Claude API developers who ship with prompt caching, tool use, computer use, and Message Batches. We pick the right model (Opus 4.7 for hardest reasoning, Sonnet 4.6 default, Haiku 4.5 for bulk), turn on caching on the first day, and wire MCP integrations where they fit.
Claude API engagements cover the seven places Claude production builds typically stall without senior engineers: prompt caching never enabled (which alone is worth 90% cost reduction on cached segments), no cache_control blocks structured into the system prompt, tool-use calls timing out or looping, Opus used where Sonnet would handle the work, Claude Agent SDK underutilized, no observability on token spend, and confusion between the direct Anthropic API, Bedrock, and Vertex paths. We ship on Claude end-to-end: Opus 4.7 for the hardest reasoning, Sonnet 4.6 for default, Haiku 4.5 for classifiers and bulk. Every project ships with cache_control, Message Batches (50% off for non-urgent workloads), tool use, and MCP where the client surface benefits.
Claude is our default recommendation for quality-sensitive text — code, long reasoning, structured analysis, nuanced writing. The failure mode isn't that the Anthropic SDK is hard; it's that production features (prompt caching, Batch API, model routing, tool-use retry logic) sit a layer above the 'hello world' example. Teams ship without them and then spend a quarter digging out. This page is for hiring senior Claude engineers who turn those features on from day one.
Anthropic's cache_control blocks cut cost 90% on cached reads — the single highest-leverage lever on any Claude bill. Most builds we audit have never set a cache_control block. The fix is usually under an hour; the savings land immediately.
cache_control works only when the cached prefix is stable across requests. Templating user-specific data into the system prompt silently kills the cache. We restructure the prompt so the cached portion actually repeats request-over-request.
Opus is for the hardest reasoning — multi-hop, novel analysis, code that requires planning. Most chat, drafting, extraction, and classification tasks are Sonnet territory. Model routing typically cuts cost 50–70% without a quality regression.
Tool-use production patterns require: idempotent tool handlers, retry with repair on malformed inputs, max-step caps, and a kill-switch for runaway sessions. Ship without these and a single stuck tool call can cost $50+.
Non-urgent workloads (eval suites, nightly summaries, bulk content generation) run 50% off on Message Batches. The API is a near drop-in; most teams haven't even heard of it.
Skills, memory, subagents, context management — the Agent SDK does the heavy lifting that teams usually hand-roll. We migrate hand-rolled loops to the Agent SDK where it fits, and keep LangGraph where the graph is the right shape.
Direct Anthropic API is fastest to new features. Bedrock is the AWS compliance path. Vertex is the GCP path. Each has different model availability, different pricing, different BAA coverage. We map your compliance and infra needs to the right path on the scoping call.
The rescue path we run on every Claude engagement. Fixed price, fixed scope, no hourly surprises.
Send the repo. We audit the Claude app — auth, DB, integrations, deploy — and return a written fix plan in 48 hours.
Patch the highest-impact failure modes first — the RLS hole, the broken webhook, the OAuth loop. No feature work until production is safe.
Real migrations, signed webhooks, session management, error monitoring. Tests for every regression so Claude prompts can't re-break them.
Deploy to a portable stack (Vercel / Fly / Railway), hand back a repo your next engineer can read, and stay on-call for 2 weeks.
