EXPERIENCE

Stepico Games – Backend Software Engineer (contract) (LiveOps infrastructure project)

September 2025 – May 2026
– Improved support team workflow efficiency and onboarding processes by delivering reliable, centralized
tooling and a unified view of account state.
– Built a real-time player lookup system as the BFF that aggregates data from multiple services using
Polly pipelines to present a unified and consistent account state, significantly improving data accuracy
and reducing resolution time for support inquiries.
– Introduced role-based access control to enforce secure, role-scoped access across support and
operational tooling.
– Implemented real-time configuration updates via a hot cache using the Redis cluster inside
ElastiCache, enabling instant, zero-deploy adjustments for live events and economic parameters,
increasing operational responsiveness.

GlobalLogic – Fullstack Software Engineer (Construction CRM project)

January 2025 – July 2025
– Enhanced workflow efficiency and real-time data synchronization by implementing an event-driven
invoicing system, reducing processing delays.
– Built a reliable invoice synchronization pipeline across distributed modules, reducing data
inconsistencies and ensuring timely financial updates across the platform.
– Introduced distributed locking mechanisms using RedLock for high-concurrency budget operations,
preventing race conditions and improving data integrity.
– Delivered an interactive financial dashboard, providing stakeholders with real-time visibility into budgets
and invoices, improving decision-making and reducing manual negotiations efforts.
GlobalLogic – Fullstack Software Engineer (Agriculture CRM project)
March 2024 – December 2024
– Improved operational planning capabilities across workflows by delivering robust inventory
synchronization mechanisms and data processing capabilities.
– Implemented advanced spatial querying using PostGIS for precise field area calculations and logistics

optimization, improving planning accuracy by 10% and reducing manual overhead.
– Built a grain reservation system leveraging optimistic locking to maintain consistency between physical
inventory and commercial contracts, ensuring data integrity under concurrent operations.
– Designed and optimized relational data models and indexing strategies to support efficient querying of
spatial and transactional data, reducing latency and improving system scalability.
