications where every action must be recorded, every document versioned and access strictly controlled.
We support multiple languages and scripts (including Serbian Latin and Cyrillic) as a built-in part of the product, not an afterthought.
We turn business processes that live in spreadsheets and email today into reliable, verifiable systems.
GIS and geospatial data (US patent co-inventors)
Interactive maps and spatial analysis over large volumes of data arriving live.
We tidy up location data coming from different systems and tie it to the geography it belongs to, so it can be reliably filtered and computed on.
We build maps that stay fast and readable even with millions of objects on screen, and that can show how the picture changed over time.
Spatial databases and indexes (PostGIS) on the server, Leaflet and MapLibre in the browser. In this field we are also co-inventors of a US patent.
User interfaces for financial markets
Desktop and web applications for financial market professionals — dense screens with data that changes by the second.
We build screens where users follow many instruments at once and arrange the layout themselves, without slowing down while data keeps streaming in.
Next to every number we show where it came from and how it has moved, so analysts and operations teams can check values quickly and act on outliers.
Desktop clients in Java (Swing, JavaFX), web applications in React and TypeScript, together with Electron, AG Grid and Highcharts.
A clear process, no surprises
- Conversation — We listen to the problem, not a feature list. We ask what changes in your business once the solution is live.
- Proposal and estimate — A written proposal with scope, architecture, timeline and price. Phased, so you see the first value quickly.
- Iterative delivery — Short cycles, a working version available from the first week, transparent progress tracking.
- Launch and support — Production with monitoring, documentation and knowledge hand-over. We stay with you for as long as you need.
