On-Device AI: When Local Inference Changes Product Architecture
The standard SaaS architecture for AI routes every single keystroke, search query, and autocomplete request over the public internet to hyperscaler cloud APIs. This creates linear compute bills ($0.01–$0.05 per request), introduces 800ms network round-trip latency, and violates strict data residency laws. Learn how client-side WebGPU, Apple MLX, and quantized 1B–3B small language models enable sub-10ms latency, offline-first product functionality, and infinite margin scaling.
Small Models vs Cloud Models: Designing Hybrid AI Systems
The naive pattern in enterprise AI is routing 100% of user traffic to a monolithic cloud frontier model (like GPT-4o or Claude 3.5 Sonnet). This results in massive cloud compute bills, slow 1.2s P95 latencies, and unnecessary data transfer. Discover how hybrid routing systems dispatch 85%+ of routine classification, entity extraction, and syntax normalization tasks to sub-30ms Small Language Models (SLMs 1B–8B), routing only high-complexity multi-step reasoning to cloud LLMs.
Computer Vision Pipelines Beyond the Model
In academic computer vision papers, success is defined solely by mAP accuracy scores on static benchmark images. In industrial production (manufacturing factories, automated tollways, and autonomous retail), model inference represents barely 10% of the engineering effort. The real challenges are hardware RTSP stream decimation, multi-object tracking stability across camera occlusions, TensorRT edge compilation, and real-time MQTT telemetry dispatch. Learn how to architect end-to-end edge CV pipelines.
Human Review Queues for Computer Vision Systems
The naive goal of computer vision is 100% full automation. In high-stakes manufacturing, medical imaging, and security screening, relying on fully autonomous model decisions creates catastrophic failure modes: false negatives ship defective products to customers, while false positives repeatedly halt multi-million-dollar assembly lines. Learn how to architect ergonomic human review queues where operators verify low-confidence detections in sub-second bursts with single-keystroke triage.
Offline and Edge AI: Product Design Under Connectivity Constraints
Most AI software assumes an uninterrupted 5G broadband connection. However, critical enterprise workers—such as offshore oil rig technicians, mining engineers, aviation maintenance crews, and disaster relief teams—operate in environments with intermittent, high-latency, or zero internet access. Learn how to architect true local-first, offline AI applications using embedded SQLite vector databases, on-device small models, and Conflict-Free Replicated Data Types (CRDTs).
Platform Engineering in the Age of AI Agents
Platform engineering teams spent the last decade building Internal Developer Platforms (IDPs) optimized for human workflows: Backstage service catalogs, Slackbot approvals, and Jira ticket automation. In the era of autonomous AI agents, platform teams face a radical transformation: the primary consumer of infrastructure APIs is now a synthetic coding agent that provisions environments, tests pull requests, and queries databases in sub-second bursts. Learn how to architect agent-ready platform control planes.
Designing Internal Developer Platforms That Developers Actually Use
The graveyard of enterprise software is littered with abandoned Internal Developer Platforms (IDPs). Platform teams spend millions building complex Backstage portals with fifty mandatory form fields, only to watch developers bypass the platform entirely and create shadow infrastructure via the AWS web console. Discover how to architect high-adoption Golden Paths: self-service CLI templates, automatic environment provisioning, and pre-wired observability that engineers genuinely love.
Cloud FinOps for AI Workloads
In traditional cloud computing, over-provisioned EC2 instances cause a gradual 10% budget drift. In AI computing, unmonitored LLM token loops and idle reserved GPU clusters can run up a $50,000 cloud bill in a single weekend. Managing AI infrastructure costs requires a dedicated AI FinOps discipline: real-time token attribution per customer tenant, aggressive prompt caching architectures, GPU spot/reserved instance optimization, and automated model tier step-down policies.
Observability for Modern Distributed Applications
When an application consisted of a single monolith and a PostgreSQL database, debugging an issue was simple: SSH into the server and grep the log file. In a modern distributed architecture with fifty microservices, asynchronous queues, and autonomous AI agents, a single user click spans dozens of network hops. Siloed logs and disconnected dashboards turn incidents into four-hour triage nightmares. Learn how to architect end-to-end OpenTelemetry distributed tracing and eBPF kernel monitoring.
Designing API Platforms for Humans and AI Agents
For twenty years, API platforms were built for a single audience: human software engineers reading HTML documentation, copy-pasting cURL snippets, and clicking 'Try It Out' buttons in Swagger UI. In the agentic era, more than half of API calls originate from autonomous AI agents that parse schemas, construct payloads, and execute multi-step workflows without human eyes. Discover how to build a unified API platform that serves human developers with beautiful portals while exposing strict OpenAPI 3.1 and Model Context Protocol (MCP) servers for synthetic agents.
