I'm a backend-focused engineer with 5+ years of experience building and scaling production systems, primarily with Python, Django, Django REST Framework, and PostgreSQL.

I've worked across security data pipelines, logistics automation, microservices, asynchronous processing, and developer tooling—from building systems from scratch to refactoring and scaling existing applications.

🔐 Security Data Pipelines

At Crest Data, I work on data normalization and parser systems for security data pipelines, supporting threat-detection use cases.

I also designed and built a Config-Based Normalization (CBN) parser testing framework using Django and React, significantly accelerating parser validation and reducing validation errors.

🚚 Logistics Automation

Previously at Fero.ai, I built and led backend development for logistics automation products covering last-mile delivery and 3PL operations.

This included designing database schemas, building Django REST APIs, implementing asynchronous workflows with Celery and Redis, and developing reusable microservices.

🏗️ Engineering & Technical Leadership

I've also worked on:

• Refactoring legacy systems and reducing technical debt
• Designing reusable backend services and APIs
• Database and schema design
• Code reviews and architectural decisions
• Mentoring engineers
• Technical discussions with clients and stakeholders

• Backend architecture & system design
• Distributed and asynchronous systems
• Database design & performance
• Security engineering & data pipelines
• Developer tooling and automation
