Fast, secure, and scalable backend services using Rust and JavaDennis Njuguna
I offer custom backend development services using Rust and Java, tailored for performance, reliability, and scalability. Whether you're building a new product or need to upgrade your existing backend, I specialize in designing systems that are secure, testable, and built to last. What sets me apart is my expertise in event-sourced architectures, temporal systems, and clean, production-ready code.
What's included
𧩠Backend Architecture Design
A modular, scalable, and maintainable system blueprint tailored to your productâs goalsâincludes documentation, database schema design, and service layout using best practices.
đ REST or GraphQL API Development
Production-grade APIs built with Actix-Web, Salvo (Rust) or Spring Boot (Java), including route handlers, authentication, validation, and clean documentation (e.g., OpenAPI/Swagger).
đ Database Integration & Migrations
Schema design, migration scripts, and optimized queries using PostgreSQL, SQLite, or MySQLâpowered by tools like Diesel (Rust) or JPA/Hibernate (Java).
đ File Upload & Storage Service
Secure multipart file upload backend with metadata indexing, file streaming, and pluggable storage support (local, S3, etc.), written in Rust or Java.
đ§Ș Testing & Quality Assurance
Unit tests, integration tests, and performance benchmarks to ensure reliability, security, and stability under loadâusing cargo test, JUnit, etc.
đ Dockerized Deployment-Ready Codebase
Containerized backend service setup with Docker, including dev/test/staging environments and basic CI/CD configuration for smooth deployment.
â± Temporal or Event-Sourced Backend Modules
Custom event-sourced systems (like temporal graph databases or audit trails) using immutable logs and time-aware querying capabilitiesâgreat for legal, compliance, or intelligence use cases.
