What I'm looking for

I am looking for a Backend / AI / Full Stack Engineer role in startup company.

I am a Senior Backend Engineer with over 7 years of experience in engineering scalable backend systems. My expertise lies in AI-driven solutions, consultancy, and API integrations. I have a proven ability to create end-user products in fast-paced environments through effective system design and optimization. Notably, I successfully launched 10 products that contributed over $200,000 in revenue.

In my recent role at Supercog.ai, I optimized the Text-to-Speech model, BARK, achieving a significant reduction in bot response time to 1.5 seconds, enhancing user experience. I architected CI/CD pipelines with AWS EC2 and Kubernetes, automating code deployment and streamlining procedures. My experience also includes developing high-performance data pipelines and integrating various tools to deliver actionable insights.

Previously, I revolutionized the intranet at Haystack, focusing on seamless integrations and powerful search capabilities. I spearheaded the development of a trading bot using advanced machine learning techniques, achieving accurate time series predictions. My work has consistently resulted in increased user retention and positive feedback, showcasing my commitment to delivering high-quality solutions.
