Data platforms
Ingestion, orchestration and medallion pipelines designed for traceability, idempotency and reprocessing.
Spark · Airflow · Pandas · S3 · PostgreSQLSystems by design. Performance by default.
I build reliable data platforms, scalable backends, and observable systems.
01 / PROFILE
Engineering across the whole system.
I work where data, backend architecture and production performance meet. My focus is turning complex business workflows into systems that are easier to operate, observe and evolve.
Since 2013, I have built and modernized software across fintech, ERP, education, IoT, mining and data-intensive platforms — from small product teams to critical, large-scale systems.
I stay hands-on: designing architecture, writing production code, diagnosing bottlenecks, improving delivery practices and helping engineers make better technical decisions.

02 / OPERATING MODEL
Four connected engineering lenses.
Backend architecture
Pragmatic APIs and modular systems that keep business rules clear while scaling safely.
Python · FastAPI · Django · Node.js · RabbitMQSystem performance
Profiling, bottleneck removal, asynchronous workloads and high-availability thinking built into delivery.
Kubernetes · Redis · AWS · Queues · CI/CDObservability
Production signals that connect traces, metrics and logs to user and business impact.
OpenTelemetry · Prometheus · Grafana · APM03 / SELECTED WORK
Systems built around real constraints.
