Typestate: Encoding Protocols in Types
Typestate turns protocol states and legal transitions into APIs that reject invalid operation sequences before execution.
Building Reliable LLM Applications
Engineer LLM systems with typed outputs, grounded evidence, controlled tools, evals, observability, canaries, and incident-ready fallbacks.
Binary Search on the Answer: Turning Feasibility into Optimization
Solve optimization problems by proving a monotone feasibility predicate and preserving explicit search-boundary invariants.
Multimodal AI Systems: Text, Images, and Structured Data
Design multimodal systems around explicit modality contracts, evidence-preserving fusion, bounded tools, privacy, fallbacks, and end-to-end verification.
Authorization Models: RBAC, ABAC, and ReBAC
Compare RBAC, ABAC, and ReBAC by how they express policy, preserve tenant boundaries, support revocation, and produce testable decisions.
Service Discovery and Health Checking
Design service discovery as a converging membership system with explicit readiness, liveness, staleness, and observability contracts.
Normalization and Denormalization by Invariant
Design normalized sources of truth and deliberate denormalized projections by assigning every business invariant a clear owner.
How CSS Layout Resolves Flexbox and Grid
Reason about Flexbox and Grid through intrinsic sizes, free-space distribution, track sizing, overflow constraints, and reproducible debugging.
Serverless Architecture: A Decision Framework
Choose serverless by matching workload shape, event semantics, state, platform limits, cost curves, and operating responsibilities to explicit requirements.
Cache Locality and Data-Oriented Design
Reshape hot data and traversal around actual access patterns so each fetched cache line performs useful work without sacrificing honest measurement or maintainability.
Filesystems: Page Caches, Journals, and Durable Writes
Trace a write from the page cache through journaling and storage, then build crash-safe file replacement from explicit guarantees.
Work-Stealing Schedulers for Parallel Tasks
Understand how per-worker deques, selective stealing, task granularity, and runtime telemetry turn irregular parallel work into balanced execution.
