EventStripe

EventStripe is a modern event management and ticketing platform that enables organizers to create events, sell tickets, and process payments worldwide within minutes — either through their own EventStripe page or integrated into existing websites. H-Studio was responsible for the complete technical platform: backend architecture, payment infrastructure, scaling, monitoring, and operational stability.

Challenge

EventStripe faces two difficult worlds:

• Extremely high load peaks during ticket releases
• For popular events, thousands of users must simultaneously reserve, purchase tickets, and complete payments — without the platform breaking down.
• International payment processing
• 50+ payment methods, multiple currencies, different tax logics, and regional payment providers had to work together reliably.
• Dynamic ticket and pricing logic
• Early-bird pricing, tiered prices, promo codes, reservations, time limits, and automatic releases are critical core functions.
• High requirements for availability and transparency
• Organizers need live analytics, payment reports, accounting documents, and reliable payouts.
• Mobile UX & CI/CD
• Event pages must be creatable within 30 minutes — mobile-optimized, fast, and error-free. New features must be continuously deployable.

Our Approach

We developed a modular microservice platform with Kubernetes infrastructure, international payment integration, and a complete observability system.

1. Microservice Architecture for Tickets, Pricing, Payments, and Analytics

We developed a modular microservice platform consisting of clearly separated areas:

• Ticket Service – quotas, reservations, queues, QR code generation
• Pricing Service – dynamic prices, discount logic, promotions, VAT rates
• Payment Service – international payment processing, webhooks, retry & idempotency
• Payout Service – accounting, payouts, documents for bookkeeping
• Notification Service – email, webhooks, internal system notifications
• Analytics Service – live metrics, conversion tracking, event performance
• API Gateway – central routing, authentication, rate limits, throttling

Each area is autonomously scalable and independently deployable — perfect for high load peaks.

2. Kubernetes Infrastructure with Automatic Horizontal Scaling

The platform runs completely on Kubernetes:

• automatic scaling of critical services
• rolling deployments without downtime
• pod self-healing on errors
• isolated namespaces for staging, sandbox, and production
• optimized resource distribution for traffic peaks

During highly demanded events, Kubernetes scales up additional capacity, processes the peak, and automatically scales back down afterward.

3. International Payment Infrastructure

The payment area was developed so EventStripe can scale globally immediately:

• support for 50+ international payment methods
• multiple payment providers in parallel (fallback & provider prioritization)
• webhook signatures & validation
• automatic retry of failed requests
• idempotent payment processes (no double bookings)
• reconciliation jobs for alignment between tickets, payments, and payouts
• tax-compliant documents (country-specific)

Special focus was placed on ensuring no single payment loss occurs — a critical factor in ticketing.

4. Features for Organizers, Venues, and Guests

The platform was designed so organizers can operate professional ticket pages without developers.

• Events Calendar Page – branded event calendars with domain, logo, artists; integration of YouTube, Tripadvisor, Google Maps
• Event Page – live in 30 minutes; mobile-optimized; styling for music integrations (SoundCloud, Spotify, Apple Music)
• Admin Panel – management of events, tickets, prices, payments; three-level analytics: Workspace → Events → Ticket sales; full control over payouts
• Ticket Buyer Profile – personal dashboard for all tickets; past & upcoming events; individual promo offers
• QR Scanner & Check-in – live check-in; real-time data synchronization; prevention of multiple scans

5. Observability & Monitoring

The platform uses a complete observability system:

• ELK Stack (Elasticsearch, Logstash, Kibana)
• Grafana dashboards with live metrics
• alerts via Slack for anomalies (e.g., payment errors, increased latency)
• detailed logging pipelines
• real-time monitoring of every critical component

This allows the team to detect problems before users notice them.

6. CI/CD & Deployment Security

We implemented a robust release pipeline:

• Jenkins CI/CD
• automated tests, linting, security checks
• canary and blue-green deployments
• automatic rollbacks
• preview environments for the UX team

New features can thus be continuously and risk-free rolled out.

Results

• 10,000+ parallel sessions during ticket releases
• Response times of < 120 ms under peak load
• 100% automatic scaling & self-healing
• Reliable global payment processing
• Complete transparency for organizers (live analytics & reporting)
• Foundation for new enterprise features and white-label solutions

Technical Stack

Why This Project Matters

• EventStripe demonstrates that a modern event platform can simultaneously be:
• extremely scalable
• internationally payment-capable
• technologically cleanly separated
• and easy to use for organizers
• The architecture proved that enterprise-level stability and startup speed are not contradictory. Many of the concepts — microservices, observability, payments, API gateway — are now a fixed part of H-Studio's infrastructure blueprints for SaaS companies and high-load products: fast to develop, easy to extend, hard to break.
