Software Architect · Backend Engineer · iOS Developer
I design and build scalable software systems, from high-performance backend infrastructure and distributed services to native iOS applications and real-time platforms.
My primary focus is software architecture, system performance, concurrency, and long-term maintainability.
I enjoy solving complex engineering problems, exploring new technologies, and building tools that make software development more predictable and efficient.
- Software Architecture — distributed systems, microservices, event-driven architectures, and API design.
- Backend Engineering — high-performance services with Go and PHP, asynchronous processing, and real-time communication.
- iOS Development — Swift, UIKit, SwiftUI, custom UI frameworks, and concurrency.
- Data Engineering — relational databases, caching, high-volume event storage, and data processing.
- Infrastructure & DevOps — containerized environments, deployment pipelines, and service orchestration.
- Media Systems — video processing, transcoding, object storage, and media delivery.
- Game Technology — multiplayer backend architecture, networking, and Unity-based game systems.
| Area | Technologies |
|---|---|
| Languages | Go, PHP, Swift, TypeScript, JavaScript |
| Backend | Laravel, REST, gRPC, WebSockets, Microservices |
| iOS | UIKit, SwiftUI, Swift Concurrency, AsyncStream |
| Databases | PostgreSQL, Redis |
| Messaging | Kafka, Event-Driven Architecture |
| Infrastructure | Docker, Docker Compose, CI/CD |
| Storage & Media | S3, MinIO, FFmpeg |
| Game Development | Unity, Multiplayer Networking |
| Architecture | Distributed Systems, Clean Architecture, API Design |
Currently exploring: Temporal, RabbitMQ, ClickHouse, workflow orchestration, and large-scale event processing.
A lightweight reactive streams library for Swift, built around modern concurrency primitives.
- Native integration with Swift Concurrency and
AsyncStream - Reactive data flows and observable state
- Stream composition and subscription management
- Buffering and backpressure support
- Swift 6 strict concurrency support
- Zero external dependencies
I build open-source tools with an emphasis on simplicity, performance, and developer experience.
I'm particularly interested in the architecture and implementation of complex systems:
- Workflow engines — durable execution, event-driven automation, and long-running processes.
- High-volume data systems — event ingestion, storage optimization, indexing, and efficient queries.
- Real-time applications — messaging, streaming, network protocols, and asynchronous communication.
- Distributed infrastructure — reliable message delivery, fault tolerance, and horizontal scaling.
- Game systems — multiplayer networking, world architecture, and scalable backend services.
- Developer tooling — reusable libraries, abstractions, and infrastructure components.
I believe good software architecture should make complex systems easier to understand, operate, and evolve.
- Clarity over unnecessary abstraction
- Performance backed by measurement
- Simple interfaces, well-defined responsibilities
- Reliability and observability by design
- Maintainability over short-term convenience
- Choose technologies based on problems, not trends
I'm interested in challenging engineering problems, open-source collaboration, and discussions about software architecture, distributed systems, and developer tools.
