I’m Jiaqi Li, a senior full-stack engineer in Espoo, Finland, with 10+ years of experience building production-quality systems for consumer finance and telecom. I’ve delivered end-to-end solutions across backend architecture, data ingestion, privacy/compliance-aligned integrations, and scalable services in cloud and containerized environments. In recent roles at Nokia and Ericsson, I’ve built and optimized network/analytics services and LLM-based workflows (RAG, orchestration, and latency/accuracy improvements), with strong attention to observability, reliability, and OAuth2-backed API security. I also enjoy collaborating cross-functionally—guiding junior developers, partnering with security teams, and instrumenting systems so they’re easier to operate and troubleshoot in high-stress production scenarios.…I’m Jiaqi Li, a senior full-stack engineer in Espoo, Finland, with 10+ years of experience building production-quality systems for consumer finance and telecom.
