About Me

Hi, I am Kuldeep Singh, a Software Engineer who builds scalable backend systems, payment infrastructure, and distributed services. I focus on reliable, production-grade code and systems that handle scale.

I have hands-on experience working with Golang, PostgreSQL, Redis, and microservice architectures. I’ve built transaction systems, reconciliation flows, bulk payment processing, and secure bank integrations handling thousands of daily transactions.

Currently, I am working at Unplex — a conversational payment and automation platform — where I’m designing backend workflows, AI-driven interactions, and system integrations to simplify business payments and communication.

I completed my B.Tech in Computer Science and continue to deepen my knowledge in system design, distributed architecture, and AI-integrated platforms. I’m always open to opportunities where I can build impactful products and grow with strong engineering teams.
