What I'm looking for

I’m looking for a team where I can build scalable full-stack and AI-powered applications—owning backend performance, LLM/RAG features, and cloud-native DevOps—so we ship reliable products in a modern, engineering-focused culture.

I’m a fullstack developer with 6 years of experience building scalable web and AI-powered applications using Python (Django, FastAPI, Flask) and React.js. I focus on turning real product needs into reliable systems—especially where LLMs, semantic search, and automation deliver measurable impact.

At Addo AI (2023–Present), I developed scalable full-stack applications for AI-driven enterprise platforms and analytics systems. I built asynchronous backend services and REST APIs with Asyncio, Celery, Redis, and DRF, and integrated OpenAI API, LangChain, RAG pipelines, embeddings, Pinecone, and pgvector to create AI assistants and semantic search solutions.

I also bring cloud-native DevOps experience with Docker, Kubernetes, AWS, Terraform, and CI/CD pipelines, managing deployments for scalable and reliable production environments. Earlier roles strengthened my backend foundations and distributed workflows using Kafka, Airflow, and secure REST API development with Django REST Framework.
