Most candidates fail system design rounds because they've never been graded on one. This 60-minute mock is built for engineers targeting real infra and distributed systems companies — not generic product-co prep.

What we'll do:

• Real problem from the infra/data world — design a distributed SQL engine, a log-ingestion pipeline, a multi-tenant control plane, a real-time observability system, a vector DB, a CDC pipeline, a workflow orchestrator. Your pick or mine.

• 45 minutes of you driving the design — requirements, capacity, APIs, storage, consensus, sharding, replication, failure modes

• 15 minutes of structured feedback: where you nailed it, where an infra interviewer would push back, exactly what to fix

You'll get:

• A written scorecard graded the way infra teams actually grade (correctness, trade-offs, depth on storage/consistency/scaling)

• Specific concepts and papers to study based on gaps (Raft, MVCC, LSM trees, CRDTs, gossip, watermarking, etc.)

• A recording of the session (on request)

Why me: I work on distributed systems at SingleStore — zero-downtime deploys, multi-tenant model registry, real-time observability pipelines, fault-tolerant publishing — all running in production for 500+ enterprise customers. Before this I built LLM streaming + DAG orchestration at Convai.

Good for: engineers targeting database / streaming / cloud-infra / observability / dev-tools companies — SingleStore, Snowflake, Databricks, MongoDB, Yugabyte, Cockroach, Confluent, Cloudflare, Rubrik, Datadog, Stripe-infra, and similar.
