Areas of focus

Domains & Expertise

Backend Development

Designing and shipping scalable, maintainable server-side applications with Django, DRF, and Python — from clean API contracts to complex business logic.

Caching & Performance

Implementing Redis-based caching strategies to dramatically reduce database load, cut response latency, and keep high-traffic systems responsive at scale.

Database Design

Architecting efficient relational and non-relational schemas in PostgreSQL, MySQL, and MongoDB — with a focus on indexing, query optimization, and data integrity.

Microservices

Decomposing monoliths into independently deployable services with clearly defined interfaces — enabling teams to ship faster without stepping on each other.

Serverless Architecture

Building event-driven, serverless pipelines on AWS (Lambda, ECS, SQS, Step Functions) to handle high-throughput workloads with automatic scaling and zero infrastructure management.

Amazon Web Services

Leveraging AWS services (EC2, S3, RDS, Lambda) to build resilient cloud infrastructure — balancing cost, performance, and operational simplicity.
