Clients work with me when they need someone who understands both engineering depth and business impact and can design systems that scale, stay stable and reduce operational overhead. I’m a Solutions Architect, Data Engineer and Backend Developer with 14+ years of experience building scalable data platforms and production grade backend systems for Ecommerce, Fintech, SaaS and Healthcare companies. I help businesses solve complex data and backend problems by designing systems that are reliable, secure and built for real world scale. From data ingestion to APIs and cloud deployment, I focus on clean architecture, automation and long term maintainability rather than quick fixes. My core expertise covers end-to-end data pipelines, backend services and cloud infrastructure using Python, Java, SQL and modern cloud platforms. I design ETL workflows, APIs and distributed systems that handle high volume data, background processing and integrations with confidence. On the data side, I build automated pipelines that extract, clean, validate and deliver analytics-ready data to warehouses, dashboards and APIs. On the backend side, I design API first systems, microservices and integrations that power products reliably under load. What I work on: • Data Engineering & ETL Pipelines (Python, Pandas, PySpark, SQL) • Backend Development & APIs (Python, Java, FastAPI, Django, Flask) • Cloud Architecture & Deployments (AWS, GCP, Azure) • Data Warehousing & Analytics (Redshift, BigQuery, Snowflake) • Workflow Orchestration & Automation (Apache Airflow) • Web Scraping & Data Extraction (Scrapy, Selenium, APIs) • Distributed Systems, Async Processing & Messaging • Database Design & Performance Optimization • Docker, Kubernetes, CI/CD and production deployments If you’re looking for a senior engineer who can own data pipelines, backend architecture and cloud infrastructure end to end, let’s talk.
