Backend Technology Stack
A comprehensive breakdown of the languages, frameworks, databases, and architectural patterns I utilize to build resilient server infrastructure.
Core Runtimes & Frameworks
Building scalable, maintainable server applications with modern TypeScript & Node ecosystems.
Event loop optimization, cluster modules, stream pipelines
Modular architecture, dependency injection, microservices, guards
Strict typing, generics, DTO validation, interface design
REST routing, middleware chains, error handling, performance
Databases, ORM & In-Memory Caching
Designing high-performance schema models, query optimizations, and caching layers.
Indexing, relational modeling, complex joins, transactions
Session storage, key-value caching, Pub/Sub, rate limiting
NoSQL document schemas, aggregation pipelines, indexing
Schema migrations, type-safe queries, relation mapping
Infrastructure, DevOps & Tooling
Containerizing services, managing proxies, automated testing, and API specifications.
Multi-stage Dockerfiles, docker-compose, container networking
Reverse proxying, load balancing, SSL termination
Unit testing, integration testing, API mock suites
Interactive API docs, Swagger annotations, client codegen
Architectural & Security Patterns
Enforcing security standards, robust authorization, and asynchronous event flows.
Clean URI design, pagination, sorting, HATEOAS, schema stitching
OAuth2, bcrypt hashing, Refresh Token rotation, Role guards
Event-driven architecture, message queues, decoupled services
Feature branching, pull requests, semantic release workflows
