What I'm looking for

I’m looking for a senior role where I can build secure full-stack systems and production AI (LLMs, RAG, agentic automation), focusing on performance, reliability, and clean architecture—ideally with a collaborative, fully remote global team.

I’m a Senior Full Stack Developer and software engineer with 9+ years of experience designing and delivering scalable backend, full-stack, AI/ML, and data-driven applications. I focus on secure, high-quality software that performs reliably for real users.

In my recent work, I build AI-powered solutions with Large Language Models using LangChain, OpenAI, and agentic AI frameworks. I’ve implemented RAG workflows to integrate LLMs with enterprise data and delivered AI agents for task orchestration, tool calling, and multi-step workflow automation.

I also engineer production-grade data and cloud pipelines—developing ETL/ELT workflows on Databricks and Apache Spark, integrating multiple data sources, and ensuring data quality, reliability, and efficient processing. Alongside this, I optimize backend performance through caching, asynchronous processing, and distributed architecture.

Across projects, I develop RESTful APIs and responsive UIs with React, and I support smooth delivery with Docker, Kubernetes, GitHub Actions, AWS, and GCP. I’m passionate about clean architecture, collaboration in Agile environments, and fully remote work with global teams.
