Describe Your Primary Tech Stack, Rationale, and Scale

Context: In a software-engineering HR screen, briefly summarize your core technology stack and where you have used it in production.

Please cover:

  1. Languages
  2. Frameworks and runtimes (backend, frontend, data/ML)
  3. Services and messaging (e.g., queues/streams, APIs)
  4. Data stores (OLTP, caches, analytics/lake)
  5. Infrastructure and DevOps (cloud, orchestration, IaC, CI/CD, observability)

Also address:

  • Why you chose these technologies (performance, reliability, developer productivity, security/compliance, cost).
  • The scale and performance you have handled (throughput/RPS, latency percentiles, data volume, concurrency, uptime/SLOs, regions).
