Liam F.
✓ Vetted CrafterStaff Software Engineer – Integrations & Performance
I build integrations and optimise them — APIs that connect and perform.
About
I build integrations and optimise them. I have connected 12+ products to external services and improved API performance by 60% in several engagements. I specialise in REST APIs, webhooks, caching, and query optimisation. Cursor helps me refactor integration code and profile performance. I work with TypeScript, Node.js, React, and PostgreSQL.
My focus is on integrations that perform: connection pooling, response caching, and efficient data sync. I have built integration platforms for e-commerce, optimised slow API endpoints, and designed event-driven architectures. Good integrations are fast and reliable.
AI Expertise
Notable Projects
Mining Operations Report Generation Agent
Built a LangGraph agent for a Pilbara mining operation that collects data from 12 SCADA systems, sensor APIs, and maintenance logs, then generates structured daily operations reports. The agent follows a defined workflow with validation checkpoints and human review before distribution.
✓ Report preparation time reduced from 3.5 hours to 20 minutes daily; zero missed daily reports in 8 months of operation; safety incident correlation analysis now included in every report.
Regulatory Compliance Monitoring Agent
Designed a CrewAI multi-agent system for ASIC regulatory compliance monitoring for a financial services firm. Agents monitor regulatory updates, map changes to internal policies, flag gaps, and draft policy update proposals with full audit trail and human approval workflow before any changes are finalized.
✓ Reduced time to identify regulatory change implications from 2 weeks to 3 days; compliance team capacity freed up by 40% for higher-value advisory work.
Agent Observability Dashboard
Built an observability platform for LangGraph agents: real-time state visualization, tool call logging, cost tracking per agent run, error analysis, and performance benchmarking. Built with React frontend and FastAPI backend with LangSmith integration.
✓ Internal tool adopted by 4 engineering teams; identified and resolved 3 agent infinite-loop bugs before production deployment; reduced mean time to debug agent failures from 2 hours to 15 minutes.
