I'm a backend-first builder and software architect-in-progress with 8+ years of experience designing cloud-native systems, building internal tools, and experimenting with AI in real-world apps. Currently at PayPal, I design scalable backend systems and drive AI adoption in engineering workflows. Previously, I architected a general ledger engine processing over 10 million TPM and led successful transitions from monoliths to microservices in banking CRM platforms. What excites me today: Integrating AI with backend systems (LangChain, RAG, evals) Building tools that improve dev velocity (CI/CD, release automation) System design at scale (APIs, consistency trade-offs, resilience) I document what I build at vignesh.page and occasionally publish my experiments on GitHub and Dev.to.
