Backend Engineer → Product Thinker | I build systems that scale & features users actually need

About

I started as a backend developer, focused on building systems that work. But I quickly realized: Good systems aren’t enough — they need to solve the right problems. That shift pushed me beyond code. Today, I work at the intersection of: • Backend Engineering (Java, Spring Boot, APIs, SQL) • Product Thinking (user flows, metrics, business impact) At ION Group: – Built and scaled backend systems for real-time data processing – Improved analytics performance by 40% through query optimization – Worked closely with product, design, and business teams to translate requirements into scalable solutions Previously: – Built data pipelines and dashboards that influenced product decisions – Used data to identify patterns and drive operational improvements I’m particularly interested in: → How backend systems impact user experience → Building data-driven products → Leveraging AI to improve product journeys (currently working on a GenAI chatbot) I bring a combination of: Technical depth + Product thinking + Business understanding Currently open to Backend / Product-focused roles. Let’s connect 🤝
