Enterprise engineering and product teams building autonomous coding, research, financial analysis, and customer operations agents powered by Anthropic's frontier models frequently search to hire a freelance Anthropic Claude (Claude 3.7 Sonnet, Extended Thinking, Prompt Caching, Batch API & Model Context Protocol) programmer. I am Aldian Fazrihady, a Senior Freelance AI Application Engineer and Full Stack Programmer available via Upwork.
Core Anthropic Claude & Agent Engineering Capabilities
- 90% Cost Reduction via Anthropic Prompt Caching: Structuring `cache_control: {"type": "ephemeral"}` breakpoints across large system prompts, few-shot examples, tool definitions, and multi-hundred-page document contexts to cut input token costs by up to 90% and time-to-first-token (TTFT) by up to 80%.
- Extended Thinking & Multi-Step Tool Use: Calibrating thinking token budgets for complex legal, clinical, mathematical, and code-generation reasoning combined with deterministic Pydantic tool schemas.
- Model Context Protocol (MCP) Host & Server Architecture: Connecting Claude agents safely to PostgreSQL, GitHub, Jira, Slack, FileMaker, and enterprise ERPs.
