The Simplico Engineering Library: A Field Guide to Production Software, AI, and Security in 2026

Most engineering blogs are written for an audience that already exists. This one is written for the engineer, founder, or operations leader who is about to deal with a problem — and is trying to find someone who has actually shipped a working system, not just summarized a vendor whitepaper.

Over the past months we have published more than fifty deep technical posts on simplico.net, covering production AI, RAG, security operations, manufacturing systems, ERP, ecommerce infrastructure, and the legal and operational realities of running real software for businesses across Thailand, Japan, China, and the EU. This page exists so you do not have to scroll through the chronological feed to find what is relevant to you.

The articles are grouped by problem, not by date. Each section is a place a real customer has come to us with a real budget and a real deadline. Pick the one that matches what you are actually trying to do.

1. Production AI and Agentic Systems — what works when the demo ends

Most AI content stops at "look how impressive this prototype is." The hard part starts the day you have to put it in front of paying customers, with audit logs, error handling, and a CFO asking what it costs.

Building a Tier-1 SOC Analyst Agent: Wazuh + Claude + Shuffle in Production — the flagship piece on agentic security operations. Why most "AI for SOC" pitches do not work, and the architecture pattern that does. Available in TH · JA · ZH
Agentic AI in SOC Workflows: Beyond Playbooks into Autonomous Defense — the conceptual companion: what changes when your security automation can reason, not just follow scripts. Also in TH · JA
Why Your RAG App Fails in Production — the failure modes that only show up at scale, and why the "chunk and embed" tutorials do not survive contact with real users. Also in TH · JA · ZH
LlamaIndex + pgvector: Production RAG for Thai and Japanese Business Documents — the multilingual RAG architecture that actually handles CJK and Thai script properly, with concrete pgvector tuning. Also in TH · JA
The Price of Intelligence: What AI Really Costs — token economics for production deployments, written for the CFO who needs a real number. Also in TH

AI Security in Production: What Enterprise Teams Must Know in 2026 — prompt injection, model exfiltration, and the threats that do not exist in your current security stack.

If you are just starting to plan an AI deployment, the SOC piece is the most concrete starting point. If you are already in production and something is broken, the RAG failures piece is probably what you came for.

2. ESG, CSRD, and the Compliance Engineering Stack

The European Union’s CSRD regime turned sustainability reporting from a marketing exercise into a regulated, audited financial filing. For Asian conglomerates with EU subsidiaries, this is the largest forced-spend software opportunity of the decade — and the integration layer is where most of the budget and most of the failure happens.

The ESG Data Bridge: Why CSRD Implementation Costs Most in the Layer No One Discusses — the flagship analysis. Why your reporting tool’s connectors do not actually solve the data problem, and what the missing layer is. Also in TH · JA · ZH
What’s Actually Inside a €3M Big 4 CSRD Quote — A Line-by-Line Breakdown — the buyer’s playbook. Where the money goes in a Big 4 readiness proposal, what is fat, and what to push back on. Also in TH · JA · ZH
Reading Asian Utility Bills at Audit Quality: How simpliDoc Handles the PDF Problem in CSRD — the technical deep dive. Why generic OCR fails on Japanese and Chinese utility bills, and what an audit-grade document AI pipeline actually looks like. Also in TH · JA

If you are scoping CSRD readiness right now, read these in order. The flagship sets the strategic frame, the Big 4 piece arms you for procurement, and the simpliDoc piece tells your IT team what actually has to be built.

3. Security Operations and SOC Engineering

Security operations is where Simplico has shipped the most production code. Open-source-anchored, audit-defensible, and priced honestly against the SIer-dominated alternatives.

Building a SOC from Scratch: A Real-World Wazuh + IRIS-Web Field Report — the operational walkthrough. What the first six months of running a real SOC actually looks like. Also in TH · JA · ZH
How We Built a Real Security Operations Center with Open Source Tools — the architecture and stack choices, with concrete tradeoffs. Also in TH · JA · ZH

Wazuh Decoders & Rules: The Missing Mental Model — the technical piece that explains why most Wazuh deployments quietly fail at detection. Also in TH · JA · ZH
AI-Powered Network Security Monitoring (NSM) — what actually changes when you put an LLM in the loop on network telemetry. Also in TH · JA · ZH
NSM vs AV vs IPS vs IDS vs EDR: What Your Security Architecture Is Probably Missing — the buyer’s-eye view of an industry full of acronyms. Also in TH · JA · ZH
Critical Infrastructure Under Fire: Lessons from Ukraine’s Energy Grid — what IT and OT security teams should actually take from a real-world conflict. Also in TH · JA · ZH

For a CISO reading top-down, the SOC field report is the place to start. For a security engineer building the thing, the Wazuh decoders piece is the most useful single article we have published.

