Summary
🤩
Rockstar🎓
Top SchoolSendil Nellaiyapen is an engineering leader with a decade of experience building high-performing payment and wallet platforms at Uber, currently leading a greenfield Payment Selection initiative in Eindhoven. He has a proven record of scaling teams from the ground up, shaping culture and operating models, and driving measurable product and top-line improvements across checkout and wallet experiences. A hands-on polyglot engineer turned manager, Sendil continues to contribute to open source—tangible work on prominent projects like webpack, wasm-bindgen, Servo and JHipster demonstrates deep expertise across front-end, back-end and WebAssembly toolchains. He combines operational rigor (hiring, process design, reorganizations) with technical depth, having led major migrations such as Flow-to-TypeScript and launched features that reduced costs and improved user metrics. Known for fostering collaboration through tech talks and events, he also drives DEI and internship programs to grow local engineering talent. His background in large-scale web payments and open-source contributions makes him comfortable bridging product strategy with low-level systems optimization.
