Domain-driven platform engineering at scale in financial services | Fiserv, Visa & AvidXchange

Platform engineering in the banking, financial services, and insurance (BFSI) sector requires balancing standardization with business unit autonomy to reduce undifferentiated work. Successful implementation relies on creating "golden paths" that are compliant by default, effectively embedding security and regulatory guardrails directly into the developer workflow. While organizations face significant challenges with legacy systems and complex compliance requirements, shifting metrics from simple throughput to business outcomes and developer experience drives long-term success. The integration of AI and agentic delivery further necessitates robust platform foundations to ensure secure, auditable, and reliable deployments. Ultimately, the transition to platform engineering is a cultural shift that requires treating the platform as a product, prioritizing human-centric design, and fostering organizational alignment to overcome the friction of traditional, siloed development practices.
