• Eliminated recurring P0 incidents by introducing a Memcached proxy layer, reducing connections from ~65K per node to ~3.6K cluster-wide and stabilizing cache access under peak load

• Migrated 20+ services from EC2 to AWS EKS, reducing infrastructure costs by 30–40% and improving deployment speed by ~2x

• Reduced infrastructure costs and accelerated deployments and rollbacks by 3x through migration from external AWS load balancers to in-cluster Kubernetes networking

• Stabilized cluster networking by migrating Datadog communication from TCP to Unix sockets, reducing TCP retransmits to near zero and significantly decreasing inter-service timeouts

• Reduced infrastructure overhead by replacing per-service consul-template sidecars with a centralized ConfigMap-based solution, eliminating thousands of containers and significantly reducing cluster resource usage

• Built MCP server to integrate LLM tooling with Prometheus, improving observability workflows and reducing debugging time

• Led system modernization initiatives (PHP 7 → 8, CakePHP 3 → 4), reducing technical debt and improving runtime efficiency

• Contributed to MySQL 5.7 → 8.0 upgrade by updating queries and validating production readiness during rollout

• Improved performance of high-load PHP monolith through database optimization and caching strategies, reducing database load, redundant cache calls by up to 2x and lowering total memory footprint

• Increased application performance by ~30% by enabling PHP 7.4 via incremental CakePHP upgrades

• Reduced instance provisioning time by 20–30% through EBS-backed infrastructure improvements

• Optimized messaging infrastructure by redesigning NSQ topology for Kubernetes, improving resource efficiency by 2x+

• Evaluated Redis as caching layer and drove rollback decision based on cost/performance trade-offs, maintaining lower latency and infrastructure cost with Memcached

• Led backend development across IoT and telecom platforms, designing scalable systems for device management, billing, and communication workflows

• Designed custom MySQL replication architecture to isolate client data, significantly improving query performance and enabling per-customer database access

• Built B2B APIs and billing platform supporting dynamic plans and usage-based calculations

• Developed event-driven workflows integrating external services (Twilio, Google Cloud Print, stamps.com), automating photo printing, packaging, and delivery

• Reduced infrastructure costs by ~4x by migrating from bare metal to virtualized environment (Proxmox) while maintaining performance and improving maintainability

• Introduced CI/CD and development environments, improving delivery speed and consistency

• Led code quality initiatives including refactoring and automated testing

• Led technical strategy and execution for trading platform, including backend, infrastructure, and integrations

• Managed engineering team and drove architecture decisions

• Built C++ plugins and API bridges for MetaTrader, enabling full programmatic control and eliminating manual workflows

• Architected high-performance MySQL databases for large datasets

• Built internal tools and monitoring systems

• Developed backend systems and trading integrations for forex platform using PHP and C++

• Built C++ plugins extending MetaTrader capabilities and enabling automation

• Designed REST APIs and optimized MySQL queries for large datasets
