Custom software
Web and mobile applications designed around a concrete process, users and data.
Software & product engineering
I build systems that connect processes, data and devices.
I design and develop web applications, research systems and integrations. I combine Laravel and React with automation, AI, HL7/FHIR, BLE and device layers when a product needs to go beyond the interface.

The company
Technology is a tool. The problem to solve remains the starting point.
Strefabadan.pl is Lukasz Szemiako’s software business, developing its own products and helping teams design, integrate and maintain software.
The core of the work is full-stack development with Laravel, React and Vue, data systems and Docker-based infrastructure. The scope covers analysis, architecture, implementation, testing, deployment automation and continued product development.
I treat AI modules, medical integrations and devices as part of a concrete process, with controlled data, clear responsibilities and verifiable outcomes.
I use a self-hosted, containerized Git/Forgejo and CI/CD stack. For a client, I can design and launch a similar process in technology suited to their needs, in the cloud or on their own infrastructure, with monitoring, backups and access control.
Lukasz’s portfolioSelected certifications
Certifications complement project experience and can be verified with their issuers.
Scope of work
Support matched to the product stage.
From technology consulting and architecture choices, through system development, to integrations and a complete client-owned environment.
System and data integration
APIs, HL7/FHIR, imports, synchronization, queues and secure data exchange between services.
AI and automation
Practical AI modules, computer vision, knowledge workflows and automation with output quality checks.
Technology consulting and product development
Selecting architecture, technologies and a delivery model, then moving from a concept to a maintainable product.
Git, CI/CD and infrastructure
Private Git/Forgejo, Docker containers, CI/CD pipelines, cloud or on-premise environments, monitoring and backups.
Quality and security
Access control, privacy, auditability, testing and resilience improvements for existing systems.
Products and initiatives
Projects currently in development.
Each project addresses a different problem, but all of them focus on a useful process, trustworthy data and room for further development.

Case study · DevOps
A custom infrastructure management panel.
I design not only the product itself, but also operator tools tailored to the team: starting services and containers, readiness monitoring, integration diagnostics, logs and safe maintenance actions in one place.
These demonstration views are based on a working solution. Project names, addresses, identifiers and operational data have been anonymized.
Environment overview
A quick view of services, containers, warnings and development readiness.
Application service controls
Start, restart, stop, logs, local addresses and response-time measurements.
Diagnostics and logs
Application readiness, integration status and process output in one place.
Collaboration
From a focused module to ownership of the complete flow.
The work can cover a new product, taking over a system, a specific integration, technology consulting or creating the client’s infrastructure. Scope is shaped by risk and product stage.
Product development
Ongoing work with a product owner or team: priorities, implementation, releases and maintenance.
Integration or module
A clearly bounded scope: API, data import, AI module, reporting, payments or device communication.
Consulting and stabilization
Assessing architecture and technology, diagnosing issues and planning improvements to security, performance or delivery.
Client infrastructure
Designing and launching Git, CI/CD, containers, cloud or on-premise infrastructure, with documentation and control retained by the client.
