Professional Experience

Lead Backend Engineer / Full Stack Technical Lead (Promoted 3x: Intern → Full Stack Dev → Team Lead)

Zenmonk Software & Services (Subsidiary of FUNIBER)

June 2023 – Present

Resilient Messaging: Standardized organization-wide Resilient Message Handling using the Transactional Outbox/Inbox pattern, eliminating message drop across microservices.
ETL Pipeline Architecture: Architected a fault-tolerant Python ETL pipeline migrating entire organization's Asana history to Padmasana, using a dynamic thread pool and runtime token rotation to overcome strict API rate limits.
Recursive Ingestion: Engineered a two-pass recursive dependency ingestion algorithm for nested tasks, resolving parent-child hierarchies in bounded 10,000-record batches without foreign key violations.
Performance Optimization: Re-architected a blocking processing route on Question Management Bank into an asynchronous, chunked pipeline for 10,000+ files, reducing execution latency from 5 minutes to 15 seconds (95% reduction).
Multi-Tenancy & Security: Designed a multi-tenant isolation model with a multi-schema strategy on IBMS and built a dynamic, runtime-configurable RBAC engine.
Distributed Transactions: Implemented a database-level Saga pattern to orchestrate long-running, multi-step survey operations reliably without external coordinator overhead.
Data Security: Integrated client-side field-level encryption at the MongoDB layer to safeguard sensitive examination data independently of application code.

AI Pipeline: Constructed an asynchronous rendering pipeline connecting external generative video models with upstream CRM webhooks.
Analytics Scale: Designed analytics aggregation endpoints to track distribution and viewer engagement metrics at scale.

Selected Systems Projects

Layer-4 Load Balancer [Rust, Tokio, TCP/IP]: Asynchronous Layer-4 TCP reverse proxy and load balancer built in Rust (Tokio). Implemented Round-Robin and IP-Hash scheduling algorithms for high-concurrency stream routing and connection pooling. Source
Redis Lite [Rust, RESP, Concurrency]: Multi-threaded, in-memory key-value store adhering to the Redis Serialization Protocol (RESP). Built low-level TCP byte-stream parsing with atomic primitives for thread-safe concurrent reads and writes. Source
