Full StackWhy we replaced REST with tRPC for cohort dashboards
Six months ago we ripped out 14 REST endpoints. Here's the type-safety dividend, the cold-start gotcha, and the migration plan that didn't break a single learner login.
Engineering tutorials, placement playbooks, and lessons from running 200+ cohorts. Written by working engineers — no fluff, no SEO bait.

Data ScienceIf you can grok dot products, you can grok embeddings. Build a movie-recommender from scratch in 60 lines — no PyTorch, no TensorFlow, no jargon.
PlacementsWe surveyed our recruiter network. The result is uncomfortable: most learners spend their portfolio time on the wrong things. Here's what to swap in.
EngineeringMost senior-level system-design interviews don't require Kafka, Redis Streams, or Cassandra. Two well-shaped Postgres tables get you 80% of the way there.
CareerAfter reviewing 5,000+ resumes from our cohorts, the pattern is clear. Most candidates are fighting their template. Here is the layout that wins consistently.
AI toolingPractical patterns we use in production to keep LLM costs under 4% of revenue: caching, model routing, evals, and the one habit nobody talks about.
