Head of Engineering

01 .NET / C# - deep expertise .NET 8.0, ASP.NET Core, Entity Framework Core. Clean Architecture / DDD. Multi-database experience: MySQL, Redis, MongoDB. This is the primary backend and you'll live in it. 02 Distributed systems Managing multiple independently deployed services in production. API gateway patterns, event streaming (Redis Streams), retry strategies, service orchestration. You've dealt with cascading failures and data consistency across services - not just in tutorials. 03 DevOps & infrastructure Linux VPS administration, CI/CD pipeline management (GitHub Actions), systemd services. Comfortable with current bare-metal setup but capable of planning container/K8s migration when scale demands it. 04 API integration management We have 25+ third-party integrations (Apify, EmailBison, Instantly, Short.io, etc.). You understand rate limits, retry strategies, and failover across enrichment providers. When a provider goes down, the system degrades gracefully. 05 AI/LLM integration Multi-model orchestration in production. Prompt engineering at a systems level - not chatbot prompts, but batch processing pipelines that qualify and personalize across hundreds of thousands of prospects. Cost optimization across LLM providers. 06 Database administration Production MySQL management at scale (60+ tables, bulk writes). Redis operations (cache invalidation, Stream consumer management, memory monitoring). MongoDB administration (aggregation pipelines, event storage). Query performance tuning is a recurring part of the job. 07 Monitoring & observability Setting up centralized logging, APM, alerting, and uptime monitoring. You know how to set up alerts that catch problems before they become incidents.
