Approach
A specialist, not a jack-of-all-trades
Custralis is specialist bespoke development for SMEs: solid back-end and application security, with a clear, transparent method. You always know where things stand, and it starts from what you already have instead of throwing it away.
Who is behind it
Behind Custralis is a senior developer, with years of experience in back-end (Java, Spring Boot) and application security, not a jack-of-all-trades software house. The difference is not doing everything, but doing well the few things that matter: building bespoke software, integrating and modernising what is already there, including legacy systems and the AS/400, with security built in from the first line. Better a specialist than a generalist.
How the work unfolds, together
From the first contact to ongoing support.
Listening and analysis
It starts from your goal, your real constraints and the systems you already use, before writing a line of code.
Clear proposal
Solution, timeline and cost presented transparently, without needless jargon.
Step-by-step development
Built in verifiable blocks: you see the progress, no “black box” effect.
Testing and security
Every part is tested and secured by design, with OWASP checks, before going live.
Release and support
Careful launch and ongoing assistance: the software stays reliable.
Principles
- Integrates with what you already have, including legacy systems and the AS/400, instead of replacing it.
- Security and privacy by design, not as an afterthought.
- Bespoke: no off-the-shelf solutions.
