Senior Backend Engineer

Over the past 7+ years, I have specialized in building highly scalable, distributed backend architectures. My primary focus revolves around Python, Django, and FastAPI.

Architected event-driven systems and microservices using AWS Lambda.
Engineered highly available database schemas utilizing PostgreSQL and Snowflake, managing platforms optimized for heavy concurrency.
Implemented Redis-based caching and rate-limiting to significantly reduce latency.
Maintained robust CI/CD pipelines and containerized applications with Docker.

@greatbackend

I am actively developing a technical education brand called @greatbackend. The project focuses on creating high-quality, professional infographics and tutorials to break down complex backend concepts (like API preflight calls and database indexing) for developers.

Scalable Multi-Role Platforms

A recent architectural focus has been designing hyper-scalable database schemas capable of handling a billion users. This involves complex permission-based features segregating user, author, and publisher roles efficiently.

Currently Exploring

I am currently diving deep into advanced System Design concepts to prepare for high-level backend engineering challenges. Alongside this, I am actively learning Rust—specifically mastering memory safety, variable mutability, and scope—to expand my toolkit for building ultra-performant systems.
