12,000
messages unblocked
Invoicing pipeline unblocked
One high-volume transaction (~12,000 messages) starved all other invoicing for 50+ minutes. Redesigned the JMS/ActiveMQ topology into isolated, concurrency-tuned consumer pools.

What I do
Two practices, one engineer
Deep, proven systems engineering — and the integration rigor that makes AI actually work in production. Most consultancies do one. The combination is the point.
⬡
Systems & Integration
The work I've done for 15 years: keeping mission-critical, message-driven enterprise platforms running under real load.
Incident response & RCA. Critical failures diagnosed, resolved, and documented with an executive-ready root cause.
Integration platforms. Camel, ActiveMQ/JMS, Karaf/ServiceMix — architecture, tuning and deep troubleshooting.
Database & performance. PostgreSQL lock contention, query and index optimisation, zero-downtime migrations.
Infrastructure & DevOps. Linux, Kubernetes/K3s, Docker, CI/CD and monitoring that stay up under pressure.
✦
AI Consulting & Integration
AI that ships into production. Not models in a notebook — AI wired safely into your real systems and data.
AI readiness assessment. Where can AI realistically deliver ROI? A prioritised, no-hype roadmap from your data and workflows.
AI integration & middleware. Securely connect LLMs and agents to your systems and APIs, with RAG so answers are grounded in your own knowledge.
Agentic workflow automation. Beyond chatbots: agents that do real work across your systems, with guardrails and a human in the loop.
Production reliability for AI. Monitoring, evaluation and the operational rigor that keep AI stable once it's live.
Proof
Results, not promises
Anonymised outcomes from real production systems at Fortune-500-scale companies. Client and system details removed — the engineering is real.

faster portal search
Portal search, 70s → 5s
An enterprise portal's order search ran a full-table scan with no tenant filter. Diagnosed the missing index and built a composite index online — zero downtime.
Restored
Fortune-500 prod outage
Production outage recovered
A Fortune-500 customer's production environment exhausted its JVM heap and went down. Root-caused the memory growth, restored service, and added guardrails against recurrence.
44,000
line invoice made usable
A 44K-line invoice, batch-fetched
An N+1 query fired one database call per invoice line; the largest invoices (100,000+ lines) were unusable. Redesigned the access path to batch-fetch.
167
orders correctly routed
A cross-thread cache bug, mapped
A worker thread read a stale second-level cache entry after another committed, misrouting 167 orders. Produced the multi-thread analysis pinpointing the cache-isolation boundary, and the fix.
100%
consistent reprocessing
EDI idempotency corrected
A repeated EDI despatch message left quantities silently wrong — an ignored field in the update path. Traced the idempotency gap to the exact unmapped field and corrected the logic.
How I work
Senior hands, your way
Every engagement follows the same discipline: diagnose from evidence, fix with minimal risk, document so the result holds. Four ways to bring me in:
01
Incident & RCAShort, intense engagements. I diagnose, fix, and hand over a clear root-cause report.02
Fractional / retainerOngoing senior ownership of a platform or AI system — there when it matters.03
Advisory & reviewArchitecture reviews, health checks, and performance or AI-readiness audits.04
Project deliveryScoped builds — an integration, a migration, or an AI workflow shipped end-to-end.About
The engineer other engineers escalate to
I'm Renato — an integration and platform engineer with 15+ years keeping mission-critical enterprise systems alive. Today I'm the final escalation point (L3) at a global supply-chain SaaS platform used by Fortune-500 companies: the incidents that reach me are the ones no one else could resolve.
I work through Safe Space Cloud, my independent consultancy. Based in Rotterdam and relocating to Valencia, I take on remote and on-site work across Europe — bringing the same production rigor to integration, data, infrastructure and AI.
I also run a production-style Kubernetes platform on my own hardware (K3s on Proxmox, a dozen self-hosted services) — hands-on proof of the infrastructure skills I bring to client work.
