Panchavaktra Advisory LLP (Startup)
Project Lead
- Led the design and development of multiple SaaS applications using MERN Stack, along with some of their mobile counterparts in Flutter, focused on scalability, client-specific customization, and successful production deployment, with several applications actively serving end-users.
- Designed and implemented scalable APIs and background workers for managing first- and third-party integration, verifying payments and heavy and large file processes using Node.js, Python, SQS, Lambda, and other AWS cloud technologies that serve thousands of requests daily. Enhanced system performance by designing efficient database schemas, implementing indexing, optimizing queries, and introducing caching strategies — resulting in a 20% improvement in data retrieval efficiency.
- Built a real-time distributed system leveraging WebSockets and Server Sent Events (SSE) to enable instant data transmission and event updates, reducing data latency by 30% and significantly improving the overall user experience.
- Developed an AI-powered assistant using the LangGraph framework, capable of querying databases via natural language, filling forms through an interactive UI, and providing actionable insights — boosting client productivity and saving operational time. Also built an invoice processing OCR and reconciliation agent.
- Led the development of several products E2E, from identifying system requirements and partner dependencies to workload balancing, software implementation, engineering, testing, and configuring metrics, alarms, monitors, and dashboards.
- Enriched system metrics by integrating the platforms with telemetry; facilitated in-depth logging by correlating APIs with vector contexts.
- Continuous Integration/Deployment Pipeline Integration, pull requests, code reviews, load/stress testing, unit/integration/e2e testing.
