Design career path

Owned the design and implementation of automated deposit and withdrawal infrastructure, processing 10000B+ IRR in financial transactions and significantly reducing manual operations.
Increased deposit auto-approval rate from 48% to 92% by redesigning transaction validation, reconciliation, and configurable matching rules based on production insights.
Designed a fault-tolerant settlement system with strict provider isolation, idempotency guarantees, duplicate prevention, and independent transaction state validation.
Increased backend concurrency capacity by ~4× through PHP-FPM tuning and performance optimization without additional infrastructure cost.
Improved platform observability by implementing monitoring dashboards, payment-provider health metrics, and incident analysis workflows, reducing troubleshooting time and operational risk.

Partner with clients’ technical teams to ensure seamless system integration and alignment with project objectives.
Lead the transformation of legacy, monolithic codebases into clean, modular architectures, enhancing collaboration with front-end and mobile development teams.
Design and implement robust CI/CD pipelines, streamlining development and deployment workflows for improved efficiency and reliability.
Establish a structured process for task management and technical documentation, fostering clarity and operational excellence across teams.


Built a high-traffic microservice to handle IoT devices' webhooks efficiently.
Developed a chat microservice to enhance communication between drivers and the operations team.
Reduced network usage costs by optimizing old and legacy queries in the system.
Improved resource usage by approximately 70% through the implementation of an OPCache layer in the core
