Software Engineer Kentagious Kollective LLC (Houston, TX) June 2025 – Present

• Designed and maintained relational database architecture for a SaaS platform, structuring schemas and writing optimized SQL query logic to expose clean, queryable data to dashboards and analytics layers serving 10K+ active users.

• Led a large-scale data migration, restructuring legacy schemas and executing transactional SQL scripts to convert and persist 10K+ records with validation checks ensuring data integrity and zero data loss.

• Built admin-facing analytics dashboards transforming raw operational data into actionable insights on system usage, user behavior, and business KPIs for stakeholders and decision-makers.

Software Engineer Savanti LLC (Miami, FL) Sept 2024 – May 2025

• Architected MongoDB schemas and built Python microservices on Azure (Functions, Blob Storage) to collect, manage, and convert raw market data into structured, queryable formats for data scientists and business analysts.

• Implemented data quality frameworks with AI-driven anomaly detection to enhance data reliability, flagging schema violations and inconsistencies before ingestion into downstream analytics and ML training pipelines.

• Engineered high-throughput data pipelines ingesting 1M+ records/minute from external APIs with optimized batching and concurrency, feeding preprocessed data into ML model workflows via automated n8n ETL orchestration. Software Engineer Warble Solutions (Ahmedabad, India) Aug 2021 – Aug 2023

• Led a team of five engineers to scale Node.js APIs for e-commerce systems serving 100K+ daily users, integrating ML model outputs into production to power personalized search and recommendation features.

• Built resilient ETL workflows using Apache NiFi to convert unstructured NoSQL datasets into structured analytical assets on AWS S3, simplifying downstream data processing and reporting pipelines.

• Architected automated data migrations from on-premise databases to AWS (S3, DataSync), designing cloud database architecture and building data quality monitoring alerts with Prometheus and Grafana. Software Development Intern Rhad Agency (Ahmedabad, India) Jan 2019 – July 2021

• Built full-stack e-commerce features (React, Node.js) with real-time dashboards converting raw transactional data into visual operational insights, and wrote advanced SQL queries exposed through FastAPI endpoints.

• Developed modular PHP APIs for backend data operations including authentication, cart management, and checkout, increasing code reuse and reducing data duplication across services.
