# Web Application Development

*Services / Software Development*

> We architect and deliver high-throughput web applications that serve millions of users, integrate with complex enterprise ecosystems, and sustain 99.99% availability under peak load. Our engineering teams combine deep full-stack expertise with rigorous architectural discipline to produce systems that scale with your ambitions. Every engagement is governed by measurable SLAs tied directly to business outcomes.

## Overview

Enterprise web applications are no longer tactical tools — they are core revenue infrastructure. A poorly architected platform that buckles under demand, exposes sensitive data, or requires months to extend costs far more than its initial build. Claritas engineers design for horizontal scale from day one, applying distributed-systems patterns that Fortune 500 organisations depend on to process billions of transactions annually. Our engagement model aligns incentives through milestone-based delivery, transparent technical governance, and post-launch SRE support that keeps your platform performing as usage grows.

## Our Approach

### 1. Discovery & Architecture Blueprint

We conduct a structured discovery sprint with your product, engineering, and compliance stakeholders to map business requirements to a documented architecture blueprint — covering data flows, integration touchpoints, security boundaries, and scalability ceilings.

### 2. Technology Selection & Risk Assessment

We evaluate build-vs-buy trade-offs, OSS licensing constraints, and vendor lock-in exposure before recommending a technology stack. Every selection is backed by a written risk register approved by your CTO or engineering leadership.

### 3. Iterative Build with Executive Visibility

Two-week sprint cadences with live staging environments ensure executive stakeholders can validate progress continuously. Velocity metrics, quality gates, and burndown transparency are provided through your preferred project governance tooling.

### 4. Security, Performance & Compliance Hardening

Prior to release, every application undergoes penetration testing, Core Web Vitals optimisation, and compliance validation against applicable frameworks (SOC 2, ISO 27001, GDPR, HIPAA). No system ships without a signed security sign-off.

### 5. Hypercare & SRE Handover

The first 90 days post-launch include dedicated SRE coverage, incident response runbooks, on-call escalation paths, and a formal knowledge-transfer programme to your internal engineering team — eliminating single points of dependency.

## Capabilities

- Full-stack architecture design for enterprise scale (React, Next.js, Node.js, Go, Python)
- Distributed microservices and event-driven system design
- PostgreSQL, MongoDB, Redis, and multi-region database architecture
- Enterprise SSO, OAuth 2.0, and role-based access control
- GraphQL federation and RESTful API platform development
- Real-user monitoring, distributed tracing, and SLO enforcement
- Automated testing pyramids: unit, integration, E2E, and contract testing
- Zero-downtime deployment strategies (blue-green, canary, feature flags)

## Outcomes

| Metric | Value |
| --- | --- |
| Uptime SLA | **99.99%** |
| P95 API response target | **<200ms** |
| Median throughput improvement on modernised platforms | **10×** |
| Average time to production-ready MVP | **6 wks** |

## Next Step

**Your platform should be a competitive moat, not a liability.**

Engage our enterprise engineering team to architect a web application that scales to your ambitions — built with the rigour and transparency that Fortune 500 technology leaders demand.
