Pros
Worked on large-scale, real-world fintech systems handling high-throughput payment flows • Gained deep exposure to backend engineering, including transaction processing, messaging protocols, and system integrations • Opportunity to work with experienced engineers and learn industry-standard practices • Good environment to understand reliability, correctness, and performance constraints in production systems • Helpful for building a strong foundation in system-level thinking and debugging
Cons
Legacy codebases and systems can slow development and onboarding • Engineering processes and tooling feel dated in some teams • Limited exposure to modern tech stacks and cloud-native architectures • Growth and learning can depend heavily on team and project assignment • Pace of change can feel slow in a large, established organization
