Tirth Nisar

I am a software engineer who enjoys building systems that solve real-world problems at scale.

My interests lie at the intersection of backend engineering, financial infrastructure, and intelligent data processing systems. I enjoy designing APIs, working with distributed services, and building platforms that can reliably process large volumes of data.

Over the years I have worked across multiple areas of engineering including backend systems, AI-driven document processing, mobile applications, and data analytics. This breadth has helped me develop a strong understanding of how different parts of a technology stack interact in real production environments.

I am particularly interested in:

• Backend and distributed systems
• Fintech infrastructure and secure APIs
• Application Development with Flutter
• AI-assisted document processing (OCR + LLM workflows)
• Data processing pipelines and automation

Tech I frequently work with:

Python, FastAPI, NestJS, Flutter, Redis, PostgreSQL, AWS, Docker, Celery

I enjoy tackling complex engineering problems, improving system reliability, and building products that move from idea to production.

Always open to interesting technical conversations and challenging engineering problems.
