What I'm looking for

I’m looking for a fast-paced, collaborative team where I can build secure, scalable products—optimizing performance, modernizing architecture, and shipping reliable features that measurably improve user outcomes.

I’m a Senior Software Engineer focused on building scalable web and mobile applications for fintech, healthcare, e-commerce, and software agencies. I bring hands-on experience across JavaScript, TypeScript, Python, and Java, and I specialize in React/Next.js, Node.js, Django/FastAPI, GraphQL, and real-time systems—grounded in delivering high-performance, user-centric results.

In recent roles, I integrated LLMs into product workflows (driving a 40% improvement in user query relevance), refactored services into serverless event-driven architectures to handle 3x peak traffic with lower costs, and built real-time Kafka-based pipelines to synchronize transactions across global regions in milliseconds. I also modernized deployment with mandatory security scanning and cryptographic signing, and improved user experience by migrating to edge-rendered Next.js and optimizing rendering performance to reduce LCP and boost conversions.