4. ERP, Manufacturing, and Industrial Software

The reality of mid-market manufacturing in Asia: factory ERPs nobody has heard of in Frankfurt, shop-floor PLCs older than most of the engineers maintaining them, and tier-2 suppliers being squeezed by their FDI customers to digitize on a budget that does not exist.

Why ERP Projects Fail (and How to Make Yours Succeed) — the structural reasons ERP projects collapse, and what the survivors do differently. Also in TH · JA · ZH

The $1M Enterprise Software Myth — when the open-source-plus-AI alternative actually beats the seven-figure platform, and when it does not. Also in TH
Software for Recycling Factories in Thailand — vertical-specific factory operations software (Thai-only article). Also in JA · ZH
Why Your Finance Team Spends 40% of Their Week on Work AI Can Now Do — the finance-back-office automation argument, with specifics. Also in TH
The Accounting Software Your Firm Uses Is Built for Your Clients, Not for You — for accounting practices specifically, why most stack choices are backwards. Also in TH

If you have an ERP project that is not going well, start with the Why ERP Projects Fail piece. If you are scoping a new one, the OEE article is the best starting point for getting the technical foundation right.

5. Ecommerce, Payments, and Retail Infrastructure

The unglamorous infrastructure under every online business — caching, payment idempotency, ERP integration, multi-language storefronts — is where projects quietly bleed money.

How to Connect Your Ecommerce Store to Your ERP — A Practical Guide for 2026 — the integration patterns that actually survive a Black Friday spike. Also in TH · JA · ZH
Idempotency in Payment APIs: Prevent Double Charges with Stripe, Omise, and 2C2P — the failure mode that ruins payment trust, and the boring engineering that prevents it. Also in TH · JA · ZH

simpliShop: The Thai Ecommerce Platform for Made-to-Order and Multi-Language Stores — Simplico’s own ecommerce product. Also in TH · JA · ZH

The idempotency post is the one we send most often when a customer tells us they have payment-reconciliation problems. It is also the cheapest engineering investment that prevents a class of issues that scale with revenue.

6. AI Coding Tools, Local LLMs, and the Engineer’s Stack

For software engineers and the leaders who manage them: how AI changes the actual day-to-day of writing software, and the practical infrastructure for running models without sending everything to OpenAI.

7. EV Charging, Smart Energy, and OCPP

Charging operators emerging from utilities, gas-station chains, and industrial estate operators face the same software gap: OCPP-compliant CSMS, white-label apps, and integration into local payment rails.

8. Vertical Industry Software — Agriculture, Recycling, Specialized Operations

Niche vertical software is where Simplico has shipped some of its most distinctive work — the kind that requires walking a Thai durian depot or a Chinese recycling facility, not a webinar.

The Modern Durian Depot: Stop Counting Stock on Paper, Start Running a Real Business — vertical software for the Thai durian export trade. Also in TH · JA · ZH
Durian Fruit Depot Management Software: WMS, ERP Integration, Export Automation — the technical details, for the IT side of the same buyer. Also in TH · JA · ZH

9. Engineering as Craft — Cars, Driving, and the Side Topics

Not all of our writing is about software. Some of the most-read pieces are about the engineering of physical things — and engineers’ eyes light up at them more than at the corporate content.

How to Improve Fuel Economy: The Physics of High-Load Low-RPM Driving — what BSFC charts actually mean for daily driving. Also in TH · JA

How to use this library

If you arrived here from a search, the article you searched for is in one of the sections above. Find it, read it, and if it answers your question that is the goal of this page.

If you arrived here from somewhere else and you are not sure where to start, three honest recommendations:

If you are an engineer, read the Wazuh Decoders & Rules post and the NumPy Broadcasting post first. They are both about the difference between code that looks correct and code that is correct, which is the whole job.

If you are a CTO or engineering leader, read the ESG Data Bridge flagship and the Why ERP Projects Fail post. They are about how to think about large software investments where the cost of being wrong is much higher than the cost of being slow.

If you are a CFO, the Big 4 CSRD Quote Breakdown is the single piece on this site most likely to save you a six-figure sum in your next procurement cycle.

If none of those fit, scroll back up and pick the section that matches what you are working on. Every link goes to a real article written by people who have actually shipped the system being described.

If you are working on something where one of these articles is close to what you need but not quite — or where you have read three of them and want to talk to the authors directly about your specific situation — that is exactly what we do at Simplico. The article comments are slow; the contact form is fast. We respond personally, usually within one business day, in English, Thai, Japanese, or Chinese as you prefer.
