Building a distributed merchant catalog platform (Go, gRPC, PostgreSQL, Kubernetes) powering marketplace search and mobile apps. • Scaled the marketplace catalog from 1M to 8M products by integrating new merchant sources (Shopify, Zid, Amazon). • Designed and shipped automated moderation with ML-assisted item enrichment, increasing moderation throughput and cutting manual review workload. • Led regulator-required geo-sharding of the catalog infrastructure, enabling a near zero-downtime cluster split.

Marketplace for fashion, electronics, and related goods. Worked on a microservices team owning product-data ingestion, processing, and storage (Go, REST, Datadog). • Scaled the product catalog from 100K to 1M+ published items. • Cut average product-publication time by 3x by streamlining the moderation pipeline. • Automated product ingestion from FTP-based sources, eliminating manual effort.

Grocery delivery platform from dark stores with in-house and external delivery. Backend development, external integrations, and database design (Go). • Decomposed a monolith into microservices (catalog, recommendations), reducing response time by ~15%. • Improved the recommendation model, lifting order conversion from recommendations by ~8%. • Integrated Uber Delivery, cutting delivery costs by ~30%. • Optimized the catalog service, improving stability under load by ~25%.

Led a team building shared test automation tools and frameworks (Python, Pytest) used across multiple QA teams. Drove the automation strategy and reduced time-to-test.

Led QA across multiple teams in the Consumer department: testing workflows, knowledge sharing, hiring, mentoring, and department-wide quality strategy.

Grew from QA Engineer to QA Lead within the company. Tested microservices for an omnichannel retail product and built my first Python/Pytest automation framework. As QA Lead, owned hiring, mentoring, and the quality strategy for the mobile app core team.

Functional, integration, and regression testing of POS-terminal software (“Unipos”) for payment/acquiring systems. Owned test documentation and API/UI validation (Postman, Swagger, SQL).

Functional, module, and regression testing of medical imaging web applications, with ownership of test documentation and reporting.

First-line technical support for the company's software: incident resolution, client consulting, and escalation.
