The Founder's Dilemma

Generalists are easy to find
Domain experts aren't

Shiftza finds engineers already building in your domain through open-source work.

no guess work, just real work

// the problem with hiring

Every candidate looks
great on paper.

AI resumes are indistinguishable. Anyone can write "built LLM systems" or "led AI initiatives." GitHub doesn't lie — the commits, stars, and repos are all there.

Looking for a senior backend engineer who has designed microservices, handled Kafka messaging, and built fault-tolerant distributed systems in production.

Great. To narrow down the best matches, I need to understand the tech stack. Are you looking for:

–Cloud native on AWS or GCP
–Container orchestration with Docker & Kubernetes
–SQL/NoSQL databases like PostgreSQL or MongoDB
–API design RESTful or GraphQL
AWS, Docker/Kubernetes, RESTful APIs, PostgreSQL + Redis. Kafka is must-have. Serverless is a plus.

Perfect. Here are the search queries I'll run — remove any that don't fit:

→ AWS cloud native microservices
→ Docker Kubernetes orchestration production
→ Kafka messaging system integration
→ RESTful API distributed systems
→ PostgreSQL Redis backend architecture
→ Serverless AWS Lambda deployment

Subject:Serverless platform role — aligned with your serverless repo

Hi Fengda,

I came across your phodal/serverless repo — your approach to serverless architecture with Serverless Framework and AWS Lambda + DynamoDB is exactly the kind of hands-on depth we're looking for.

At shiftza, we're building a distributed platform team and your background — 10k+ commits, TypeScript + Rust across 500+ repos — stands out.

Would you be open to a 20-minute call to hear more? No pressure — just happy to share what we're building.

Best,
Rishab sharma
