Hi, I’m a Senior Backend Developer with 5+ years of experience, working primarily with Go (Golang) and Node.js, focused on building backend systems that are secure, scalable, and observable. I also have experience working on frontend applications and Devops tasks, and I’m comfortable working on cloud environments. Most of my work is around: - Payment processing such as Stripe, Stripe Auto Connect, PayPal, Airwallex and more. - Designing and building scalable and secure APIs (idempotency, retries, backoff, failure handling, request sanitization). - Implementing complex business logic, not only CRUD. - Make backend service observable by adding structured logging, metrics, and tracing. - Improve database query performance & indices tuning. Tech stack: - Backend: Go, Node.js (Express.js & Nest.js) - Frontend: React, Next.js, CSS - Database: PostgreSQL, Spanner, MongoDB, Elasticsearch - Message Broker: Kafka, RabbitMQ, Google PubSub - Others: Docker, Kubernetes, CI/CD What you can expect when working with me: - I like to clarify the requirements before proceeding to work on the task. - I like async work, but having a sync meeting is also fine. - I use AI to speed up my work and still maintain the quality by reviewing the output and validating it. - I have discipline to test, review and validate AI-generated code.
