Everything you need to ship a digital product
From a greenfield MVP to scaling and modernising an existing platform — we cover frontend, backend, mobile and the engineering practices around them.
Web applications
Modern, fast and accessible frontends built with React and Next.js. Pixel-perfect implementation of Figma designs, strong TypeScript typing and performance optimisation (streaming, memoisation, lazy loading).
React & Next.js
TypeScript
Material UI, CSS-in-JS
Redux, Apollo GraphQL
Backend & APIs
Robust, well-tested backends and integrations. REST and GraphQL APIs, authentication (Keycloak, NextAuth), database design and query optimisation on PostgreSQL and MySQL.
Node.js / Express
Python / Django
Java / Spring Boot
C# / ASP.NET Core, Go
Mobile applications
Cross-platform iOS and Android apps with React Native, sharing business logic and design system with your web product. Published and maintained under our own developer accounts or yours.
React Native
iOS & Android
App Store / Google Play delivery
Push, offline, analytics
Cloud, DevOps & real-time systems
Deployment pipelines, containerisation and cloud infrastructure. Experience with real-time data ingestion (WebSockets, GraphQL subscriptions, SIP telephony) and preparing data for machine-learning and LLM-based analysis.
AWS
Docker, CI/CD
WebSockets & subscriptions
ML / LLM data pipelines
Legacy modernisation & performance
Refactoring legacy code bases, migrating to typed stacks (TypeScript, generated OpenAPI / GraphQL types), improving Core Web Vitals and database performance without stopping the business.
Audits & refactoring
Type-safe migrations
Core Web Vitals
DB optimisation
Tech leadership & team augmentation
Senior engineers who plug into your team: architecture decisions, code reviews, mentoring less experienced developers and setting up testing and quality standards (Jest, React Testing Library, Storybook).
Tech lead as a service
Code reviews
Testing strategy
Storybook & design systems
A proven, modern stack
We pick boring-in-a-good-way technologies with strong ecosystems, then apply them with discipline: strict typing, tests and measurable performance.

Industries we have delivered for
Over ten years of production work across regulated and performance-critical domains, mostly as part of international remote teams.
01
Healthcare & medical platforms
Highly typed, secure web applications for hospitals and medical software vendors — patient-facing portals, clinical tooling, GraphQL APIs on top of legacy data.
02
Fintech & banking
Frontend components for banking applications with a strong focus on unit and integration testing.
03
Industrial IoT & automation
Real-time single-page dashboards for smart industrial systems: live charts, WebSocket subscriptions, caching and heavy performance optimisation.
04
Telecommunications & fraud detection
Real-time call-ingestion services capturing audio and metadata and preparing them for LLM-based analysis.
05
Automotive, education & enterprise tools
Car configurators, university platforms, internal password managers and other end-to-end business applications.
About ml-code
ml-code s.r.o. is a software engineering company based in Košice, Slovakia, founded in 2023 by Miroslav Ledecký — a full-stack engineer with more than ten years of professional experience building web and mobile products for clients in Slovakia, the Czech Republic, Switzerland and the United States.
We work with startups, scale-ups, software agencies and established companies that need senior engineering capacity: either delivering a complete product end to end, or joining an existing international team as a frontend, backend or full-stack engineer and tech lead.
Our approach is pragmatic: strongly typed code, automated tests, code reviews and measurable performance. We communicate in English and Slovak, work remotely across European and US time zones and take long-term ownership of what we ship.
Type-safe by default
TypeScript end to end, generated API types, validated forms.
Performance matters
Streaming, memoisation, lazy loading, database optimisation.
Quality is a process
Tests, code reviews, Storybook, CI/CD — not an afterthought.
Long-term partners
We maintain and evolve products for years, not weeks.
