🎯 Who is this job for?

This role is suitable for a Senior full-stack software engineer with 5+ years of professional experience designing and leading complex, scalable features.

Required skills include strong Node.js or Go, React with TypeScript, gRPC and REST APIs, microservices, PostgreSQL and SQL optimization, Redis, AWS, Docker, Terraform, and high-performance distributed systems.

The candidate should be familiar with building real-time backend services, data-rich dashboards, asynchronous workers, AI integrations, analytics workloads, infrastructure, automated tests, architecture discussions, code reviews, mentoring, and cross-team collaboration.

💬 Potential Interview Questions

How would you design a scalable Node.js or Go service for real-time campus movement workflows?

I would separate ingestion, processing, and delivery concerns using stateless services, asynchronous queues, and well-defined APIs. I would use concurrency controls, idempotent event handling, horizontal scaling, and observability to support high throughput and reliable real-time updates.

When would you choose gRPC over REST for service-to-service communication?

gRPC is appropriate for internal services that need efficient, strongly typed, low-latency communication and streaming capabilities. REST is often preferable for public APIs, browser-facing integrations, and scenarios where broad interoperability and human-readable requests are important.

How would you optimize a slow PostgreSQL query used for analytics?

I would inspect the execution plan with EXPLAIN ANALYZE, verify index usage, and review joins, filtering, sorting, and aggregation costs. Depending on the workload, I might add or adjust indexes, partition large tables, rewrite the query, pre-aggregate data, or move heavy analytical processing to services such as Athena.

How would you design background workers for reliable asynchronous data processing?

I would use a durable queue such as SQS, make jobs idempotent, and implement visibility timeouts, retries with exponential backoff, and a dead-letter queue. Workers should expose metrics for throughput, latency, failures, and backlog so the system can be scaled and operated safely.

What caching strategy would you use with Redis for a high-traffic application?

I would cache stable or expensive-to-compute data with explicit TTLs and use cache-aside behavior where appropriate. I would define invalidation rules, protect against cache stampedes, monitor hit rates, and use Redis Cluster or multi-tier caching when capacity and availability requirements demand it.

How would you build a performant React and TypeScript dashboard containing large amounts of data?

I would use strongly typed data contracts, server-side pagination or aggregation, and query caching to avoid unnecessary requests. I would also apply memoization selectively, virtualize large lists, lazy-load routes and components, and use efficient visualization techniques to keep rendering responsive.

How would you ensure consistency between a React frontend and gRPC or REST backend APIs?

I would establish versioned contracts and generate or share TypeScript types where possible, while validating inputs and responses at runtime. Automated contract tests, backward-compatible changes, and clear error models help prevent frontend and backend drift.

How would you integrate an LLM feature such as generative reporting into a production application?

I would isolate the LLM integration behind a service that handles prompt construction, authorization, rate limits, retries, timeouts, and provider failures. I would validate and sanitize inputs, protect sensitive student data, evaluate output quality, and include human review or confidence indicators for consequential results.

How would you deploy and manage AWS infrastructure for these services using Terraform?

I would create reusable Terraform modules for networking, ECS or Kubernetes workloads, databases, queues, storage, and IAM, with remote state locking and environment-specific configuration. Changes should be reviewed through CI, plan outputs, policy checks, and controlled deployments with least-privilege access.

How would you diagnose a production performance regression across a full-stack system?

I would use correlated logs, metrics, traces, and deployment history to identify whether the issue is in the browser, API, database, queue, or infrastructure. I would reproduce the bottleneck with representative load, mitigate customer impact first, then implement and verify a permanent fix with regression tests and monitoring.
