Senior🎓
Top SchoolAlexey Haidamaka is a senior software engineer with 11 years of experience building resilient backend systems for SaaS and fintech, currently working as an independent contractor from Poznan, Poland. He has led architecture and core backend development across startups and enterprises, delivering billing and monetization platforms, trading and payment systems, and real-time replication tools using a polyglot stack (Python, Java/Jython, C#, Kubernetes, GCP). Alexey combines hands-on coding with system design and CI/CD improvements, having moved legacy services to modern containers and introduced test and deployment optimizations that materially sped delivery. He’s comfortable in both startup and corporate environments, driving cross-team collaboration and mentoring engineers while tackling fault-tolerant, high-throughput backends. A detail that stands out: he has repeatedly bridged languages and runtimes (Jython on JVM, .NET to .NET Core/Docker) to modernize legacy products without disrupting customers.
