I help companies build reliable, high-performance C++ software — from multithreaded systems and performance optimization to AI-powered features that scale in production. I specialize in modern C++, system design, concurrency, Qt, networking, and performance-critical applications. I help teams solve complex engineering challenges such as improving application speed, designing robust architectures, debugging difficult issues, and building maintainable software. With 10+ years of software development experience, I have worked on challenging projects across desktop applications, embedded systems, cross-platform software, and backend technologies. My experience includes C++, Qt, Linux, Windows, macOS, gRPC, Protocol Buffers, multithreading, debugging, and optimization of complex systems. My approach: • Understand the business and technical problem before writing code • Design solutions that are reliable, maintainable, and scalable • Write clean, efficient C++ following modern best practices • Communicate clearly with regular updates and transparent progress I focus on delivering production-quality software, not just completing tasks. Whether you need performance improvements, a new C++ feature, architecture guidance, or help solving a difficult technical problem, I can help. If you have a challenging C++ project and need an experienced engineer who can work independently and deliver high-quality results, feel free to send me a message.

I am a Senior Software Engineer specializing in modern C++ (C++17/20) and R&D. I design and build high-performance, memory-efficient systems for companies that need speed, reliability, and scalable production code. With a Master's degree in computational mathematics and experience engineering solutions at the enterprise level, I bring strong analytical problem-solving to every project. My core focus: • Performance-critical C++ (multithreading, low-latency systems, memory management) • Custom algorithms & machine learning (probabilistic algorithms, fuzzy classification, inference optimization) • Desktop application development (Qt/QML) • Systems architecture & Linux environments What I can help you with: • Optimizing existing C++ codebases (CPU, memory, concurrency) • Porting ML models (Python to C++) for high-speed inference • Building backend systems for Linux/embedded environments • Developing advanced UI components and rendering stacks Tech stack: C++17/20, STL, multithreading, Qt/QML, CMake, Python, Linux/Ubuntu I prioritize clean architecture, measurable performance improvements, and clear communication. If your system needs to be faster, leaner, or more scalable, let's discuss how I can help.

I design, scale, and modernize AWS cloud infrastructure, SaaS platforms, and high-load Laravel/backend systems. With 11+ years of software engineering experience and a background as a Solution Architect, Technical Lead, and CTO, I help companies solve complex problems around scalability, performance, reliability, cloud infrastructure, database architecture, and system modernization. I work at both the architecture and implementation level. I can review an existing platform, identify bottlenecks and technical risks, design the target architecture, create a practical migration roadmap, and work directly with the engineering team to implement critical changes. My strongest areas include: Cloud & AWS Architecture - AWS solution and infrastructure architecture - EC2, ECS, Lambda, SQS, SNS - RDS / Aurora - ElastiCache / Redis - S3, CloudFront, Load Balancers - Serverless and event-driven architecture - Docker and containerized workloads - Terraform / Terragrunt - Full pipelines and CI/CD - Cloudflare - Infrastructure modernization and cloud migration Laravel & Backend Architecture Laravel has been one of my core technologies throughout my career, including large and complex production systems. I can help with: - Laravel architecture and senior backend development - High-load Laravel applications - Legacy Laravel modernization and refactoring - Laravel performance optimization - Database and query optimization - Redis caching strategies - Queue architecture and background processing - REST and GraphQL APIs - Complex third-party integrations - Modular monolith and microservices architecture - Laravel applications running on AWS I also work extensively with Node.js, NestJS, and TypeScript, particularly for modern SaaS platforms, APIs, microservices, and distributed backend systems. SaaS, Scalability & High-Load Systems I have worked with systems handling large databases, high traffic, complex asynchronous processing, and hundreds of thousands of users per day. Typical problems I help solve include: - Applications that have outgrown their original architecture - Slow databases and inefficient queries - Scaling API and backend workloads - Queue and worker bottlenecks - Redis and caching architecture - Infrastructure reliability issues - Risky or manual deployments - Monolith modernization - Microservices migration - Database scaling - Search architecture using Elasticsearch, Typesense, or Meilisearch - Designing systems that can scale without unnecessary rewrites Architecture Review & Technical Leadership I also work with founders, CTOs, and engineering teams on: - Solution architecture - System architecture - Software architecture - Technical architecture audits - Cloud architecture reviews - Performance and scalability audits - Infrastructure reviews - Migration planning - Technical roadmaps - Technical due diligence - Fractional CTO support - Engineering and architecture leadership I focus on practical architecture rather than architecture for its own sake. The goal is to choose solutions that fit the current business, team, traffic, budget, and expected growth. AI / LLM Architecture Where relevant, I also design and integrate AI-powered systems using: - OpenAI APIs - Claude - RAG - Vector databases - AI agents - LLM integrations - AI workflows and backend services My frontend experience includes Vue.js / Nuxt and React / Next.js, which allows me to understand the complete product architecture and lead end-to-end technical delivery when necessary. If you need a Cloud Architect, AWS Solution Architect, Solution Architect, System Architect, Senior Laravel Developer, Laravel Architect, Backend Architect, Technical Lead, or Fractional CTO who can both design the solution and work hands-on with the implementation, I can help
