About
A small company with senior hands
RDZZ LTD does two things: AI and data architecture work for teams with messy systems, and its own software products. It is small on purpose, so you deal with the person doing the work.

The founder
Senior architecture, without the headcount
John Mikel Regida
Founder · Data & platform architect
Engagements bring senior, hands-on architecture experience to teams that need direction before they commit to a larger build: the kind of judgement that's usually locked up in a full-time principal hire.
- Senior backend, platform and data architecture across regulated and data-heavy environments.
- Production experience with TypeScript, Node.js, Java, .NET, PostgreSQL, SQL Server, Elasticsearch/OpenSearch, AWS, Azure, GCP, Kubernetes, Terraform, CI/CD, observability and testing.
- Hands-on with semantic models, ontology-style data structures, retrieval workflows, LLM and RAG evaluation, and keeping all of it supportable in production.
- Used to guiding engineers, product, data teams and stakeholders through ambiguous platform decisions.
