About

Passionate about building scalable, high-performance backend systems with expertise in IoT platforms, real-time data pipelines, distributed systems, and event-driven architectures. With almost 8 years of experience, I have designed and developed microservices, metadata management systems, and firmware update solutions (FOTA) for large-scale applications. I specialize in Low-Level & High-Level Design (LLD, HLD), database optimization, and real-time processing using Java, GoLang, Python, and technologies like Kafka, gRPC, PostgreSQL, Redis, and TimeScaleDB. Always, excited about solving complex challenges in scalability, automation, and real-time data processing to build efficient and reliable systems.

Product: Metadata Visualization Service
Leading the development and POC to use a common data source for multiple backend metadata verticals, reducing the multiple
database usage.
Lead the Project of Warner Bros Rebranding to HBO MAX
Leading a cross-team project for Bleacher Reports by Making an Event Based Article Ingestion to Google and BING Search
Index
Refactored legacy codebase to reduce rebranding deployment time from 30 days to 2 days, achieving efficiency improvement of
93 percent.
Refactored legacy implementation of existing metadata delivery which reduced hash calculation and comparison and generating
status for each record (for almost 300K records) from almost 14 hours to 3 minutes.
Designed and implemented an event-driven messaging protocol to efficiently deliver metadata to clients.
Led the successful deployment of a unified metadata architecture for Discover+ and Max apps across the US and Canada,
reducing internal system data overhead by nearly 60
Transformed the legacy system into a SaaS-based platform with a unified metadata architecture for Discovery+ and Max OTT
apps, enabling both applications to share the same underlying schema and data pipeline. This significantly reduced data
redundancy and improved the maintainability of message channels, schemas, and formats.
Collaborating with cross-functional teams to streamline metadata-related workflows, unifying internal services, databases, and
data structures to improve system scalability and consistency.
Developing a Delta metadata generation framework tailored for partner-specific needs.
Refactored microservice architecture to adopt an event-driven model, ensuring real-time updates for partner-specific metadata
upon generation.
Built a configuration API service integrated with a user-friendly user interface, enabling operators to efficiently manage workflows
across multiple partners.

Built a Flink job for real-time data calculations received from IoT machines.
Developed a bidirectional data pipeline handling 10ms message frequency for nearly 200 machines running in parallel.
Created a Data Quality Service, processing camera data every 100ms and responding with real-time quality analysis within the next 100ms.
Developed machine simulation flows for Proof of Concept (PoC) in data pipeline testing.
Collaborated with the AMR (Autonomous Mobile Robot) team to integrate, manage, and control robotic devices deployed at manufacturing sites.
Built Python-based data pipelines connecting IoT systems, Redis, TimeScaleDB, and Grafana.
Product: FOTA (Firmware Over-the-Air Updates)
Led the FOTA Backend Team, overseeing design and development.
Developed a FOTA service that securely delivered software updates to 120,000+ electric scooters across MoveOS 2 & MoveOS 3 releases.
Proposed and implemented a fix for scooter overheating issues caused by incompatible software installations.
Designed and implemented a PULL-based FOTA system, where scooters initiate update requests to retrieve and install the correct firmware versions.
