- [Building Cookieless Web Telemetry with ClickHouse and SigNoz](https://itspedrodias.com/posts/clickpulse-cookieless-telemetry-clickhouse/) (2026-10-13): Running a secondary relational database or paying for hosted analytics just to count website hits feels redundant when ClickHouse is already in your stack.
This is an architectural walkthrough of building a cookieless telemetry pipeline with Cloudflare Workers, a D1 fallback buffer, and native SigNoz dashboards.


- [Beyond the SELECT: Object-Centric Debugging with URNs and Safe AI Triage](https://itspedrodias.com/posts/mcp-urn-debugging/) (2026-09-26): In distributed systems, the debugging tax isn't the fix; it's the navigation. Learn how Uniform Resource Names (URNs) and the Model Context Protocol (MCP) enable safe, deterministic AI triage with verifiable audit trails.


- [From O(n) to O(1): How We Made DataFrame Lookups 23x Faster](https://itspedrodias.com/posts/data-processing/) (2026-01-08): We optimize APIs. We scale databases. We architect systems for speed.
But sometimes the biggest performance wins hide in plain sight, in a single function called thousands of times.


- [The Observability Pipeline: Taming Your Observability Costs](https://itspedrodias.com/posts/observability-pipelines-cost-control/) (2025-10-21): Your observability bill is out of control because you're sending everything to your vendor. It's time to take back control with an observability pipeline: a central hub to filter, shape, and route your telemetry data, slashing costs and breaking vendor lock-in.


- [Beyond the Key: The Power and Peril of End-User IDs](https://itspedrodias.com/posts/beyond-the-key-end-user-ids/) (2025-10-05): You've isolated your services with unique API keys. But what about the users behind them? This article explores the next layer of observability: passing end-user IDs to third-party APIs, and the critical balance between visibility and privacy.


- [The Hidden Dangers of Sharing API Keys Across Services](https://itspedrodias.com/posts/one-key-to-rule-them-all/) (2025-10-03): Reusing a single API key across multiple applications seems efficient, but it creates a nightmare for observability, reliability, and security. This post breaks down why this common anti-pattern is so dangerous and why unique keys are essential for robust systems.


- [Beyond the Demo: An Engineer's Short Guide to Choosing Tools, Not Vendors](https://itspedrodias.com/posts/choosing-tools-not-vendors/) (2025-09-29): Choosing a third-party service is an architectural decision, not just a purchase.
This is a guide for engineers to navigate the procurement process, separating the technical evaluation from the sales relationship to avoid long-term traps.


- [The Datadog Bill You Didn't See Coming: APM's Hidden Costs](https://itspedrodias.com/posts/datadogapmcost/) (2025-04-15): Datadog is a powerful observability platform, but its true cost often lies hidden in the interconnectedness of its features.
Let's explore how one decision, like enabling APM, can lead to a cascade of unexpected expenses.


- [The Accidental Bottleneck: When Managers Turn into Human Load Balancers](https://itspedrodias.com/posts/lbmanagement/) (2025-03-25): We optimize code. We scale databases. We architect systems for speed and resilience.
But what if the real performance bottleneck in the org… is a person?


- [Investing in Value: Aligning Software Efforts with Business Impact](https://itspedrodias.com/posts/valueinsoftware/) (2025-01-29): An idea to simplify your decision making with value quadrants
