Summary

Senior Software Engineer with ~9 years of experience designing and delivering scalable microservices and event-driven systems using Golang, Python, Kafka, and Kubernetes. Currently driving core development at DataNova, contributing to both fintech (Vestearn) and healthcare (AlaanMed) platforms by building modular, high-performance services with Golang, Django, and technologies such as gRPC, PostgreSQL, Redis, RabbitMQ, and OPA for fine-grained access control.

Previously led backend architecture for a production-grade sports streaming platform (Esfandiyar) utilizing RTMP, HLS, GraphQL WebSocket, and adaptive bitrate streaming. Demonstrated expertise in system performance optimization, distributed tracing with OpenTelemetry, CI/CD automation, and real-time data pipelines across complex distributed environments.

Work Experience
  • •Designed and delivered 8 production-grade, reusable microservices—Wallet, Payment, Reaction, GraphQL Gateway, Multi-Confirmation, Price Collector, Pricelist, and OPA Access—in Golang and Python, deployed across two cross-functional platforms. Leveraged Kafka and RabbitMQ for scalable, event-driven communication.
  • •Engineered a secure Wallet service for Vestearn, featuring ksqlDB for real-time stream processing, Redis-based distributed locking, and gRPC with TLS. Ensured idempotent transaction handling and event-sourced balance computation, achieving zero duplication across distributed systems.
  • •Implemented a centralized GraphQL Gateway, integrating multiple gRPC-based microservices with OPA (Open Policy Agent) for dynamic, attribute-based access control. This reduced unauthorized access incidents by 40%, enhancing compliance and security posture.
  • •Enabled full-stack observability by instrumenting OpenTelemetry (OTEL) tracing across core services—gRPC, Kafka, and RabbitMQ—improving root cause analysis and reducing MTTR (Mean Time to Resolution) by 25%.
  • •Enhanced search capabilities for AlaanMed’s Django-based platform using PostgreSQL, Redis, RabbitMQ, and gRPC. Delivered a weighted full-text search engine using tsvector/tsquery with fuzzy match support, enabling typo-tolerant, ranked multi-field queries without introducing Elasticsearch, reducing infrastructure overhead and simplifying maintenance.
  • •Built a high-availability CGNAT system that chewed through 160 GB of NAT packets without breaking a sweat, delivering uninterrupted performance at peak loads.
  • •Tuned session management algorithms to shave latency by 20%, making the system leaner and faster.
  • •Rolled out a bulletproof RBAC framework, tightening client access and slashing security incidents by 15%.
  • •Engineered a messaging powerhouse with NATS and Event-Driven Architecture, processing 1,000+ messages per second with a 40% performance leap.
  • •Mentored junior engineers to a 25% productivity spike, turning a team of learners into a squad of innovators.
  • •Stepped up as Development Tech Lead, delivering scalable architectures with a 99.9% uptime that kept critical projects humming.
