1. Software Development

Executes database migrations for the stripe-sync-engine, including schema updates and table creation as specified by user commands.

Transforms approved plans into production-ready code. Activates on commands like 'let's build' or 'start coding' to execute development tasks.

Troubleshoots Stripe sync engine issues including webhook errors, signature failures, and connection problems in payment integrations.

Standardizes Java backend project structure including repository layout, module boundaries, and naming conventions for consistent development.

Builds and tests Rust-Python bindings using PyO3 and maturin, enabling seamless interoperability for extension development.

Performs code reviews emphasizing readability, maintainability, and clarity to ensure high-quality code before merging into the main branch.

Provides form patterns and validation utilities for Composable Svelte, including Zod integration, field-level validation, and reactive state management.

Assists in restructuring code for improved readability and maintainability without altering functionality, responding to user requests for refactoring or cleanup.

Provides development support for Python applications using modern tools like uv, functional programming patterns, and production best practices.

Guides design and refactoring of high-signal, reliable, maintainable tests across unit, integration, and end-to-end suites.

Enforces React coding standards for hooks, state management, and performance in component development.

Provides a JDBC performance playbook for optimizing database interactions in Java, including connection pooling, batching, and benchmarking.

A workflow for profiling Java application performance using JFR and async-profiler to capture, analyze, and resolve CPU and latency issues.

AI-powered notebook enabling frontend developers to practice coding, receive instant answers, and track progress in real-time development workflows.

Provides a deterministic Java configuration system with layered sources, validation, and runbooks to manage environment-specific settings and secrets safely.

Defines testing strategies (unit, integration, end-to-end) based on repository risk and maturity to improve coverage and plan new features.

Identifies bottlenecks, latency, and resource usage to optimize application performance.

Enables distributed tracing in Java microservices using OpenTelemetry for debugging latency, dependency failures, and request flows across services.

Enforces TypeScript/JavaScript coding standards to ensure type safety, proper async handling, and clean code style in development projects.

Configures and optimizes Gradle builds for Java backend projects, addressing multi-module structures, performance, and reproducibility.

Provides utilities for implementing resilience patterns including retries, circuit breakers, and timeouts to handle failures in software systems.

Provides Python development best practices, code standards, architectural patterns, and conventions for the MCP project.

Guides selection and implementation of Java concurrency models (thread pools vs virtual threads) for optimizing throughput and handling blocking I/O.

Provides a Java implementation of the transactional outbox pattern with idempotency to ensure exactly-once event delivery and prevent double-publishing in distributed systems.
