About Me
Experience
2+ YearsEfficiency
60% DB ReductionData Freshness
15 minResults-driven Python Backend Engineer with 2+ years of experience designing scalable backend systems, high-performance REST APIs, and automated data platforms. My work spans Flask, FastAPI, PostgreSQL, Apache Airflow, Odoo, and AWS services such as EC2, S3, Athena, Redshift, Lambda, and Secrets Manager. I focus on backend reliability, API security, cloud delivery, and turning operational problems into measurable engineering wins.

Pipeline Freshness
Re-architected batch workflows into incremental Airflow pipelines for executive BI dashboards.
FastAPI p95 Response
Tuned indexed query paths, schema validation, and async request flow for analytics APIs.
Observability Improvement
Added Airflow callbacks, SNS alerts, and more visible pipeline status for quicker incident response.

Engineering Focus
Secure API Design
I design backend services with JWT auth, OAuth 2.0, RBAC, rate limiting, clean validation, and explicit error contracts so APIs remain secure and easy to consume.
- Flask and FastAPI service design
- Token lifecycle and permission control
- Swagger/OpenAPI-ready endpoints
Data Pipelines That Operate Cleanly
I build ETL and ELT systems that support incremental sync, backfills, alerting, and analytics warehouse delivery without constant manual intervention.
- Airflow DAG orchestration and scheduling
- Athena, Redshift, and PostgreSQL movement
- SNS alerts and observable pipeline states
Cloud Delivery With Operational Discipline
I treat deployment and infrastructure as part of the product, using Docker, Jenkins, Nginx, SSL, and AWS services to ship backend systems with reliability in mind.
- EC2 deployment, HTTPS, and routing
- Containerized services and CI/CD pipelines
- Secrets handling and production readiness
