Backend Engineer specializing in TypeScript, Nest.js, Kafka & MongoDB.
I help companies build robust, scalable, and secure backend solutions. With 4 years of experience in outsourcing and product environments, I’ve learned how to adapt quickly and deliver high-quality code under acceptable deadlines. Successfully delivered projects in FinTech, Conversation Intelligence, and AdTech industries. I am passionate about clean code, performance optimization, and solving complex architectural challenges.
Top Skills: Node.js, NestJS, Apache Kafka, Microservices, System Architecture.
🚀 Key Professional Highlights:
- Resolved critical race conditions between APIs and third-party webhooks by engineering a custom Kafka-based transport layer. Achieved 100% data consistency through strict partition key ordering.
- Led a comprehensive REST API audit and refactoring, optimizing database queries and resource-heavy endpoints. Successfully reduced latency by up to 12x, significantly enhancing system responsiveness.
- Designed and launched 8+ microservices from scratch using Nest.js and Kafka. Leveraged an event-driven approach to isolate complex business logic and ensure independent scaling of components under load.
- Architected a flexible admin ecosystem using Payload CMS, empowering non-technical stakeholders (game designers) to manage game balance and stores independently.
- Built a high-performance search engine using OpenSearch to index and filter thousands of transcripts, enabling instant full-text search and complex data aggregation.
- Developed a real-time incident notification system (Telegram API + Centralized Logging), significantly reducing MTTR and improving team response times to critical errors.
