Custom Platforms & Portals

Replace spreadsheet chaos with unified tools.

We build the digital backbone of your operations. Whether it's a client-facing portal or an internal line-of-business application, we deliver a unified platform tailored to your specific goals, replacing disjointed legacy tools.

Systems Integration & API Engineering

Stop the manual double-entry.

Your software shouldn't live in a silo. We engineer the hardened, secure connections that allow your new solution to sync perfectly with your existing ERP, CRM, and payment gateways.

Universal Access (PWA)

Build once, run everywhere.

We utilize Progressive Web App (PWA) technology to deliver a native-app experience across desktops, tablets, and phones. This ensures your team stays efficient in the field or the office—without the friction and delay of App Stores.

Digital Workflows & Governance

Codify your business logic.

We bake your specific operational rules directly into the software. By managing approvals, routing, and role-based permissions (RBAC), we ensure security and create a clean, audit-ready history for every action.

AI-Ready Architecture

Future-proof your operations.

We design your software to accommodate practical automation and AI agents from day one. We implement the logic to handle heavy data processing and repetitive admin tasks, keeping your team focused on high-value work.

Operational Visibility

Know where your business stands.

Stop guessing. We embed custom admin panels and reporting modules directly within your application, giving you real-time oversight of system activity and critical KPIs without needing external BI tools.

05  Our stack

Technology expertise

Front-end Architecture

Angular • TypeScript • SASS

Maintainable by Design.

We build strict, type-safe interfaces using Angular and TypeScript to ensure your application remains stable as it grows. We create modular UI systems styled with modern SCSS, delivering a responsive experience that looks great on any screen size.

Back-end Services

C# .NET • Node.js • Python

Logic & Performance.

We select the right tool for the job. We utilize .NET for hardened, complex business rules and Node.js for high-concurrency event handling. Our architectures rely on secure RESTful APIs to ensure fast, reliable data exchange.

Multi-Platform (PWA)

Ionic • Service Workers • Offline Storage

Native Power, Web Delivery.

Get mobile capabilities without the App Store friction. We use Ionic and modern PWA standards to deploy cross-platform applications that leverage device hardware (camera, GPS) and function reliably even in offline environments.

Data Persistence

SQL Server • PostgreSQL • Redis

Integrity First.

Your data is your most valuable asset. We structure it using ACID-compliant relational databases (SQL Server, Postgres) for absolute reliability, while deploying Redis for high-speed caching and instant session management.

Cloud & DevOps

Managed Cloud • CI/CD • Regional Hosting

Secure & Compliant.

We provide fully managed cloud environments protected by automated CI/CD pipelines. We configure hosting in your specific region (EU/UK/US) to ensure low latency and strict compliance with data sovereignty and GDPR.

Ecosystem Integrations

Stripe • Twilio • ERP/CRM • Webhooks

Seamless Connectivity.

We don't use fragile workarounds. We implement deep SDK integrations for payments (Stripe) and communications (Twilio), alongside custom webhook handlers that securely bridge your new software with your existing ERP or CRM.

FAQs

We focus on established businesses and SMEs with validated operational workflows and clear requirements.

Note: We do not work with early-stage startups or on "idea-stage" MVPs. Our engineering process is optimized for digitizing and scaling existing business operations.

We do not. To guarantee stability and maintainability, we only engage on greenfield builds or full rebuilds.

If you have a legacy system that needs replacing, we execute a parallel rebuild: we engineer the new platform alongside your current one, ensuring a safe migration and cutover without disrupting daily operations.

Yes, but with clear boundaries. We collaborate closely on architecture, security standards, and API specs to ensure the software fits your ecosystem.

However, to maintain velocity and accountability, Happen Software retains exclusive ownership of the development process. We do not support "mixed-team" coding environments. We build it, test it, and hand it over fully certified.

We work in rapid, transparent cycles.

  • Targeted Tools: 4–8 weeks.
  • Full Platforms & Portals: 8–16+ weeks.
  • We agree on milestones upfront and ship increments continuously so you can see progress, not just promises.

We operate with commercial certainty. You can choose between a Fixed-Scope engagement (for well-defined builds) or Monthly Squad pricing (for evolving requirements).

In both cases, you get a capped budget, clear inclusions/exclusions, and a signed acceptance checklist before final billing.

We offer two paths:

  1. 1.Managed Service: We retain responsibility for uptime, security patching, and continuous improvement under an SLA.
  2. 2.Handover: We execute a structured transition to your internal team, providing code walkthroughs so they can take the reins.

Yes. We are enterprise-ready from day one. We are accustomed to signing NDAs/DPAs, completing security questionnaires, and aligning hosting environments to meet strict data residency and GDPR requirements.

We routinely support enterprise security and procurement processes, including NDAs, DPAs, GDPR compliance, and data residency requirements. Our approach is designed to be straightforward and efficient, minimizing administrative overhead while meeting strict compliance standards.
