With over 17 years of experience architecting enterprise-grade solutions across fintech, banking, and cloud-based infrastructures, I thrive on turning intricate challenges into streamlined, future-proof products. From leading full-stack development teams to pioneering automation and AI-driven innovations, I have a proven track record of driving technical excellence at scale. Whether it's optimizing high-availability transaction systems or engineering cutting-edge applications, my focus is clear: build technology that empowers, innovates, and endures. Recently, I’ve expanded my expertise into the field of Generative AI, Prompt Engineering, and GPT-based application development — integrating powerful LLMs like GPT-4 into modern web applications to create intelligent, automated, and context-aware user experiences. My skills are not limited to the following areas and languages ​​and I am learning the edges of knowledge every day. WHY CHOOSE ME AS A FREELANCER ? ✅ Enterprise-Grade Expertise – Proven experience in high-transaction, real-time, and secure systems for financial institutions, banking, and fintech. ✅ Full-Stack Mastery – Capable of handling everything from backend architecture to front-end UI/UX with cutting-edge technologies. ✅ LLM-Enhanced Development – Ability to integrate GPT-4 and OpenAI API into real-world SaaS platforms using tools like LangChain, FastAPI, .NET, and React. ✅ Efficiency & Speed – Rapid delivery of high-quality code while maintaining scalability and security. ✅ Agile & Collaborative – Smooth integration with existing teams, following Agile and DevOps best practices. ✅ Problem-Solving Mindset – I don’t just code; I create solutions that optimize business workflows and drive efficiency. ✅ End-to-End Support – From architecture and development to testing, deployment, and maintenance, I ensure a seamless process.
