If you’ve ever been nervous about deploying code on a Friday, trust me — you’re not alone. A few years ago, I was leading a team at a major e-commerce company, wrangling a monolithic beast that could break in a hundred creative ways. The idea of microservices was everywhere, but nobody really tells you about the messy parts. Here’s what we learned the hard way — warts and all — while moving from monolith to microservices.

AI agents are reshaping how software is written, scaled, and experienced , and many expect the technology to unlock the gains AI firms have long promised. While most companies today remain in the “testing” phase , as agents make their way throughout the organization, workers will need to figure out how to integrate them into their workflows.

Big data systems are growing in size, speed, and complexity — but the trust we place in them often lags behind. While engineers and analysts build pipelines to move petabytes of data, there's an unspoken assumption: that the data is clean, correct, and complete. Unfortunately, that assumption often breaks in production. From AI models trained on incorrect labels to business dashboards displaying misleading KPIs, untrustworthy data leads to real-world failures.

In the world of finance, ensuring accuracy and compliance in financial records is a critical function. One of the key challenges faced by financial institutions is ledger reconciliation, which involves matching transactions across multiple data sources to detect inconsistencies, errors, and fraud. Traditional reconciliation methods, largely rule-based and manual, are often inefficient, slow, and unable to handle the vast amount of financial data generated daily.
