Engineering Through Code

Code Samples.

A collection of representative examples from systems I've designed and built, demonstrating how I approach architecture, application development, data access, algorithms, and maintainable software.

Featured Samples

Representative implementations from Week at Work, Loyal Guests, and related engineering projects.

Application Logic C#

Finalizing Shift Trade Approval

Finalizing shift trade approvals while validating schedule conflicts, coordinating approval groups, and applying give-up or swap changes.

var allApprovals = await _shiftTradeRepository
        .GetAllApprovalsForTradeRequestAndResponse(
            command.TradeRequestId,
            userTradeApproval.TradeResponseId);

var groupedApprovals =
    allApprovals.GroupBy(a => a.ApprovalGroup);

if (groupedApprovals.All(group =>
    group.Any(a =>
        a.IsFinalizer &&
        a.Decision == TradeDecision.Approved)))
{
    tradeRequest.TradeStatus =
        TradeStatus.Approved;

    await _shiftTradeRepository
        .UpdateShiftTradeRequest(tradeRequest);
}

Scheduling Algorithm C#

Rule-Driven Break Scheduler

Transforming configurable meal and rest rules into legal, conflict-free break placements while accounting for employee eligibility, rolling work windows, and break suppression.

var applicableRules = rules.Where(r =>
        RuleApplies(r, user, shiftStart));

var required = applicableRules
    .SelectMany(rule =>
        GenerateRequiredBreaks(
            rule,
            shiftStart,
            shiftEnd))
    .ToList();

var ideals =
    CalculateIdealTimes(
        required,
        shiftStart,
        shiftEnd);

var placed =
    PlaceBreaks(
        ideals,
        shiftStart,
        shiftEnd);
