Backend Engineer  ·  API Design & Server Architecture  ·  Indonesia

   

Backend engineer based in Karawang, Indonesia, specializing in the design and development of reliable,
high-performance server-side systems. My work centers on API design, backend architecture,
and database optimization, with a consistent emphasis on clean and maintainable code.

I am open to professional collaboration and networking with engineers, teams, and organizations.
Please feel free to get in touch through any of the channels listed below.

	Area	Description
	API Design and Architecture	Contract-first API design with clear, consistent, and well-documented interfaces
	Server Engineering	High-performance, stateless services built with Node.js, Bun, and Go
	Database Design and Optimization	Schema design and query optimization with PostgreSQL, MySQL, and Redis
	Code Quality and Maintainability	Modular code organized around the single-responsibility principle
	Security and Reliability	Authentication, rate limiting, input validation, and deliberate error handling by default

	Category	Technologies
	Runtime and Language
	Framework
	Database and Cache
	DevOps and Tools

	Area	Details
	Building	Backend systems with NestJS, Go, and PostgreSQL, deployed with Docker on VPS infrastructure
	Studying	Go concurrency patterns and gRPC; PostgreSQL query optimization
	Exploring	Bun runtime internals and edge computing
	Performance target	p50 latency below 80 ms
	Reading	Clean Architecture by Robert C. Martin

	Principle	Approach
	Data-flow oriented design	Trace the complete data path, not only individual functions
	Stateless by default	Services designed to scale horizontally
	Latency as a requirement	Performance is treated as a first-class concern
	Single responsibility	Each module owns exactly one concern
	Secure by default	Authentication, rate limiting, and validation are standard practice
	Incremental delivery	Small, testable, and independently deployable units
	Contract-first APIs	API contracts are defined before implementation begins
	Graceful failure handling	Every error path is designed deliberately

"The best system is one you can explain in five minutes but that runs for five years."

 

I welcome opportunities to collaborate and to build lasting professional relationships.
Areas of particular interest include:

	Area	Description
	Backend and API projects	Design and development of backend systems and APIs
	Open-source contribution	Contributing to and collaborating on open-source projects
	Complex engineering problems	Performance, scalability, and system design challenges
	Professional networking	Exchanging ideas and experience with fellow engineers
