Frontier Systems

Build the distributed, real-time substrate AI runs on.

Engineer the systems frontier AI depends on: large-scale distributed training, real-time and streaming AI, GPU cluster scheduling, vector databases at scale, and the consistency and fault-tolerance tradeoffs underneath it all. You leave able to reason about and operate planet-scale AI infrastructure. Bridges to Distributed Systems, Databases, and Operating Systems.

Week by week

Twelve weeks, fully mapped.

Every week unlocks the next. Concepts route you to free, world-class material; projects turn that knowledge into something deployed.

Week 1

Week 3

Consensus & Coordination

How distributed components agree under failure: Raft, leader election, replicated logs, and the coordination primitives that GPU schedulers and metadata stores depend on.

Bridges to Distributed Systems — consensus, replication, and fault tolerance

Builds on: Distributed Systems Foundations

Week 4

Distributed Training & Parallelism

Train a model too big for one GPU: data, tensor, pipeline, and fully-sharded parallelism, plus the collective communication (all-reduce) that makes them work.

Bridges to Parallel Computing — collective communication and parallel decomposition

Builds on: Consensus & Coordination

Week 6

GPU Cluster Scheduling

Pack expensive accelerators efficiently: gang scheduling, fairness, preemption, topology-aware placement, and the scheduling tradeoffs that decide cluster utilization.

Bridges to Operating Systems — scheduling, resource allocation, and fairness

Builds on: Distributed Training & Parallelism

Week 7

Real-Time & Streaming AI Systems

Process events as they arrive: streaming logs, exactly-once semantics, windowing, backpressure, and serving low-latency inference on a live data stream.

Builds on: GPU Cluster Scheduling

Week 8

Distributed Training System for a Multi-GPU Model

Week 8 milestone

An enterprise mandate: train a model that does not fit on one GPU, and turn the result into a launched product. Build a distributed training setup that uses data and at least one model-parallel strategy (tensor, pipeline, or fully-sharded), with correct collective communication, checkpointing that survives a node failure, and a throughput report. The run will be long; it must resume cleanly from a checkpoint after a simulated crash. The deliverable is not just training logs — the resulting model must be served as a directly deployable, hyperscalable product: a real public API with a hyper-usable demo UI, autoscaling, CI/CD, observability, security, and a live training-metrics dashboard. It ships complete with marketing — a landing page, a pitch, and a demo. We are not here to babysit a job that loses days of compute on one failure; ship the model as a real product.

Why it matters: Distributed training is the backbone skill behind every frontier model, and few engineers can debug a stalled all-reduce or a corrupt checkpoint. A builder who ships a fault-tolerant multi-GPU training system is directly deployable as a Distributed Systems or Training Infrastructure Engineer, one of the scarcest and highest-paid frontier roles, well into ₹1-crore-tier compensation.

The deliverable

A public repo, a benchmark report, and a publicly hosted product with a stable URL and a hyper-usable demo UI serving the trained model: the distributed training configuration, the parallelism strategy, the checkpoint-and-resume logic, a live training-metrics dashboard, an autoscaling serving deployment, CI/CD on every commit, production observability, a scaling report across GPU counts, a marketing landing page, a 10-slide pitch, a recorded demo, and a README documenting the communication pattern, the failure-recovery design, and the serving-scale design.

What it ships
  • A job launcher that takes a model and dataset and spreads training across multiple GPUs from a simple config.
  • Data parallelism plus at least one model-parallel strategy (tensor, pipeline, or fully-sharded).
  • Gang scheduling so every worker in a job starts together, preventing partial scheduling that idles GPUs.
  • Periodic distributed checkpointing with clean resume after a simulated node failure, losing no completed steps.
  • A live training dashboard: loss curves, throughput, GPU utilization, and inter-node communication overhead.
  • A scaling report that sweeps GPU counts and reports throughput and parallel efficiency.
  • Automatic detection and recovery from a stalled or crashed worker mid-run.
  • Spot/preemptible-instance support with checkpoint-driven recovery to cut training cost.
  • Serving of the trained model behind an OpenAI-compatible API with autoscaling.
  • A hyper-usable demo UI where a user can try the trained model on real prompts.
  • Production observability and a secured, rate-limited serving endpoint.

Market signal — who wants thisDistributed training infrastructure is a heavily funded 2026 category: Gartner projects $37.5B of end-user spending on AI-optimized infrastructure in 2026, and a market of training-orchestration products has formed — CoreWeave's Kubernetes-native GPU cloud, dstack's distributed-training orchestration, NVIDIA's open-source KAI Scheduler with gang scheduling, and NVIDIA Run:ai. Investors fund training infrastructure that keeps expensive clusters above 70% utilization; the scarce, decisive skill is making multi-GPU jobs fault-tolerant and efficient, not merely launching them.

