SUMMARY

I'm a fullstack developer with 5 years of experience working on outsourcing and outstaffing projects in fintech, foodtech, and e-commerce.
I worked on complex projects involving legacy code, optimizing page loading speed and database queries. I developed a payment logic
service from scratch, enabling the company to deliver new payment features twice as fast.
I’m a proactive and communicative developer who bridges tech and business. I explain complex ideas simply, make balanced decisions,
mentor juniors, and stay active in continuous learning and tech communities.
