Himanshu Panwar — CEO

I am a result driven and customer centric software architect with 14+ years of experience in designing and building distributed, highly available, and low-latency systems across multiple domains. Currently working at a high growth SaaS company, I take ownership of complex projects with significant impact, including driving $3 million in annual cost savings by optimizing and automating core systems. I am responsible for managing high scale and ensuring seamless performance under high demand conditions. Throughout my career, I’ve not only focused on building high performance systems but also on mentoring junior engineers and fostering a collaborative, high performing team environment. I thrive in guiding teams through technical challenges, encouraging growth, and ensuring the seamless execution of complex projects. My previous experience spans building and optimizing data pipelines, microservices, and streaming architectures. I’ve contributed to high-growth environments, including a social media startup (similar to TikTok) with 190M+ MAUs, where I played a key role in scaling and enhancing both new and existing microservices. I have a solid background in Java, Spring Boot, JPA, REST API, and Python, and I’m well-versed in both relational and NoSQL databases such as MySQL, MongoDB, ScyllaDB, and Redis. Additionally, I have hands-on experience with RabbitMQ, Kafka, and cloud technologies like AWS. I have working knowledge of Go. I am also skilled in containerization and orchestration with Docker and Kubernetes, and have proficiency in monitoring tools such as Datadog, Splunk, New Relic, and Prometheus. I’m passionate about driving innovation through ownership, delivering robust solutions that meet business needs while ensuring high customer satisfaction, and fostering a supportive environment for junior developers to thrive.

Zero Touch Migration: Designed and implemented a comprehensive zero-touch migration microservice system that automates new customer platform transitions at scale to Capillary Core products from their old platform. The solution captures incoming requests, replays data replication on demand, and validates data integrity. Resulted in $3 million in annual cost savings by automating large-scale migrations and ensuring error-free data transfer for our clients.
Custom OAuth2.0 Implementation: Led the design and implementation of an OAuth 2.0 security stack in the core CRM product, enabling seamless integration of vendors of our clients to the core customer data and enhancing product security for customers. All the access to the data is controlled, tracked and audited through consent management.
Custom MySQL Proxy: Developed a custom MySQL proxy solution for sharded MySQL databases, for custom on demand queries for debugging. This improved data security, performance. Key features included:
Protection of PII (Personally Identifiable Information) through secure data routing. Handling long-running queries, limiting query results, and enabling detailed audit logging. Modified MySQL client-server protocols to route traffic to the appropriate database shard based on connection metadata (username/password). Managed traffic routing and ensure logging for security and performance optimization.
Team Leadership: Managed a team of 5 engineers, overseeing project delivery, mentoring, and fostering collaboration to achieve technical and business goals.

Post De-duplication Service:
◦ Redesigned post de-duplication microservices from scratch for Moj app (similar to TikTok)
and ShareChat that scales to 190M MAUs. New system can handle 60k req/s and processes more than 3B post view events/day. Redesigning resulted in reduction in system operating cost by 25% and latency by 9% on average
◦ Build data pipeline to efficiently store post view events for fast read access pattern. Simplified architecture by eliminating the need of caching (redis) at multiple levels, performed zero downtime migration of the compute, streaming jobs and terabytes of data in database from BigTable to ScyllaDB
◦ Brought transparency and simplicity to the data access that helped in performing A/B testing much more quickly and efficiently
◦ Standardised the REST APIs, unified codebases across the two products, and improved metrics logging and tracing which was non existent
◦ Build custom async data pipeline using pubsub, dataflow, that is used to collect and store application trace logs to BigQuery for analytics to overcome the limitation of existing tracing client library

As a part of the Document Classification As a Service, I work closely with product managers to define and drive the scope of the product in the Agile framework. Provide technical assessment about the feasibility of the feature
Responsible for developing and designing key features into highly available distributed RESTful services and microservices. These services serve around 2 million document processing requests a month.
Implemented asynchronous request-reply design pattern by introducing RabbitMQ in web service to improve the resilience of microservices
Improved text detection and localization accuracy on scanned text images by 8%,which in turn improved the accuracy of the OCR system
Worked majorly on high-level design (HLD), automated tests, code reviews, and DevOps approach
Led the initiative for containerizing applications to Docker which in turn reduced time to delivery by 80%. This eased the process of software delivery and building custom components based on requirements with the microservice architecture
As a part of infrastructure migration, migrated complete application infrastructure to Kubernetes with Gitlab CI/CD, resulting in lowering the infrastructure cost.
