Xiaojia,

Happy New Year! I saw your post about hiring L4 Backend Engineers for the Payment and Business Integrity teams at Snap. Building mission-critical large-scale services and driving Gen AI adoption is exactly the kind of challenge I'm looking for.

What I Bring:

Backend Services & Distributed Systems:

- Built ReachAI: scalable backend service with microservices architecture handling concurrent requests

- Memory-as-a-Service: high-availability API with sub-50ms latency, Redis caching, PostgreSQL

- Experience with Python, FastAPI, REST APIs, and system design

Operational Excellence:

- Operated MailAlarm 24/7 with monitoring, incident handling, and hotfix resolution

- I understand the operational aspects of systems and can participate in incident investigation

Generative AI:

- Integrated LangChain and Groq into production systems (LLMResume serves 500+ users)

- Excited to drive Gen AI adoption to tackle challenging problems

Scalability:

- Built systems designed for high availability and scale

- Experience with Docker, cloud infrastructure, and database optimization

I'm ready to work on exciting product initiatives and collaborate with talented engineers. Looking forward to the opportunity to work together!

Best,

Rikin Shah
