Senior Fullstack .NET Developer building scalable microservices and real-time data platforms.
What I'm looking for
I’m a Senior Fullstack .NET Developer with 6+ years of experience, including Lead .NET Engineer work, building scalable microservices and data-intensive backend systems.
I’ve developed a centralized backend platform for oil field modeling and real-time forecasting, enabling engineering calculations and decision-making through simulation model access and domain data versioning. I’m a core contributor to oil field modeling platform integration with Petex and tNavigator, improving critical system execution performance by 6x (30s → 5s).
I bring strong enterprise architecture skills across REST APIs and distributed systems, with experience in event-driven architecture using Kafka and RabbitMQ. I’ve built Azure-ready solutions, optimized performance-critical operations with EF Core and raw SQL, and implemented background processing with Hangfire for retries and scheduling.
On the fullstack side, I deliver end-to-end features using Vue 3 (Composition API) with .NET 8, integrating external services and APIs. I also lead through engineering rigor—code reviews, mentoring, SOLID/Clean Code practices—and collaborate across distributed Agile teams (US, EU, India).
