Plan product analytics with event tracking, conversion funnels that reveal drop-offs, and retention analysis by user group. Includes PostHog examples and guidance for evaluating A/B tests, defining a core product metric, and designing dashboards.
Design APIs and interfaces between parts of an application with clear input and output types, consistent errors, and predictable names. The guidance helps you extend existing interfaces while preserving compatibility for the code that uses them.
Design AI agents that use tools, plan tasks, retain relevant context, and recover from failures. Choose execution patterns, permission boundaries, memory handling, and runtime limits, and assess whether coordinating multiple agents is justified for the task.
Design modules that hide complex behavior behind a small, clear interface. Use shared design principles to review dependencies, choose where behavior can be swapped, and make code easier to test and maintain.
Plan startup hiring from pre-seed through Series A. Organize roles, reporting lines, salaries, and equity compensation, then estimate staffing costs and hiring timelines around revenue goals, funding milestones, and budget limits.
Design and implement native iPhone and iPad interfaces with SwiftUI using Apple's design guidelines. Covers screen navigation, flexible layouts, system icons, accessibility, adjustable text sizes, and colors that adapt to light and dark modes.
Prepare GRPO reinforcement learning configurations for tasks with programmatically checkable answers, such as math, code, and structured output. Design and inspect reward functions, then select training variants when runs show instability or exploit flaws in scoring.
Implement Python error handling with early input checks, appropriate exception types, and clear messages. Handle individual failures in batch jobs, preserve error context for debugging, and use Pydantic models to validate structured input.
Build and review C#/.NET APIs and business backends using concrete implementation patterns. Cover asynchronous operations, service dependencies, database access, configuration, caching, and tests to structure application code and examine quality and performance issues.
Design CI/CD pipelines that move applications through development, staging, and production. Define approval and security checks, gradual release strategies, health checks, and rollback procedures, and investigate gates or deployments that fail to progress.
Design and review REST and GraphQL APIs with consistent naming, data structures, error responses, pagination for large result sets, and versioning strategies. Helps teams define shared standards and plan changes that existing clients can adopt gradually.
Design or refactor backend services with clear layers and dependency rules. Using Clean Architecture, Hexagonal Architecture, and Domain-Driven Design, it separates business logic from databases and frameworks and defines interfaces that support testing without external services.
Design and implement Saga workflows across services, using compensating actions to undo completed work after failures. Define step deadlines, handle repeated messages safely, and monitor stalled order, booking, or other long-running processes.
Design and review PostgreSQL database schemas by choosing suitable column types, keys, constraints, and indexes. It also guides decisions about large-table partitioning, flexible JSONB data, and schema changes on a live database without downtime.
Create and improve web, mobile, and desktop interfaces in Penpot through connected tools. Reuse existing design patterns, build layouts and components, and inspect designs for readability, accessibility, spacing, and usability.
Plan and explain Lakehouse solutions in Microsoft Fabric, a place to manage tables and files together. Understand data organization, links to data without copying, access controls, and table maintenance options for designing and improving a solution.
Plan tiered administration for Active Directory by separating administrative accounts and systems into three levels. Cover dedicated administration workstations, authentication restrictions, and verification checks to help limit credential theft and the spread of compromise.
Create reusable procedures for responding to security incidents, from detection and containment to recovery. Define decision points, responsibilities, escalation rules, and workflows for security automation platforms so teams can follow a consistent response process.
Design autonomous coding agents using implementation patterns for tool calls, permission checks, browser interaction, and saved task state. Code examples and checklists help structure agent behavior and workflows that include human approval.
Design AI agents that plan tasks, call tools, and retain useful information. Covers coordination between agents, evaluation, and debugging, with practical patterns for execution limits, error handling, and tracing what an agent does.
Refactor React components into reusable pieces with clearer interfaces. Provides patterns for replacing excessive boolean settings, sharing state through providers, and designing component libraries, with additional guidance for React 19 APIs.
Review a design system for inconsistent names and hardcoded visual values, document component variants and accessibility behavior, or propose new interface patterns that follow existing rules. Produce structured audits, component references, and design proposals.
Design new pages and components, audit existing interfaces, or redesign their visual structure. It emphasizes varied layouts, consistent colors and typography, mobile checks, and extracting reusable design characteristics from screenshots or readable web pages.
Manage Jira issues, build JQL searches, and design project workflows and reports. Use bundled scripts to generate search queries and check workflow designs, with guidance on which operations require Jira’s interface or API.
