Scalable Document Delivery Platform
01 / 06
Designed a scalable document delivery platform capable of handling 100 files and 2,000 delivery tasks per job, targeting ~90,000 tasks/day with a 500ms p99 submission acknowledgement.
02 / 06
Designed an asynchronous Job Queue, Fanout Worker, Task Queue pipeline using AWS SQS and Lambda, enabling backpressure, failure isolation, retries, DLQs, and horizontal scalability.
03 / 06
Architected PostgreSQL job/task models with RDS Proxy, idempotent workers, conditional processing, and integrity checks, with S3 presigned transfers for secure file staging.
04 / 06
Designed real-time delivery tracking using API Gateway WebSockets, allowing clients to observe job and task progress as processing happens.
05 / 06
Designed and provisioned the cloud architecture with Terraform, integrating AWS services, security controls, storage, queues, compute, and real-time communication.
06 / 06
Currently implementing the architecture through agentic workflows, using ADRs and Technical Design Specifications to translate architectural decisions into production ready components at AI godspeed without compromising code quality. AKA Spec Driven Development.

What former
teammates say.
Recommendations from managers, mentors, and teammates.
Rayane consistently demonstrated deep technical expertise and strong architectural judgement. She took ownership of complex dynamic payment workflows, leading the architecture decisions and implementation across multiple entry points. Reliable and an absolute pleasure to collaborate with.
Illia Kurochkin
Software Engineer
Aug 2026
Managed Rayane directly at Navro
Her growth during our time together was astronomical. She started with Next.js and expanded well beyond her initial scope: Spring Boot, microservices, increasingly complex backend systems. The difference between the engineer I hired and the one I eventually worked alongside was remarkable.

Hired Rayane into her first engineering role
I saw her pick up work in areas she had no experience in and totally smash it. Very well self-managed, capable of identifying issues and driving them from design to implementation. To her future teammates: you got a good one. The rest of us are jealous.

Her reviews are now something I actively seek for my own PRs. Ray approaches challenges with a fearlessness that is as rare as it is inspiring. She doesn't just face obstacles; she embraces them, learns, and comes out stronger every time.
