Database Design & Backend Architecture
The foundation your application will never outgrow.
We design relational and document database schemas, engineer REST APIs, and architect backends that are fast, secure, and built to scale — the invisible layer that keeps your application reliable under load.
Architected for resilience. Engineered for velocity.
Every application we build is only as good as its backend architecture. For EduVeera we designed a PostgreSQL schema handling students, admissions, counselling sessions, documents, courses, universities, and application workflows — all interconnected with foreign keys, indexed for query performance, and secured with role-based access. For Keshera Industry we designed a schema that manages inventory, purchasing, sales, invoicing, and employee data across departments. We treat database and backend design as the most important decisions in any project — because they are the hardest to change later.
At MARK 2, we reject brittle templates and technical shortcuts. Every system we build is designed as a mission-critical asset, giving your product team the speed, security, and scalability needed to outperform competition.
Who Is This Service Designed For?
Traditional Bottlenecks vs. MARK 2 Engineering
Your database queries are slow and the application becomes unusable as data grows
We audit your schema, add missing indexes, rewrite inefficient queries, denormalise where appropriate, and implement caching — with measured query time improvements at each step
Your database schema was designed without relationships and everything is duplicated
We redesign the schema with proper normalisation, foreign key relationships, and referential integrity — then migrate existing data safely
Your backend has no authentication and the API is wide open
We implement JWT-based authentication, role-based access control, input validation, rate limiting, and OWASP Top 10 hardening across every endpoint
There is no documentation for your APIs and new developers take weeks to understand the system
We generate Swagger/OpenAPI documentation from code — every endpoint described with request/response schemas, authentication requirements, and example payloads
Live Architecture & Runtime Blueprint
Explore how we structure edge compute, domain logic, data models, and enterprise security.
Sub-millisecond global routing and distributed edge computation.
- Dynamic Edge Prerendering & Streaming Server-Side Rendering (SSR)
- Multi-region Cloudflare / AWS edge CDN with localized micro-caching
- Automatic Brotli / AVIF compression and asset pre-fetching
// Edge Middleware Cache & Auth Route
export const config = { matcher: '/api/v1/:path*' };
export default async function middleware(req: NextRequest) {
const edgeGeo = req.geo?.region || 'global-iad';
const cachedResponse = await edgeCache.get(req.url);
if (cachedResponse) return cachedResponse.withHeader('X-Edge-Hit', 'true');
return executeDistributedRoute(req, { latencyTargetMs: 40 });
}What We Build & Deliver
End-to-end full lifecycle engineering execution tailored to your specific scale requirements.
Relational Schema Design (PostgreSQL)
Normalised schema design with proper foreign keys, indexes, constraints, and data types — optimised for the specific query patterns of your application
Document Schema Design (MongoDB)
Flexible document schema design for content-driven or rapidly evolving data models — including aggregation pipelines and indexing strategy
REST API Engineering
Resource-oriented REST API design with consistent naming conventions, proper HTTP methods, status codes, and pagination — built on Spring Boot or Node.js
Authentication & Security
JWT tokens, refresh token rotation, RBAC middleware, input sanitisation, SQL injection prevention, and rate limiting — security built in at every layer
Query Optimisation
EXPLAIN ANALYSE on every critical query, appropriate indexing strategy, N+1 query elimination, and connection pooling configuration
Database Migration Strategy
Version-controlled migration scripts using Flyway or Liquibase — every schema change tracked, reversible, and deployable without downtime
Concrete Deliverables You Own
Zero lock-in. Complete source repositories, typed contracts, CI/CD deployment pipelines, and comprehensive technical runbooks.
Business & Technical ROI
Engineering decisions designed to maximize revenue, user retention, and operating efficiency.
Queries That Stay Fast
Proper indexing and schema design ensures queries remain fast as your data grows from thousands to millions of records
Security From Day One
Authentication, input validation, and OWASP hardening implemented as foundation — not added as an afterthought after a security incident
Easy to Extend
A well-designed schema and documented API make adding new features, modules, and integrations straightforward instead of painful
Full Documentation
Every API endpoint documented, every table described, every relationship explained — so any developer can understand and work with the system
The Milestone Engineering Roadmap
A structured, transparent delivery methodology with zero black-box timelines.
Data Modelling
We identify every entity, attribute, and relationship in your domain — then design the schema with normalisation, referential integrity, and performance in mind
API Contract Design
Resource naming, endpoint structure, request/response schemas, authentication model, and error format defined and documented before implementation
Backend Implementation
Database creation, API endpoints, authentication, business logic, input validation, and error handling implemented with test coverage
Performance Testing
Load testing, query profiling with EXPLAIN ANALYSE, index tuning, and connection pool optimisation under simulated production load
Documentation & Handover
Swagger documentation, ERD diagram, deployment instructions, and environment configuration guide delivered with the codebase
