// CODE EXERCISES

Practice. Explain. Improve.

Sample exercises for my stack. Prompts and approaches—not a record of completed solutions.

5 sample exercises

JavaScriptSample exercise

Limit concurrent async tasks

Process a batch of tasks without starting everything at once.

Node.jsPromises

Explore the exercise

Prompt: Design a task runner with a configurable concurrency limit. Preserve result order and decide how failures should be reported.
Approach: Use a small worker pool over a shared task index. Keep the API explicit about fail-fast versus collecting errors.
What to check: Cover an empty batch, a limit larger than the batch, invalid limits, and rejected tasks.

BackendSample exercise

Remove repeated GraphQL lookups

Spot repeated data access in a nested API request.

GraphQLAPI design

Explore the exercise

Prompt: A page requests a list of documents and the author of each document. Explain how to avoid a separate author lookup for every row.
Approach: Collect author IDs, fetch them in a batch, and map results back to the requested order. Keep any request cache scoped to the current caller.
What to check: Include repeated author IDs, missing authors, access rules, and a batch failure.

ReactSample exercise

Separate server data from UI state

Give remote records and local workflows clear owners.

ReactTanStack QueryRedux

Explore the exercise

Prompt: Design a property dashboard with remote property records, a multi-step form, filters, and a selected property.
Approach: Explore query caching for remote records and a client-state store for the local workflow. Document why each value belongs in its chosen place.
What to check: Walk through refresh, a failed save, optimistic changes, and returning to an unfinished form.

StreamingSample exercise

Correlate events in a time window

Group related signals before creating an incident.

FlinkEvent-driven systems

Explore the exercise

Prompt: A fictional network produces repeated alarms for related devices. Define an incident-correlation strategy over a ten-minute window.
Approach: Choose correlation keys, define event-time behavior, and describe a policy for duplicate and late events.
What to check: Consider out-of-order events, a noisy device, replayed messages, and state cleanup.

DSASample exercise

Find a maximum sliding-window sum

Find the largest sum across fixed-size slices of an array.

ArraysSliding window

Explore the exercise

Prompt: Given an array of numbers and a valid window size k, return the largest sum of any consecutive k values.
Approach: Compute the first window, then subtract the outgoing value and add the incoming value as the window moves.
What to check: Include all-negative values, k equal to one, a full-array window, and invalid k.
