Profila

A CV scoring product that treats resumes as sensitive data — honest measurement, in-app improvement, and production discipline around privacy, access, and slow inference.

Problem:

Most CV tools either over-claim what a score means or treat resume uploads as disposable, with little real access policy or operational discipline behind the model call.

Solution:

A product split between interface and engine: privacy-first ingest, capability-based access, fair limits, and analysis moved off the request path.

Result:
A live product with an honest score loop, durable CV versions, and a system that stays private and responsive under constrained inference.

Notification Center

Event-driven notification microservice that became the organization-wide standard for reliable, multi-channel delivery at scale.

Problem:

Product-specific notification implementations were unreliable under load and hard to operate as a shared platform concern.

Solution:

A centralized, fault-tolerant event-driven microservice with queues, retries, and clear ownership across products.

Result:
Organization-wide adoption, higher engagement, and stronger delivery reliability at millions of monthly events.
