Cross-squad engineering support, building solutions and participating in architectural decisions and migrations to improve developer experience across teams.

• Designed and shipped internal AI skills and agents that automate repetitive engineering workflows, freeing developers to focus on higher-value work.
• Defined adoption patterns and best practices for AI-assisted development across squads.
• Built the platform's managed API Gateway from scratch, a NestJS control plane for versioned routing and policy config plus a streaming data-plane proxy serving ~25M requests/month in production, removing the need for a commercial API management subscription (Apigee, Sensedia, Kong Enterprise) and its vendor lock-in.
• Modeled gateway configuration as data, so routes, policies, IP allow-groups, distributed rate limits (Valkey) and etc publish and roll back without a redeploy, with shadow mode to measure impact before enforcing.
• Introduced architectural patterns such as Strategy, Specification, Policy, Saga, etc., ensuring responsibility isolation and improving service maintainability.
• Integrated OpenTelemetry across microservices for improved observability, including the gateway's SLOs and burn-rate monitors as code, and built dashboards for clear system visualization.
• Participated in defining and adapting GMUD (change management) processes for the team.

Led architecture and engineering across multiple squads for the BOSS platform (BSS + OSS) powering mobile consumer, B2B, MVNE, and MVNO services.

• Led the Concierge (B2B) and MVNX (MVNE/MVNO) squads, mentoring engineers, driving architectural decisions, and building the MVNX platform from scratch.
• Designed TCP/socket libraries for direct communication with 5G core network elements, and built a cross-service audit middleware used across back-office, API integrations, and the MVNX platform.
• Created the core ABAC + RBAC permission system from scratch, handling all platform authorization.
• Participated in key decisions and implementation of a critical optimization of the customer renewal flow, reducing processing time from 3 days to under 6 hours.

Architected and built core telecom infrastructure, participating in technical decisions from early platform design through production.

• Developed 60+ mission-critical microservices for mobile telephony on Node.js, PostgreSQL, Kafka, and GKE, maintaining 99+% SLA.
• Co-architected the BOSS platform (BSS + OSS) following ODA standards, operating the entire mobile telephony stack.
• Built a high-throughput binary processor for network CDRs (Call Detail Records), continuously optimized for big data volumes.

Main developer for the web platform. Led architecture decisions and implementation, built the new acquisition portal, site pages, and blog system.

Backend-focused development. Participated in architecture decisions, created new microservices, and split oversized services into smaller, focused units.

Backend and mobile development across Node.js services and a React Native application.
