Specimen CI Integration GitHub Link

●Contributed to Specimin, a modular program reducer for debugging compilers and type systems by slicing large Java programs into minimal reproducing inputs.

●Designed and implemented a CI/CD pipeline using GitHub Actions to automate testing across multiple projects and validate reductions on various compilers and type checkers, improving feedback speed for researchers and developers.

Associate Systems Analyst Sep 2021 – Aug 2023

NSEIT Limited Mumbai, MH

●Built support for advanced order types such as FAK (Immediate or Cancel) and FOK (Fill or Kill), in a Java-based Order Management System (OMS), working with FIX protocol messages like New Order – Single (MsgType=D), Execution Report (8), and Order Cancel Request (F)

●Used Redis to implement caching for high-frequency order book reads, reducing latency by 40% and boosting responsiveness of the real-time FIX Market Data Broadcast Engine

●Modularized the Net Open Capacity (NOC) logic by extracting it from the OMS into a separate Java service, integrating NLDC API automation and introducing a Memcache layer to improve data retrieval and reduce system bottlenecks

●Implemented RPO trading sessions for green and non-green sources of renewable energy using pro-rata allocation based on order demand under REC contract.

●Designed and implemented forward and reverse auction flows with a flat-fee pricing structure for bilateral long term products( month ahead contracts), using Java to increase system flexibility and drive revenue for the trading platform
