Golang Developer

RBTEX Exchange

• Designed and implemented 14 microservices for core components like order matching, wallet operations, and compliance.

• Used gRPC for efficient, strongly typed inter-service communication.

• Set up Kong as a gRPC-to-HTTP gateway for frontend and third-party integration.

• Employed Redis for caching to boost response time and reduce DB load.

• Integrated RabbitMQ and Kafka for asynchronous communication and event-driven architecture.

• Deployed and orchestrated services using Amazon ECS for scalability and resilience.

Bahamut Scanner

• Developed four microservices: Execution Parser, Data Normalizer, Frontend API, and Aggregator API.

• Built gRPC-based data pipelines between Execution Parser and Data Normalizer.

• Stored normalized data in PostgreSQL; optimized queries using indexing and execution plan analysis.

• Created RESTful APIs using Echo framework for frontend consumption.

• Deployed system via Kubernetes for high availability and scalability.

Bahamut Chain

• Contributed to a Golang-based Ethereum fork for both execution and consensus layers.

• Implemented POSA consensus algorithm combining stake and on-chain activity metrics.

• Added new fields (activity, deployer) in state and smart contracts.

• Enhanced proposer selection algorithm to factor in both stake and validator activity.

• Maintained compatibility with Ethereum P2P networking, finalization, and validation layers.

Sportsbook

• Built Golang microservice to deliver real-time event and coefficient updates to frontend via WebSockets.

• Consumed data from RabbitMQ and PostgreSQL.

• Developed high-level RabbitMQ library with configuration file support.

• Designed and implemented a custom query language to convert frontend JSON to SQL.

• Utilized Goroutines, Mutexes, Semaphores, Worker Pools, and Wait Groups for concurrency control.

Real Time Bidding

• Developed a service allowing users to register and set real-time bid prices.

• Supported real-time price updates and bidding logic.

Email Validation

• Implemented API endpoint using Gorilla Mux to receive email lists.

• Built universal email validation logic compatible with various providers.

• Published validation results to RabbitMQ.

XML Parsing

• Parsed XML files and transformed data into JSON and HTML formats.

• Used Regexp and REST APIs for data manipulation and delivery.

Quantum Computing

• Led quantum computing research and development team.

• Worked on quantum algorithms in cryptography and pharmaceutical domains.

• Represented the team to external companies.

Cownet

• Developed two Golang services and one C-based service for networked communication.

• Enabled inter-service communication via REST API and TCP sockets.

• Used MongoDB as the database backend.

• Implemented protocol-level integration with Gorilla Mux and custom networking logic.
