About Vamsi Krishna

I'm a backend engineer with 8 years in Python, mostly building multi-tenant SaaS and AI products. At Centific I designed an authentication platform that serves over 5 million users at 500+ TPS. These days I lead a pod at Turing, where I built simulated APIs that Google uses to train and evaluate LLM agents on tool calling, and I'm a core engineer on the event-driven ingestion platform behind a major US podcast network's catalog.

Outside client work I founded and still run southscape.tours, a tour booking SaaS for South India. I built everything myself, from payment gateway integrations to encrypted traveller data handling, and I operate it solo on Azure. That experience shapes how I work: I think about the product, not just the ticket, and I stay accountable for what I ship long after it goes live.

My core stack is Django, FastAPI, Celery, Kafka, PostgreSQL, Redis, Kubernetes, and Terraform on AWS and Azure.

    • • Core engineer on the distributed, event-driven ingestion platform powering the client's entire podcast catalog — a 21-package Python monorepo of pipeline workers, FastAPI services, and AWS Lambdas that detects RSS feed changes, ingests shows and episodes, and publishes updates downstream via Kafka.
    • • Led the ground-up migration of the catalog scan scheduler from a legacy Java Quartz system to a Python Celery/RedBeat architec ture: 5 coordinated services on AWS EKS with frequency-tiered scheduling (5-minute to weekly), priority-based RabbitMQ routing, distributed deduplication locking, and publish timeout/retry safeguards.
    • • Owned load testing and bottleneck analysis on a dedicated environment, tuning worker concurrency and queue roles to validate the new scheduler at production-scale catalog volumes and de-risk the cutover.
    • • Extended the pipeline end-to-end for video podcasts: RSS parsing, SQLAlchemy models with Alembic migrations, RabbitMQ mes sage schemas, and downstream Kafka contracts.
    • • Built Terraform-managed AWS Secrets Manager integration with GitHub Actions OIDC roles across dev and prod accounts, elimi nating long-lived credentials from CI/CD pipelines.
    • • Instrumented full observability for the scheduling system: Prometheus metrics, Grafana dashboards, New Relic APM, and struc tured logging shipped to Elasticsearch for cross-service failure tracing.

    • • Led development of simulated real-world service APIs used to train and evaluate LLM agents on production-style tool calling — strict tool specifications, stateful endpoint behavior, and schema-first Pydantic validation for deterministic, reliable execution.
    • • Partnered directly with Google stakeholders on requirements, led peer reviews, and strengthened Pytest regression coverage across the platform (team of 6).
