What I'm looking for

I am looking for a role that fosters innovation and collaboration, where I can leverage my technical leadership skills to drive impactful projects and support team growth.

I am a results-driven Tech Lead with over 8 years of experience in full-stack software engineering and DevOps. My career has been marked by a proven track record in designing and delivering scalable enterprise ERP, finance, and SaaS solutions, generating over $10M in revenue. I specialize in scalable system architecture, RESTful API design, and cloud platforms such as AWS and GCP. My commitment to aligning technology strategies with business objectives has led to a 30% increase in team productivity and successful leadership of cross-functional teams of up to 10 engineers.

In my current role at Nomalytica, I lead a cross-functional team of engineers and data scientists to develop AI-driven analytics platforms. I have successfully implemented Agile methodologies and established CI/CD pipelines, significantly reducing delivery times. My previous experience as a Senior Full Stack Engineer at GalaxyCoin.finance involved leading the development of core DeFi features and conducting security audits, which improved contract safety and reduced gas fees. I am passionate about mentoring junior engineers and fostering a culture of continuous improvement.