How it is graded
  • Training runs across multiple GPUs using data plus at least one model-parallel strategy, with correct collective communication and the parallelism decomposition documented.
  • Checkpointing is implemented and the run resumes correctly after a simulated node failure.
  • A scaling report shows throughput and efficiency across GPU counts, and communication-versus-computation overhead is measured and discussed.
  • The trained model is served as a directly deployable product behind a real public API with a hyper-usable demo UI, autoscaling, CI/CD on every commit, observability, and a secured endpoint.
  • A live training-metrics dashboard is provided, and the serving layer holds under concurrent load.
  • The project ships complete marketing — a landing page, a 10-slide pitch, and a recorded demo.
  • The repo is reproducible with a clear benchmark methodology and the product is publicly reachable.

Vector Databases at Scale

Index and serve billions of embeddings: HNSW and IVF indexes, sharding, quantization for storage, and the recall-latency-cost surface of large-scale similarity search.

Bridges to Databases — indexing, sharding, and query optimization

Builds on: Real-Time & Streaming AI Systems

Week 11

Fault Tolerance & Resilient Operations

Build systems that survive failure: checkpointing long training runs, circuit breakers, retries with backoff and jitter, graceful degradation, and SLO-driven operations.

Week 12

Cluster Observability & Capacity Planning

Operate a fleet you can see: metrics, traces, and logs across nodes; SLOs and error budgets; and capacity planning so an AI cluster neither starves nor burns money idle.

Real-Time Streaming AI Inference Platform

Week 12 milestone

An enterprise mandate: build and launch a platform that consumes a high-rate live event stream, runs inference on each event with low latency, indexes results into a vector store, and serves real-time similarity queries — all while staying healthy under bursty load and a node failure. This is a distributed-systems problem with AI inside it: exactly-once or well-reasoned delivery semantics, backpressure, autoscaling, GPU-aware scheduling, and observability across the fleet. The deliverable is a directly deployable, hyperscalable product: real public hosting, CI/CD, security, a hyper-usable real-time dashboard and query UI, and full marketing — a landing page, a pitch, and a demo. Deliver a platform that does not fall over when traffic spikes, that a buyer can evaluate, and that is presentable as a real product. Ship it as a real product.

Why it matters: Real-time AI on live data powers fraud detection, recommendations, and observability products across every major platform. A builder who ships a streaming inference platform that holds up under load and failure is directly deployable as a senior Distributed Systems or Real-Time AI Engineer, a ₹1-crore-tier role because it demands both systems depth and AI fluency.

The deliverable

A publicly hosted platform with a stable URL and a hyper-usable real-time dashboard plus query UI, plus a public repo: the streaming ingestion and inference pipeline, the at-scale vector index, the autoscaling and backpressure design, CI/CD on every commit, fleet observability, a load-and-failure test report, a marketing landing page, a 10-slide pitch, a recorded demo, and a README documenting delivery semantics, fault tolerance, security, and capacity planning.

What it ships
  • Ingestion of a high-rate live event stream (transactions, clicks, logs) from a streaming log such as Kafka.
  • Per-event low-latency inference with a documented end-to-end latency budget (target sub-100ms).
  • Stated delivery semantics — exactly-once, or at-least-once with idempotent processing — enforced in the pipeline.
  • A feature layer that assembles per-event features within the latency window for the model.
  • Inference results indexed into a vector store serving real-time similarity and nearest-neighbor queries.
  • Backpressure and autoscaling that keep the platform healthy through a sudden traffic burst.
  • Node-failure recovery with graceful degradation, demonstrated via injected failure.
  • A real-time dashboard of event throughput, inference latency percentiles, and fleet health.
  • A query UI for similarity search and recent-event lookup, usable without instruction.
  • Alerting on latency-SLO breaches, lag buildup, and anomalous event rates.
  • Multi-tenant isolation and a secured, rate-limited query API.

Market signal — who wants thisReal-time streaming AI is a funded 2026 category anchored in fraud detection and live personalization: Artie raised a $12M Series A to make real-time data the default for AI systems, Experian launched real-time AI fraud detection with Resistant AI's 80+ models, and global fintech venture funding hit $12B across 751 deals by April 2026. Production fraud models need sub-millisecond feature retrieval and 20-100+ features within a 100ms window, served by vector databases like Pinecone, Milvus, and Redis. Investors fund streaming-AI platforms because regulated finance and large consumer platforms must score live events instantly or lose money.

How it is graded
  • A live event stream is consumed and inference runs per event with measured low latency.
  • Delivery semantics (exactly-once or at-least-once with idempotency) are stated and justified.
  • Inference results are indexed into a vector store that serves real-time similarity queries.
  • Backpressure and autoscaling keep the platform healthy under a simulated traffic burst, and an injected node failure is recovered with graceful degradation.
  • The platform is deployed to real public hosting with CI/CD on every commit, fleet observability, and security hardening.
  • A fast, WCAG 2.2 AA accessible real-time dashboard and query UI lets a stranger use the platform without instruction.
  • The project ships complete marketing — a landing page, a 10-slide pitch, and a recorded demo.
  • The platform is publicly reachable and fully reproducible from the repo.
