I'm a results-driven Backend Developer specializing in Java, Go, and Python, currently working at Techolution Inc.. My work focuses on building high-performance, scalable systems leveraging Spring Boot, GCP, and event-driven architectures. I love solving complex backend problems, designing distributed systems, and automating workflows with cloud-native and AI-powered solutions.
- ๐ญ Currently developing cloud-native FinTech applications and AI-powered ingestion systems on Google Cloud Platform
- โ๏ธ Experienced with event-driven architecture (Pub/Sub, Kafka) and batch processing with Spring Batch
- ๐ฑ Learning advanced distributed systems design and LangGraph/LangChain-based AI pipelines
- ๐ฌ Ask me about Spring Boot, System Design, Event-Driven Systems, or GCP architecture
- โก Fun fact: I once optimized a data ingestion pipeline by 40% using concurrency and I/O tuning!
