They are terrible at finding out why something broke. That is a discipline problem — and manufacturing solved it sixty years ago. engineering ai-agents debugging root-cause-analysis software-engineering https://hrushiekeshreddykanjula.com/blog/context-window-tokenization-skills-cost https://hrushiekeshreddykanjula.com/blog/context-window-tokenization-skills-cost Tue, 26 May 2026 00:00:00 GMT Every skill you load, every message you send, every document you attach quietly eats into the same fixed budget. Here's what happens when that budget runs out — and how to spend it wisely. ai context-window tokenization cost-optimization skills productivity developer-tools https://hrushiekeshreddykanjula.com/blog/parallel-ai-agents-file-locking https://hrushiekeshreddykanjula.com/blog/parallel-ai-agents-file-locking Mon, 25 May 2026 00:00:00 GMT Two AI agents writing to the same file simultaneously is a data corruption event. Here is the file-locking orchestration layer that makes parallel AI development safe and fast. ai multi-agent engineering architecture langgraph parallel-execution https://hrushiekeshreddykanjula.com/blog/multi-agent-ai-governance-manufacturing https://hrushiekeshreddykanjula.com/blog/multi-agent-ai-governance-manufacturing Mon, 18 May 2026 00:00:00 GMT Giving an LLM access to your codebase without governance constraints is like hiring a contractor and handing them the master key on day one. Here is the governance framework that keeps multi-agent AI development safe and productive. ai multi-agent llm governance engineering architecture https://hrushiekeshreddykanjula.com/blog/ai-literacy-prompt-vs-architecture-engineering https://hrushiekeshreddykanjula.com/blog/ai-literacy-prompt-vs-architecture-engineering Mon, 11 May 2026 00:00:00 GMT The highest-leverage AI skill in 2026 is not writing better prompts. It is knowing which problems need a prompt and which need a full architectural design. Here is the line I draw. ai engineering architecture llm productivity essay https://hrushiekeshreddykanjula.com/blog/rotation-heuristics-ipc2581-smt https://hrushiekeshreddykanjula.com/blog/rotation-heuristics-ipc2581-smt Mon, 04 May 2026 00:00:00 GMT A 180-degree rotation error on a polarized capacitor causes a short circuit. A three-tier heuristic system catches most of them. The IPC-2581 standard would make the whole problem obsolete. smt manufacturing python ipc-2581 heuristics pcb https://hrushiekeshreddykanjula.com/blog/smt-nozzle-physics-validation-asyncio https://hrushiekeshreddykanjula.com/blog/smt-nozzle-physics-validation-asyncio Mon, 27 Apr 2026 00:00:00 GMT Every component on a PCB has a physical body width. Every nozzle has an outer diameter. If the nozzle is too large, it drops the part. Here is the 1,600-line async pipeline that validates this at scale. python asyncio manufacturing smt physics validation https://hrushiekeshreddykanjula.com/blog/cross-linking-inspection-production-telemetry https://hrushiekeshreddykanjula.com/blog/cross-linking-inspection-production-telemetry Mon, 20 Apr 2026 00:00:00 GMT An optical defect and the machine event that caused it happen minutes apart and live in separate databases. Time-windowing SQL joins close the loop — here is how. sql manufacturing analytics aoi smt data-engineering https://hrushiekeshreddykanjula.com/blog/sql-window-functions-data-interpolation https://hrushiekeshreddykanjula.com/blog/sql-window-functions-data-interpolation Mon, 13 Apr 2026 00:00:00 GMT SMT machines log generic errors milliseconds before they log the component that caused them. A forward-fill CTE using SQL window functions bridges that gap — here is exactly how it works. sql sqlite window-functions manufacturing data-engineering analytics https://hrushiekeshreddykanjula.com/blog/time-series-analytics-hardware-degradation https://hrushiekeshreddykanjula.com/blog/time-series-analytics-hardware-degradation Mon, 06 Apr 2026 00:00:00 GMT Raw machine telemetry tells you what happened. Time-series analytics tells you what is about to happen. Here is how First-Pass Yield, rolling defect rates, and SQL-driven root cause analysis work together. python sql time-series analytics manufacturing predictive-maintenance https://hrushiekeshreddykanjula.com/blog/xml-telemetry-relational-database-fpt