Igor Ostaptchenko, Detroit MI — Senior/Staff Elixir Engineer, 13 years on the BEAM (Remote US, UTC-5)

About me

I have been shipping Elixir and Erlang in production since 2011 — starting with Erlang at Credorax (PCI credit card processing, Boston/Malta), then Elixir across AcuityAds, RBC Capital Markets, AEON, Clarity Voice, HubSpot, and most recently Estée Lauder’s Tom Ford e-commerce platform. I currently teach Deep Learning (IE 7860) at Wayne State University in Detroit and maintain 19 active open-source Elixir/Rust projects.

What I bring

• Phoenix LiveView — production customer-facing work at Estée Lauder. I prefer LiveView over React and have for years.
• Oban — production at Estée Lauder alongside Kafka and RabbitMQ. Queues, retries, unique constraints, cron, dead-letter handling, concurrency tuning.
• Ecto + PostgreSQL — primary database across every role. Aurora PostgreSQL at Rocket Mortgage (7 years AWS), including diagnosing a 10M-row performance issue.
• PropEr / proper_statem — 23 properties, 3 stateful models, ~700 adversarial command sequences, 3 bugs found that point tests missed. Paper submitted to the ACM SIGPLAN Erlang Workshop 2026 at ICFP: sim_ex: Verifying a Concurrent DES Library with PropEr.
• Distributed systems — OTP supervision trees, :erpc, GenStage, Task.async_stream. Five distributed database clusters across the Atlantic at Credorax. Kubernetes/Helm/Terraform across multiple roles.
• Rust NIFs — sim_ex Rust NIF engine at 6.4M events/sec. ex_stochtree (BART port). Comfortable at the Elixir/Rust boundary.
• Golang — production alongside Elixir at Estée Lauder.
