Services
I help teams design, secure, and scale backend systems that are robust, observable, and maintainable. My focus is exclusively on backend and infrastructure engineering. I work with companies that value clarity, autonomy, and clean architecture.

馃攼 Security Audits & Architecture Reviews
I perform deep technical reviews of your backend stack: authentication, RBAC, token handling, database-level access control (RLS), and DevSecOps posture. I help you build secure-by-default APIs and spot design flaws before they reach production.
Keywords: Go 路 PostgreSQL 路 REST/gRPC 路 JWT 路 mTLS 路 Zero Trust 路 GitLab CI/CD 路 RLS
鈿欙笍 Backend Development & Automation
I build backend services from scratch or improve existing architectures. Whether it鈥檚 a single-page backend or a distributed system, I deliver tested, observable, and CI-integrated code with long-term maintainability in mind.
Keywords: Go 路 PostgreSQL 路 Redis 路 RabbitMQ 路 Redpanda 路 Docker 路 Kubernetes 路 Argo CD 路 GitLab CI/CD 路 Terraform 路 Make
馃攷 Protocol Reverse Engineering & DPI
I reverse engineer undocumented or proprietary network protocols to understand, document, secure, or replicate their behavior. I use packet inspection, binary analysis, and network tooling to support system integration or custom middleware.
Keywords: Wireshark 路 gopacket 路 tcpdump 路 Protobuf 路 TLS 路 raw sockets 路 custom binary protocols
馃摗 Observability & Performance Engineering
I help you understand how your systems behave in production through logging, metrics, tracing, and alerting. I set up observability with minimal overhead and maximum impact, using open standards like OpenTelemetry.
Keywords: Prometheus 路 Grafana 路 Jaeger 路 OpenTelemetry 路 InfluxDB 路 Alloy, Elasticsearch, Kibana
馃Л Technical Leadership & Mentoring
I work alongside engineering leads and founders to bring structure and perspective to backend decision-making. From ad-hoc reviews to long-term support, I help clarify goals, challenge assumptions, and empower your team with clean patterns and clear docs.
Formats: async audits, short-term missions, or ongoing tech advisory
