We modernize legacy applications, connect existing systems and build reliable software around real operational processes — without forcing a full replacement of what already works.
The hardest software projects rarely start with a blank page. They start with existing users, old data, undocumented rules, integrations and a system that cannot simply be switched off.
Modernize aging .NET, desktop and internal business applications while preserving critical behaviour, data and workflows. We favour staged migration over risky big-bang rewrites.
Connect APIs, databases, ERP systems, scanners, hardware and existing backends. The goal is to make systems work together without replacing the entire environment.
Software for manufacturing, logistics, warehousing and internal operations where reliability, traceability and clear failure handling matter more than flashy features.
Code is only one part of modernization. The real system also includes data, workflows, hardware, users, operational constraints and years of accumulated decisions.
We map how the system is actually used before proposing architecture or migration steps.
You work directly with the person responsible for technical decisions and delivery — without layers of account management.
Source code, access and documentation remain part of the deliverable. The system should be maintainable beyond one supplier.
Migration, diagnostics, monitoring and support after go-live are treated as engineering work, not an afterthought.
Some client names and implementation details cannot be published. These examples show the type of technical work where TechMolvia is most useful.
Integrating Data Matrix scanners with application logic, persistence and diagnostics for workflows where physical operations and software must stay in sync.
Mapping existing behaviour, dependencies and data before replacing individual parts with supported technology and a maintainable architecture.
A new API, database layer or user interface connected to an existing backend, device or business system instead of replacing the whole stack.
Client projects are not our only source of engineering experience. Building our own products keeps product decisions, UX, implementation and delivery under the same responsibility.
FluentTales is an in-house product developed by TechMolvia. It covers the full path from product concept and UX through the Android application, backend services and the release process. It is a practical example of end-to-end product engineering rather than a separate service offering.
We do not sell a giant technology catalogue. These are the areas we are most comfortable owning end to end.
C#, modern .NET, ASP.NET Core, desktop applications and incremental migration from older .NET codebases.
APIs, relational databases, backend services and the boundaries between old and new systems.
Software that needs to exchange data with scanners, devices, line-side systems or other software outside a clean greenfield environment.
The same engineering capability can support a business that owns a legacy system or a software team that needs experienced capacity for a difficult part of a project.
For established businesses with internal software, operational workflows or integrations that have become hard to maintain.
For software companies, integrators and internal teams that need focused senior engineering without building a permanent team for one difficult area.
Modernization projects become expensive when assumptions survive too long. We start small, verify the system and then scale the implementation.
Review the current application, data, integrations, constraints and operational workflow. Define what must remain stable.
Define the target architecture and implement a small but real vertical slice before committing to a large rewrite.
Move capability step by step, with data migration, diagnostics, documentation and operational support included in the plan.
.NET is our strongest engineering area, but modernization and integration projects usually involve databases, APIs, hardware and systems written in other technologies as well. We evaluate the environment as a whole.
Yes. We can own a defined technical area, work alongside an internal engineering team or integrate with an existing vendor where responsibilities are clear.
No. In many cases a staged replacement is safer and more economical. We prefer to keep stable parts in place while removing specific technical or operational constraints.
TechMolvia is based in Bratislava, Slovakia and works remotely with clients across Europe. On-site work can be arranged when understanding the physical operation is important to the project.
