Challenge
Seasonal stability under 10x load
Traffic and checkout volume routinely spike to ~10x baseline during gifting peaks. The platform has to absorb that surge cleanly — no queueing, no failed checkouts, no degraded experience.

Overview
GiftCrowd
GiftCrowd is a group gifting platform that lets organizers pool contributions online, invite participants, and let recipients redeem from 450+ top brands. It powers teacher appreciation, school events, workplace gifting, and personal milestones across the US — free for organizers and contributors.
The business runs on two extreme seasonal peaks: Teacher Appreciation Week in May–June and the Winter Holiday window in November–December. During these windows, traffic and transaction volume can spike to roughly 10x baseline, and every single failure is a refund, a support ticket, and a damaged moment. Mejix was brought in to make that surge a non-event.
Why executives care
A gifting platform that fails on Teacher Appreciation Week or Christmas Eve doesn't just lose revenue — it loses the moment. The Mejix engagement exists to make sure that never happens.
Challenges
The Challenge
Challenge
Multi-party money flows
Every campaign involves contributors paying in, organizers managing the pool, and recipients redeeming out — across multiple providers. The accounting, reconciliation, and fraud surface area is significantly larger than a normal checkout.
Challenge
Provider redundancy across 9 integrations
5 payment processors and 4 gift card networks all have to behave like one product. If one provider degrades mid-peak, the platform has to fail over without the buyer ever knowing.
Challenge
Zero-downtime modernization
The frontend stack needed a full move to Angular 18 while the platform continued processing live transactions 24/7. We couldn't take a maintenance window — there isn't one.
Challenge
Fraud and trust at multi-party scale
Pooled funds, gift card payouts, and high gifting-season volume make GiftCrowd an attractive target. Fraud controls needed to be strong enough for finance, invisible enough for the average parent organizing a class gift.
Approach
How we turned the concept into a working product
Mejix operates as a fully embedded engineering team built around a single operating principle: stability first, scalability second, features third. Every release is judged against that order, and seasonal planning is aligned to the gifting calendar instead of an internal sprint clock.
On the platform side, that translated into a modernized Angular 18 SPA and admin portal, a multi-provider payment stack with automatic fallback, real-time integrations with four gift card networks, and an AWS-native infrastructure tuned for predictable peak behavior rather than average load.
Solutions
A platform engineered for the peak, not the average
Four systems working together — modern frontend, redundant payments, multi-network gift card fulfillment, and elastic infrastructure — so peak season behaves like any other day.
Angular 18 SPA + Admin Portal
A modern TypeScript + SCSS frontend with Material UI and AG Grid replacing the legacy stack, plus an internal admin portal for campaign management, support, and operational visibility — shipped without a single production interruption.
Multi-Provider Payment Stack
Five payment processors — Stripe as the primary, PayPal as a fallback, Venmo, and BNPL options (Affirm, Klarna, Afterpay) — orchestrated behind one checkout, with webhook handling and reconciliation that keeps finance teams sane during peak weeks.
Four Gift Card Network APIs
Real-time integration with Runa, PerfectGift, Blackhawk Network, and Incomm — 450+ redeemable brands with live catalog sync, instant digital fulfillment, and automated redemption flows for recipients.
AWS-Native Peak-Ready Infrastructure
Load-balanced EC2 behind an ALB, RDS SQL Server with 35-day backups, SQS-driven async processing, and Lambda for background workloads — provisioned and rehearsed against the gifting calendar so peak weeks run on a known-good plan.
Technology
Technology stack
Angular 18 + TypeScript 5
Modern SPA frontend with Material UI and AG Grid, replacing legacy code without disrupting live operations.
C# .NET 8 (REST API)
The transactional backend powering payments, campaigns, multi-party flows, and gift card orchestration.
AWS RDS (MSSQL) + Entity Framework Core
Managed SQL Server with 35-day point-in-time recovery and a clean data layer built for high-write transactional load.
AWS EC2 + ALB + Amplify CI/CD
Load-balanced application tier with automated deployment pipelines — zero-downtime releases as a default, not a feature.
AWS Lambda + SQS + Quartz
Async work, webhook fan-out, scheduled jobs, and peak-time queue absorption so user-facing checkout stays fast.
Stripe, PayPal, Venmo, Affirm, Klarna, Afterpay
Five payment rails behind one checkout experience, with intelligent routing and graceful fallback.
Runa, PerfectGift, Blackhawk, Incomm
Four gift card networks delivering 450+ redeemable brands with real-time availability and instant fulfillment.
CloudWatch + Sentry observability
End-to-end monitoring across infrastructure, application, and payment webhooks — every anomaly is alerted before it becomes a support ticket.

Every architectural decision is judged against peak-week behavior. Stability first, scalability second, features third — in that order, every time.
03
Seasonal calendar planning
Roadmap, releases, and on-call rotations align with Teacher Appreciation Week and Winter Holidays, not with an internal sprint cadence.

What's next
Where the platform goes from here
The next phase of the GiftCrowd engagement focuses on widening the brand catalog, deepening B2B and enterprise gifting workflows, and pushing more of the operational layer into self-serve admin tooling — all without compromising the stability-first principle that defines the platform today.
On the engineering side, that means continued investment in observability, automated peak-load rehearsals ahead of each seasonal window, and incremental modernization of the .NET service surface as the product grows.
