Solution Architect | Core Banking Modernization for AMEX, BMO & Goldman Sachs | API-First | Kafka (EDA) | Gen AI / RAG | Cloud | Deep IC Technical Track, 20+ Yrs

About

I bring 20+ years (with 13+ years at FIS) in tech - from building enterprise software to architecting the platforms that now power Tier-1 banks globally. I've designed enterprise-scale platforms for some of the most demanding clients in banking - AMEX, ANZ, BMO, Goldman Sachs, and Citizens Bank. My work spans API-first architecture, event-driven systems, cloud-native integration, fintech platforms, and AI - but the common thread is always the same: turning tangled, legacy-heavy landscapes into platforms that scale cleanly and deliver measurable business outcomes. Recent work that reflects this: • Replaced batch synchronization with event-driven, Kafka-based integration between FIS MBP and BMO's Enterprise Customer Information File — cutting operational latency by over 99% • Designed an API ecosystem of 200+ enterprise APIs across deposits, payments, cards, lending, and risk for Tier-1 banks on Azure and FIS Cloud • Built MBP SelfServe, a GenAI/RAG-powered knowledge assistant that unifies Wiki, JIRA, SharePoint, and release documentation into a version-aware conversational interface — delivering an estimated $1M+ in annual business benefit • Drove adoption of FIS Code Connect, our enterprise API Gateway platform, delivering 193% ROI and ~$946K in net business benefit over three years • Led the technical delivery of VietinBank's core banking transformation — 155 branches, 8M+ customers — recognized as The Asian Banker's Best Core Banking Initiative, 2018 I hold an M.Tech in Data Science from BITS Pilani, which is mostly why I now spend as much time thinking about RAG pipelines and LLM evaluation as I do about Kafka topic design. People I've worked with tend to mention two things about me: I stay calm when a production integration is on fire, and I actually ship the "innovative idea" instead of just pitching it — four-time FIS Global Hackathon finalist, most recently in 2026 for an AI-driven release-validation platform. I'm an individual-contributor architect by choice. I'd rather go deep on a hard integration problem than manage a team's calendar — though I've mentored and indirectly led engineers throughout my career. If you're scaling banking, payments, or fintech platforms and need someone who can sit in a C-suite strategy conversation and then review the API contract an hour later, let's talk. 📩 Vivek.Tandon@gmail.com
