Automotive Data · ERP · Healthcare Systems
The verticals most agencies won’t touch — auto parts data, ERP, and regulated healthcare.
We’re a Vietnamese engineering collective built for the boring, high-stakes systems: OEM catalogs with millions of cross-references, construction & retail ERPs running real operations, and clinical software shipped under ISO 13485.
Aggregated experience from Vireon Labs, Aratech Vietnam & Gosei Vietnam JSC — serving EU & APAC clients.
Who we are
An engineering collective backed by three Vietnamese companies
Vireon Labs aggregates senior engineering capacity from three established teams so EU clients get continuity, accountability and a single delivery contract.

Services
What we’re actually good at
Custom software, data platforms, and regulated systems — delivered by the same senior engineers from discovery through second-year support. No project managers translating between you and a junior pool.
Why us over the next ten agencies on your list
We’re narrow on purpose. If your system is mostly a marketing site or a CRUD app, there are cheaper teams. If it has to be correct, audited, and still alive in five years — that’s us.
Domain depth, not generalist devs
We’ve shipped OEM catalogs with millions of SKUs, ERPs running real construction projects, and laboratory systems used in patient care. We don’t learn your industry on your budget — we walk in already speaking it.
Three companies, one accountable team
Vireon Labs aggregates senior capacity from three established Vietnamese companies under a single contract and a single PM. You get the bench depth of a large agency without the handoff chaos — and we can’t hide a missed sprint behind a subcontractor.
Built for systems that get audited
Our healthcare work ships under ISO 13485 quality processes; our ERP work survives finance and inventory audits. That discipline (traceable requirements, reviewed code, documented changes) carries into every project — not bolted on at the end.
EU-hour squads, written communication
Senior engineers overlap the European workday in writing — specs, decisions, and tradeoffs live in your tools (Linear, GitHub, Notion), not in WhatsApp threads. Async by default, sync when it actually moves the project.

Testimonials
What Our Clients Say
“Vireon Labs rebuilt our auto parts catalog from scratch. They normalized 10M+ supplier records and dropped our search latency below 700ms. Fitment accuracy jumped 38% — fewer returns, happier dealers.”
Markus Hoffmann · CTO · EU Auto Parts Group
“We tried two standard ERPs before working with Vireon Labs. Their team understood Bau workflows and delivered a system our site managers actually use. Approvals went from 5 days to under 1.5.”
Andreas Becker · Head of Operations · Bau Nord GmbH
“Rolling out promotions across 120 stores used to take days. With the new pricing engine the team ships campaigns in under two hours. The platform stays stable through peak traffic.”
Lena Park · VP Retail Technology · Retail Chain APAC
“Their healthcare team got Westgard QC rules and ISO 15189 audit trails right on the first iteration. That level of regulated-software discipline is rare offshore.”
Dr. Trinh Nguyen · Lab Director · Aratech Medical (partner)

Security & Compliance
Built for regulated EU workloads
Our engineering practice is shaped by clients in healthcare, automotive supply chain and construction ERP — domains where governance and traceability are non-negotiable.
GDPR awareness
EU data protection considerations baked into discovery: data minimisation, lawful basis, DPA-ready contracts and EU-region hosting on AWS / Azure when required.
Secure SDLC + OWASP
Threat modelling, dependency scanning, OWASP ASVS-aligned reviews, and CI checks for secret leaks, vulnerable packages and misconfigurations before merge.
RBAC & least-privilege
Role-based access control, audit-grade authentication (SSO/OIDC), and infrastructure access via short-lived credentials — no shared production logins.
Audit logging & traceability
Structured audit trails for sensitive actions (clinical / financial / approvals), tamper-evident log shipping, and retention policies that match client compliance regimes.
Formal certifications (ISO 27001, SOC 2) are not yet on our wall — we partner with clients who carry them and operate inside their security and audit requirements.
