Writing robust microservices for the next generation EV charging ecosystem with full functional programming approach.

Enhanced a core notifications service for the Nord products like NordVPN via multiple channels - Wrote a bucket-priority based solution for Kafka producers and consumers - Migrated the microservice from custom infra to Kubernetes

Creating different components for a new age insurance backend stack.

Designed, developed a micro-service serving product & cost catalogs. (Golang, Docker, AWS S3, SQS, AWS step functions, Aurora Managed PostgreSQL, ECS, Kafka, Cassandra) Evaluated SQL and NoSQL databases for the data model and full text search capabilities. Developed auxiliary services and clients to consume the micro-service using Golang as well. 10+ million products, multicurrency costs from multiple vendors, 99.95% availability, high fault tolerance and resilience.

Designed,developed back-end services and features for a central server which manages edge-routers in VoIP infrastructure. Wrote services in Java (Spring), Golang, Python.

- Developed On device microservices in Java (Spring) and backend APIs in Java, Golang for data collaboration. - Developed Kubernetes PV drivers for storage volume arrays - Evaluated Kafka connector streams for data stores. - Designed NoSQL data models for Cassandra. - Implemented a Python-based CLI for storage array management. - Developed volume management layer for a distributed NVMe SSD storage array.

• Explored Libraries Harfbuzz, Skia(2D Graphics), FreeType, Open GL, Hwui(Graphics) and Android Runtime library for vari- ous rendering, cache performance issues. • Fixed support for many MEA, SEA languages rendering, their Uniocde/Uniscribe Rules Enabled, tested smart font technolo- gies such as CFF, Graphite(SIL) in Android. • Integrated, tested and explored GLyphy (Text Rasterizer OpenGL ES shader technology) for high-quality text rendering.
