SaaS Payments from Turkey: Stripe Alternatives and Real Costs
Stripe and PayPal don't work in Turkey. Real cost breakdown of Paddle, iyzico, Polar.sh and PayTR for selling SaaS, MoR vs local virtual POS tradeoffs and tax advantages.
Multi-Layer Defense for LLM Production Systems: From Layer 0 to Human-in-the-Loop
Effective defense against LLM failure modes cannot be single-layered. Mode-by-mode matrix and implementation patterns for prompt, output validation, agent guardrails, observability, and human-in-the-loop layers.
LLM Agentic Failure Modes: Task Drift, Reward Hacking, Alignment Faking and More
Eight LLM failure modes that surface only in agent and tool-use systems. Mechanism and defense for task drift, incorrect tool invocation, reward hacking, positional bias, mode collapse, degeneration loops, alignment faking, and version drift.
LLM Foundational Failure Modes: Hallucination, Sycophancy, Context Rot, Instruction Attenuation
Four LLM failure modes that emerge even in a single prompt. Mechanism, academic evidence, and defense patterns for hallucination and confabulation, sycophancy, context rot, and instruction attenuation.
ADR vs Spec-Driven Development: Why, What, and Using Both
Architecture Decision Records (ADR) and OpenSpec serve complementary roles: ADR answers 'why' a decision was made, spec defines 'what' gets built. How they work together in AI-assisted development.
LLM Behavioral Failure Modes: 12 Failure Patterns and the Defense Map
LLMs forget instructions in long sessions, fabricate information, and agree with you against their own answer. A pillar map of 12 systematic failure modes and the defense layers that address them.
From OpenSpec to Brainstorm + Court: Spec-Driven Workflow with Worktree
Evolution from OpenSpec CLI to a brainstorm + court pipeline, multi-AI evaluation, and parallel spec-driven development with git worktree.
Conversion Rate: Correct Calculation, Common Mistakes, and Optimization
Blended conversion rate is misleading. A CR calculated without segmenting by traffic source, device, and funnel stage does not reflect actual performance.
Customer Journey: From Linear Funnel to Circular Model
The traditional funnel does not cover post-purchase behavior. The McKinsey CDJ model, loyalty loop concept, and journey mapping make it possible to map the entire customer experience.
Customer Statuses: How CRM Definitions Impact Attribution and Forecasting
Lead, MQL, SQL, active, churned. When customer status definitions are misconfigured in your CRM, attribution breaks and forecasting misleads. A guide to getting it right.
Why KISS Is More Relevant Than Ever in the Age of AI Agents
According to Gartner, over 40% of agentic AI projects will be canceled. Why? Unnecessary complexity. Kelly Johnson's KISS principle, defined in the 1960s, plays a more critical role in AI agent architecture than in classical software.
Why SoC Is Critical in AI Agent Architecture
Separation of Concerns is not just a software principle but the fundamental design decision that determines whether an AI agent architecture collapses or stands. Context boundaries, defense layers, and protocol separation.
AI Agent Protocol Guide: MCP, A2A, UCP, AP2, A2UI, and AG-UI
Six open protocols shaping the AI agent ecosystem in 2026. What each one does, how they relate to each other, and practical use-case scenarios.
