Expletech is a premium backend development studio creating reliable and scalable API systems.
Backend that handles billions of requests
We build scalable APIs, microservices, and databases. Node.js, NestJS, Go — with 99.9% Uptime and Response Time <100ms guaranteed.
Hidden technical debt limits your growth
A fragile backend will inevitably crash when you need it most, leading to data loss and damaged reputation.
Frequent Downtime
Unoptimized databases and monolithic architectures buckle under traffic spikes.
Security Risks
Outdated backends are prime targets for data breaches and compliance violations.
Integration Headaches
Rigid systems make it nearly impossible to connect with modern third-party APIs.
Slow Processing
Inefficient queries and lack of caching result in agonizing load times.
Backend that handles
massive workloads
Our backend engineers build resilient, scalable systems from scratch. We design flawless database architecture, robust APIs, and microservices to support the rapid growth of your business.
Microservices & Serverless
Scalable architecture. Flexible separation of business logic into independent services, easing scaling and updates.
Data Layer First
Query optimization. Building reliable relational and NoSQL data structures for fail-safe handling of millions of records.
Enterprise Security
Absolute security. Protection from injections, DDoS, modern encryption, and strict adherence to OAuth 2.0 standards.
@Injectable()
export class DataService {
// 1. Optimized connection pooling
constructor(private readonly db: DatabaseConnection) {}
async fetchWithDetails(id: string) {
// 2. High-performance caching
const cached = await this.db.cache.get(id);
if (cached) return cached;
// 3. Complex relational operations
const data = await this.db.transaction.execute();
return data;
}
