Professional Experience

Signature Achievements

• Designed and built scalable backend services and microservices using Python/FastAPI and PostgreSQL, handling high workloads and multi-tenant environments.
• Built and deployed async workflow systems using Celery, RabbitMQ, and MQTT for real-time provisioning, synchronization, and event-driven processing.
• Developed and delivered API-driven platforms with clean domain models, API versioning, and integrations with external payment, ERP, and IoT systems.
• Set up and maintained Kubernetes deployments with separate API, worker and scheduler services across multiple client platforms.
• Built CI/CD pipelines and automated release workflows using GitHub Actions and GitLab CI, ensuring reproducible deployments across all projects.
• Implemented observability from day one: distributed tracing with OpenTelemetry, metrics with Prometheus/Grafana, alerting, and error tracking with Sentry.
• Integrated Stripe and Mollie payment and invoicing flows, including VAT handling, in reliable idempotent backend services.
• Designed and implemented production AI systems using LLMs, RAG, vector search and agentic workflows across QuotCraft, Hiork, Midbel and VoltMol. The implementations include custom framework-free agents and LangChain-based solutions.
