Full-stack engineer who ships backend, owns cloud infra, and builds the hardware too.

6+ years in production - billing systems, payment pipelines, and real-time services at a telecom company, plus freelance work spanning AWS infrastructure, LLM/RAG integrations, and embedded devices on STM32 and ESP32.

Where I am strongest

Roles where the mix of production backend work, cloud ownership, AI integration, and hardware curiosity is useful.

Backend / Full-stack Engineer

Node.js, NestJS, APIs, databases, payments, portals, admin systems.

AI Integration Engineer

LLM APIs, embeddings, RAG, document ingestion, assistant workflows.

AWS / Product Owner Engineer

Terraform, AWS services, deployment flow, end-to-end product delivery.

IoT-aware Software Engineer

ESP32, STM32, Raspberry Pi, C/C++, devices, sensors, streaming.

What I build with

Mostly backend and cloud, with frontend when a project needs a sole full-stack owner - and a hardware layer most engineers don't touch.
