About

Professional summary

I am a Senior Software Engineer with more than 10 years of experience building enterprise-grade fintech, mobile banking, SaaS, and AI-powered systems.

I specialize in full-stack development across C#, .NET, Python, Django, FastAPI, React, Flutter, Java, and cloud-native microservices. I have delivered more than 15 enterprise applications serving millions of users.

I have led cross-functional engineering teams of up to eight engineers, consistently delivering critical projects on time while improving development practices, code review processes, and Agile delivery.

I build AI-integrated products using OpenAI APIs, GPT-4o, Whisper, Azure Cognitive Services, conversational AI platforms, and machine learning models for sentiment analysis and KPI prediction.

I have strong DevOps and cloud experience with AWS, Docker, CI/CD, GitHub Actions, Bitbucket, AWS Fargate, CloudFormation, monitoring, and infrastructure automation. My work has reduced deployment times, improved system reliability, and supported high-volume transaction platforms.

I am experienced in secure, scalable financial systems, including payment integrations, PCI-DSS-aligned applications, RBAC, OAuth 2.0, real-time WebSocket services, and multi-tenant architectures.
