Tech problems holding back your growth
Operational & ERP Chaos
Custom ERP systems that are hard to maintain, audit, and scale.
Slow & Costly Infrastructure
Legacy infrastructure limiting growth, security, and continuity.
Vendor Lock-in Risk
Critical knowledge concentrated in one person or vendor.
Growth Without IT Governance
Growing companies without strategic IT direction or clear governance.
Services
Fractional CTO Services
Strategic leadership and executable architecture for companies where technology is already too critical to improvise.
ERP Modernization
Modernizing Odoo and legacy ERPs without disrupting the business's operational heart.
Outcome: cleaner processes, fewer manual exceptions, and greater operational control.
Cloud Architecture
Designing resilient, observable, secure, and cost-governed AWS and Azure foundations.
Outcome: infrastructure that enables growth instead of holding it back.
DevOps & Infrastructure
Pipelines, infrastructure as code, and deployment governance for critical systems.
Outcome: more reliable, traceable releases with fewer production surprises.
AI Automation
AI agents and automations applied to workflows with measurable gains in time, cost, or quality.
Outcome: less repetitive work with human supervision and real metrics.
Cybersecurity & Governance
Pragmatic controls, risk visibility, continuity, and ISO 27001 as an operational framework.
Outcome: lower exposure, greater accountability, and executive confidence.

ColdTemplar Lab: AI infrastructure with production discipline
The lab validates the same principles used in enterprise consulting: first stabilize, then automate, and later optimize. It connects local AI agents, workflow orchestration, observability, and recoverable infrastructure in a controlled platform.
What this means for your business: we don't recommend any technology we haven't run in production ourselves. No demos. No promises. Only what we've already proven.
