About The Engineer

Who Am I

Profile Overview

I am a Backend-Heavy Software Engineer dedicated to architecting resilient, scalable solutions for complex business needs - from payment pipelines and queue-driven APIs to self-hosted infrastructure that stays reliable under real traffic.

Rather than being limited to a single domain, my core strength lies in rapidly adapting to diverse technical environments and translating abstract business requirements into robust system architectures. Whether it's optimizing database queries, orchestrating containerized infrastructure, or building secure APIs, my focus is always on delivering high-performance, maintainable software from the ground up.

What I Ship

  • Fintech & payment systems - wallet ledgers, webhook reconciliation, idempotent money flows, and admin tooling for live ops.

  • Infrastructure-heavy backends - on-demand Docker workloads, registry-based deployments, reverse proxies, and self-hosted VPS stacks via Coolify.

  • Full-stack product delivery - REST APIs, admin dashboards, Telegram bots, Mini Apps, and client-facing apps built to ship and stay maintainable.

Education

Finalizing my B.Sc. in Communication and Computer Engineering. Grounded in systems thinking - algorithms, network protocols, and low-level behavior - so what I ship stays fast and reliable under real load.
