Work History
Software Engineer L1
5DataInc
01.2025 - Current
- Reduced API response time by 95% and eliminated redundant DB calls through query optimization and Redis caching, contributing to a 50% improvement in platform engagement, while mentoring three junior engineers, enforcing over 100 code reviews, and cutting deployment errors by 40% and bug count by 60% through automated testing and CI best practices.
- Architected a pipeline using AWS S3 for large-scale JSON storage and Amazon RDS for retrieval, combined with PostgreSQL materialized views to pre-aggregate 500,000+ records—eliminating query-time computation and improving analytics performance significantly.
- Designed the asynchronous task layer using Celery delay for long-running operations with real-time status polling and Celery Beat for scheduled periodic automation, reducing ETL pipeline times by 30% and cutting integration bug count by 60% through automated test coverage.
- Built a robust data integrity layer: used Django signals to decouple 10+ side-effect functions, implemented soft-delete patterns across 10+ modules to retire stale records without data loss, and designed a full audit log system capturing every mutation with a timestamp and author for compliance and debugging.
- Eliminated redundant database calls by implementing Redis caching for static reference data and in-memory dict initialization for dynamic hot data, choosing each strategy based on data volatility to maximize cache hit rate and minimize query load.
- Authored PL/pgSQL stored procedures to push complex business calculations into the database layer, reducing application-side processing overhead and keeping business logic close to the data—chosen over ORM-layer computation due to the volume and complexity of aggregations involved.
- Built two automation pipelines: a third-party-certified API integration to replace manual master data creation workflows and an AI-assisted document parsing screen (GitHub Copilot) to extract and persist structured data from multi-language evidence files, regardless of source format.
Backend Engineer
5DataInc
06.2023 - 12.2024
- Architected and maintained 20+ production-grade REST APIs on a microservices infrastructure, processing 500,000+ daily requests, consistently delivering 99.9% uptime across critical business operations.
- Engineered asynchronous data processing pipelines using Celery and Redis caching, cutting ETL runtimes by 30% and improving overall system performance by 20%—optimizations identified through cross-functional collaboration with product and data teams.
- Optimized database query performance using select_related, prefetch_related, and only() to fetch minimal required fields; enforced read-only field indexing to eliminate write overhead; and built a centralized utility layer of 20+ shared functions—reducing code redundancy and cutting unnecessary DB calls across the codebase.
- Implemented a Kafka consumer service for bulk data ingestion across microservices—chosen over synchronous API calls to decouple producers from consumers and handle traffic spikes without blocking the main request thread.
- Delivered end-to-end data workflows: integrated Pandas DataFrames for structured Excel report generation and used Django fixtures to reliably promote master data changes across staging and production environments, ensuring a consistent state at every deployment.
Junior Software Engineer
KloudPortal
10.2021 - 05.2023
- Engineered 8+ production web applications in Django/Python with PostgreSQL, and established an automated testing framework from scratch that raised backend code coverage from 65% to 90%, reducing regression defects, and enabling faster, more confident releases.
- Led code quality initiatives across the engineering team — conducted 100+ peer reviews, and introduced standardized best practices for readable, maintainable code, directly contributing to a 25% reduction in average page load times through disciplined, performance-focused reviews.
- Designed performant API response contracts using serializers to minimize over-fetching, and implemented lazy loading for large dataset pagination, resolving memory overflow issues during bulk extraction and establishing patterns later adopted at scale in subsequent roles.
- Consistently delivered client-ready features two or more weeks ahead of schedule across multiple sprints, mentoring teammates on task prioritization and Agile practices, establishing a delivery discipline that carried into team leadership responsibilities at 5DataInc.
