Language & Tools

Java, Python, AWS, Docker, Docker Compose, Apache Kafka, MongoDB, SQL, System Design, Distributed Systems, Clean Architecture.

Currently Exploring

Currently engineering 'My Broker B3,' a microservices-based financial brokerage simulator. I’m deep in the weeds with Kafka partitioning, database isolation strategies, and solving event-consistency challenges at scale. When I'm not pushing code, I’m rigorously optimizing my second brain (Obsidian + Git) and refining high-performance, distraction-free dev workflows.

Achievements

Tech Lead & Senior Software Engineer: Spearheading the design and delivery of resilient, distributed financial systems.

Merit-based advancement (2026): Recognized for architectural vision, mentorship, and driving technical standards within the team.

Architecting 'My Broker B3': Building a complex, event-driven trading ecosystem from the ground up to master microservices at scale.

Early Contributor at CoderLegion: Committed to fostering high-signal, pragmatic technical discourse.

Fun Fact

I run my home office like a production environment—if it's not optimized or automated, it doesn't exist. Proud owner of three cats that serve as my personal 'chaos monkeys', ensuring I never get too comfortable while debugging complex microservices.

Random Dev Quote

Complexity is free to create but expensive to maintain. Always optimize for the latter.

About: Senior Software Engineer & Tech Lead driven by the challenge of designing resilient, scalable microservices architectures. I believe that good engineering is intentional—complexity should be justified, and simplicity is the ultimate goal. I specialize in distributed systems, event-driven architectures (Kafka), and cloud infrastructure. Currently documenting my journey building a financial brokerage simulator from scratch. I'm always looking to connect with engineers who value clean architecture and pragmatic, high-impact solutions.
