I build zero-downtime, distributed, and highly secure infrastructure for enterprise AI and SaaS platforms.

My work sits where product urgency meets operational risk: high-throughput backends, AI/RAG systems, cloud-native platforms, and engineering operating models that can survive real production load.

• Fractional CTO for early and growth-stage product teams
• Cloud-Native Systems Architect for distributed backend and platform work
• DevSecOps Engineer for production hardening, delivery automation, and observability
• AI Infrastructure Engineer for RAG, semantic search, model routing, and token-cost optimization

• Production-grade TypeScript/NestJS architectures with strong domain boundaries
• Event-driven systems using PostgreSQL, Redis, BullMQ, Kafka, and NATS-style messaging
• Reliable AI pipelines with vector search, semantic caching, evaluations, and fallback paths
• Infrastructure that makes latency, failure modes, and cost visible before they become incidents

• Architecture decisions documented before abstractions harden
• Tests focused on contracts, failure modes, and business-critical flows
• Observability built around P95/P99 latency, error budgets, queue depth, and saturation
• Security treated as a design constraint: least privilege, secrets hygiene, audit trails
• Delivery process based on small PRs, conventional commits, CI, and production-minded reviews

I am a fit when the work needs more than feature delivery:

• You are shipping an AI or SaaS platform where reliability affects revenue or trust.
• Your system is growing past the point where ad hoc backend decisions still work.
• You need a technical partner who can design, implement, and explain the tradeoffs.
• You want production architecture, not a demo that collapses under real users.
