What I'm looking for

I seek remote roles building scalable ETL, backend, and ML‑enabled systems with strong engineering practices, collaborative Agile teams, and opportunities to work on data pipelines, automation, and cloud infrastructure.

I am a full‑stack data engineer and software developer focused on building scalable ETL pipelines, backend microservices, and reliable data extraction systems that drive analytics and product features. I combine backend engineering (Flask, Django, FastAPI), cloud infrastructures (AWS, Terraform), and automation (Scrapy, Playwright, Selenium) to deliver production‑ready solutions.

Across remote roles for startups and consultancies, I designed high‑performance ingestion and job retrieval APIs, built distributed scraping pipelines handling thousands of concurrent tasks, and improved observability and cost‑efficient deployments using serverless and Terraform patterns. I have also integrated ML and NLP (OpenAI, PyTorch) for classification, document summarization, and CV parsing to increase search relevance and automate metadata extraction.

I collaborate in Agile teams, contribute to architecture and sprint planning, and prioritize reliability, data quality, and low latency. I am currently pursuing an M.S. in Artificial Intelligence and Engineering Technology and continuously build projects that bridge OCR, computer vision, and semantic matching to solve real‑world problems.
