Software Developer at Wish and Cook Lda

March 1, 2021 - Present

Sole engineer for the platform end-to-end: designed reliable asynchronous order orchestration per kitchen queues using Django, Celery, RabbitMQ, and Redis (at-least-once delivery, idempotent processing, retry/recovery). Built marketplace data model with role-based accounts, recipe customization via nutritional info, and shop + time-slot based ordering and dynamic delivery. Engineered a capacity-bound reservation system with rolling 7-day inventory slots capped to physical cooking spot capacity to prevent overselling. Built a NestJS kitchen execution engine and recipe-to-action compiler with dependency-aware, concurrent execution across up to 24 cooking spots and up to 8 transport cars. Implemented hybrid in-memory + Redis state storage for low-latency execution tracking and crash recovery. Developed tick-based navigation for transport cars resolving grid path conflicts; converted resolved paths into per-cell MQTT move commands with response-based progress. Root-caused and fixed distr

Software Developer (Sole Engineer) at Wish and Cook Lda

March 1, 2021 - Present

Owned end-to-end architecture, implementation, and operations for an asynchronous order orchestration platform and cloud-to-edge kitchen execution system. Built reliable order execution using Django, Celery, RabbitMQ, and Redis with at-least-once delivery, idempotent processing, and robust retry/recovery across cloud and kitchen services. Designed data models for role-based accounts (general, chef, influencer, admin), recipe customization, and shop/time-slot-based ordering. Implemented a capacity-bounded reservation system with rolling 7-day inventory slots to prevent overselling. Developed a kitchen execution engine (NestJS) compiling recipe steps into sequenced, dependency-aware actions supporting concurrency across cooking spots and transport carts. Added low-latency hybrid state with Redis-backed storage and crash-recoverable execution tracking. Built observability scaffolding (Prometheus, Grafana, Loki, Alloy) and maintained stateless deployment (Docker, Nginx) for horizontal scal
