• I work at Gojek's ride-hailing arm where we are making world-class transportation and mobility products that are used by over 4 million users daily.
• Highlights:
• Ride Negotiation Engine: Led the design and implementation of a ride negotiation feature, including system and database architecture. Developed REST and gRPC APIs to facilitate cross-functional team integration. Created the development plan, aligning engineers and QA to it. Served as the single point-of-contact between teams. Innovatively implemented MQTT for real-time bid streaming, setting a new standard for frontend-backend communication and opening avenues for further use cases.
• Dynamic Configuration: Engineered a dynamic configuration system for backend microservices using Kafka and sidecar architecture, enhancing operational flexibility by enabling configuration updates without redeployment. Empowered product and business stakeholders to manage their own configurations, reducing developer effort and achieving a 40% reduction in monthly deployment rates.
• Order Management System: Played a pivotal role in evolving Gojek’s ride-hailing Order Management System (OMS), significantly boosting scalability and reliability to efficiently handle over 2 million daily orders and process more than 14 million events. Refactored the order state transition system for improved readability, extensibility, and robustness. Enhanced system error and fault visibility by implementing comprehensive logging and monitoring solutions, leading to quicker issue resolution and increased operational efficiency.
• Ownership: Served as primary owner of Gojek’s Notification Actor, App Metadata Service and Homepage Service. Reviewed 100+ PRs and refactored major parts of these services.
• Tech Stack: Go, Python, Clojure, Kafka, PostgreSQL, Redis, REST, gRPC, protobufs, MQTT, Google Cloud Task, Graphana, PromQL, NewRelic, Docker, Kubernetes and Linux

• Highlights:
• Worked on backend, including developing microservices and writing APIs, for Singapore Taxi and Vietnam 4-Wheeler.
• CPU Optimization: Optimized my team’s Go microservices through CPU profiling and load testing using PProf. Addressed performance issues causing frequent CPU overload alerts during peak traffic of 700,000 RPM. Identified and resolved an I/O process bottleneck, reducing the average response time of the a public API from 50+ ms to 9 ms and decreasing average CPU usage by 54%. Successfully reduced the server cost by 38%. Authored and published a comprehensive tutorial on the optimization process enabling other teams to follow suit.
• Ride Scheduling: Developed a ride scheduling microservice with job execution and retry support, including architecture and database design. Implemented custom scheduler using cron jobs and database polling. Created APIs, ride scheduling logic, and unit tests. Collaborated with the pricing team, and contributed to the pricing engine for scheduled booking pricing logic.
• Refactored transport's notification actor and rewrote multiple business logic involving notifications for customers and drivers. Reduced exceptions and error percentage on the microservice from 25% to 0%.

• Highlights:
• Google Maps Integration: Integrated Gojek with Google Maps’ Request a Ride feature by developing a Java microservice for parallel processing, aggregating, and sending cab availability data. Utilized Quartz for job scheduling and multithreading to efficiently compile driver availability data into Google’s feed format. Employed SFTP to periodically transfer data to Google Maps.
• Tech Stack: Java, Go (Golang) and PostgreSQL.
