JanPereiraDev

JanPereiraDev is an independent software publisher focused on developer tooling for the emerging field of AI-assisted software engineering. Its flagship offering, QUANTUM_LOG, addresses the growing need for observability and cost management in workflows built around AI coding agents. As development teams increasingly delegate coding tasks to autonomous or semi-autonomous agents, tracking what those agents do, how much they consume in terms of compute and API calls, and where inefficiencies arise becomes a significant operational challenge. QUANTUM_LOG tackles this problem with a local-first architecture, meaning that logs, traces, and usage data are captured and stored on the user's own machine rather than being transmitted to external servers, which is particularly valuable for organizations with strict data privacy or compliance requirements. The product combines observability capabilities such as monitoring agent behavior, recording prompts and responses, and diagnosing failures with FinOps functionality that helps users understand and control spending on large language model APIs and related infrastructure. Typical use cases include individual developers auditing their agent sessions, engineering leads analyzing token consumption across projects, and teams seeking to optimize their AI-assisted development pipelines without sacrificing data sovereignty. By unifying visibility and cost governance in a single locally hosted tool, QUANTUM_LOG aims to make AI coding agents more transparent, accountable, and economical to operate at any scale of adoption.