https://hrushiekeshreddykanjula.com/blog/xml-telemetry-relational-database-fpt Mon, 30 Mar 2026 00:00:00 GMT Flying Probe Tester XML files are massive, nested, and namespace-unstable. Here is the three-table relational schema and defensive parsing strategy that tames them. python xml sqlite manufacturing testing data-engineering https://hrushiekeshreddykanjula.com/blog/fuzzy-matching-aoi-inspection-telemetry https://hrushiekeshreddykanjula.com/blog/fuzzy-matching-aoi-inspection-telemetry Mon, 23 Mar 2026 00:00:00 GMT AOI machines generate defect reports with part numbers that almost match your library. Here is the dynamic parsing and fuzzy matching system that bridges that gap. python fuzzy-matching aoi manufacturing inspection data-engineering https://hrushiekeshreddykanjula.com/blog/adaptive-bom-ingestion-stochastic-files https://hrushiekeshreddykanjula.com/blog/adaptive-bom-ingestion-stochastic-files Mon, 16 Mar 2026 00:00:00 GMT Customers send spreadsheets that look nothing alike. Hardcoded column indices fail on day two. Here is the four-step heuristic pipeline that handles anything. python data-engineering excel bom heuristics manufacturing https://hrushiekeshreddykanjula.com/blog/bom-normalization-manufacturing-scale https://hrushiekeshreddykanjula.com/blog/bom-normalization-manufacturing-scale Mon, 09 Mar 2026 00:00:00 GMT A 10kΩ resistor has at least eight names in the wild. Here is how a regex-driven normalization engine turns manufacturing chaos into a canonical data layer. python data-engineering manufacturing regex smt bom https://hrushiekeshreddykanjula.com/blog/python-state-management-async-ui https://hrushiekeshreddykanjula.com/blog/python-state-management-async-ui Mon, 02 Mar 2026 00:00:00 GMT When your Python backend and JavaScript frontend share state across async WebSocket calls, things fall apart fast. Here is the architecture that fixed it. python async state-management eel architecture manufacturing https://hrushiekeshreddykanjula.com/blog/eel-python-gui-edge-manufacturing https://hrushiekeshreddykanjula.com/blog/eel-python-gui-edge-manufacturing Mon, 23 Feb 2026 00:00:00 GMT PyQt was too limiting, Electron was too bloated. Eel let me build a glassmorphism dashboard on constrained edge hardware — and I almost feel bad about how well it worked. python eel electron gui edge-computing manufacturing https://hrushiekeshreddykanjula.com/blog/sqlite-wal-mode-edge-manufacturing https://hrushiekeshreddykanjula.com/blog/sqlite-wal-mode-edge-manufacturing Mon, 16 Feb 2026 00:00:00 GMT Everyone told me SQLite wasn't a real production database. Then I enabled WAL mode, handled concurrent MES workloads, and stopped worrying. sqlite python edge-computing database manufacturing concurrency https://hrushiekeshreddykanjula.com/blog/legacy-macros-to-full-stack-mes https://hrushiekeshreddykanjula.com/blog/legacy-macros-to-full-stack-mes Mon, 09 Feb 2026 00:00:00 GMT Every manufacturing team has that one Excel macro — the one nobody touches. Here's why I finally killed ours and what I built instead. python manufacturing full-stack smt mes vba https://hrushiekeshreddykanjula.com/blog/python-async-asyncio-aiohttp https://hrushiekeshreddykanjula.com/blog/python-async-asyncio-aiohttp Mon, 02 Feb 2026 00:00:00 GMT asyncio is not a magic speed-up — it's a precise tool for a specific problem. Here's what it actually does, when it wins, and when it costs you more than it's worth. python asyncio aiohttp concurrency engineering https://hrushiekeshreddykanjula.com/blog/agentic-workflow-claude-cursor-antigravity https://hrushiekeshreddykanjula.com/blog/agentic-workflow-claude-cursor-antigravity Mon, 26 Jan 2026 00:00:00 GMT I spent months running Claude Code, Cursor, and Google Antigravity 2.0 side-by-side on real projects. Here's what the combined agentic stack actually looks like — and where it breaks. claude-code cursor google-antigravity agentic-workflow engineering ai-tools https://hrushiekeshreddykanjula.com/blog/welcome https://hrushiekeshreddykanjula.com/blog/welcome Mon, 19 Jan 2026 10:00:00 GMT An intro to this space — what I'll be writing about, how the blog is generated, and what the assembly hub is. engineering portfolio claude-api
