What I'm looking for

I seek hands‑on roles building secure, full‑stack applications or ML/NLP systems in collaborative teams that value security, performance, and continuous learning.

I am a full‑stack software engineer focused on building secure, scalable web applications using Java, Spring Boot, Angular, and modern backend practices.

I designed and implemented a secure banking platform with JWT, 2FA, role management, real‑time alerts, and an NLP chatbot, and I built production CRM and hospital management systems for real users.

My internships and freelance work improved API performance, database efficiency, inventory accuracy, and system availability through query tuning, caching, and optimized architectures.

I blend backend engineering, frontend frameworks, and data/NLP knowledge to deliver usable, secure systems and continuously learn through certifications in machine learning, NLP, and full‑stack development.
