Reliable systems for the agentic era.
We help teams design and build AI agent platforms, distributed systems, and backend infrastructure that hold up in production — durable, observable, and correct under failure.
Deep backend expertise, applied where it matters.
Hands-on, senior-level engineering — from architecture reviews to shipping production code alongside your team.
AI Agent Systems
Production architecture for LLM agents: tool orchestration, long-running and resumable workflows, state management, evaluation, and guardrails that keep agents dependable at scale.
- Agent orchestration
- Durable execution
- Tool / MCP integration
- Evals
Distributed Systems
Consensus, replication, and workflow engines designed for correctness. We've built Raft-based orchestration and Temporal-style durable execution for mission-critical workloads.
- Raft / consensus
- Workflow engines
- Fault tolerance
- Event-driven design
Backend Architecture
System design, scalability, and reliability reviews. Clear trade-off analysis, migration plans, and hands-on implementation of high-performance backend services your team can own.
- System design
- Architecture review
- Backend services
- Performance
- Team mentoring
Start small. Go deep when it matters.
Engagements typically begin with a fixed-scope review, then continue into implementation or ongoing advisory as needed.
Agent Reliability Review
A focused assessment of your AI agent or backend system before it fails in production.
- Architecture & failure-mode analysis
- State, retries, idempotency & recovery review
- Scalability and cost hotspots
- Written report with a prioritized fix roadmap
Implementation Sprint
Hands-on engineering to design and ship the critical pieces alongside your team.
- Durable workflow & agent orchestration
- Distributed system design and build-out
- Observability, testing & production hardening
- Knowledge transfer to your engineers
Fractional Staff Engineer
Senior technical leadership on call, without a full-time hire.
- Architecture decisions & design reviews
- Code review for critical paths
- Hiring and technical interview support
- Regular check-ins with your team
How we work.
Small, focused engagements with a senior engineer directly involved from day one.
Discover
Understand your goals, constraints, and the system as it really runs today.
Design
Propose architecture with explicit trade-offs, failure modes, and a phased plan.
Build
Ship production code with your team — tested, observable, and documented.
Hand off
Leave your engineers confident to own, operate, and evolve the system.
Built by a staff-level systems engineer.
Warm Springs Labs was founded by Frankie, a staff-level backend engineer with about 15 years of experience building large-scale distributed systems.
Most recently at a global financial institution, Frankie built a durable workflow orchestration engine using Raft-based consensus and Temporal-style patterns — the same reliability principles that today's AI agent platforms need.
We bring that rigor to teams building the next generation of software.
