• Exploring early-stage products and internal tooling in AI-driven systems, automation, and assistant-style workflows for complex, multi-step tasks.

• Ran a home-sharing pilot on Airbnb (“Stevens Nook”), focusing on guest experience and day-to-day operations; closed the listing when I moved.
• Did a short period of part-time rideshare driving as a side hustle, gaining firsthand exposure to routing, timing, and service constraints.

• Took a planned career break between full-time roles to travel, rest, and reset after several intense years in systems engineering.
• Focused on personal reflection, health, and long-term life and career planning.
• Returned from the break with clearer priorities around where to live next and what kind of work to pursue.

Automotive safety systems engineer for System-in-Package (SiP) and System-on-Chip (SoC) products, aligning with ISO 26262.

• Analysed automotive system use cases and the responsibilities of each sub-system.
• Performed system modelling using Enterprise Architect (BDD, state machines, sequence/activity diagrams).
• Carried out qualitative and quantitative functional safety analyses (FMEDA, DFMEA, DFA) for multiple SiPs and SoCs.
• Authored safety concepts and architecture specification documents for SoCs.
• Prepared diagrams and flowcharts for customer engagement and cross-team communication.
• Built Python scripts to automate documentation, safety analysis, and traceability workflows.
• Tracked IP and system-level changes using JIRA and maintained safety lifecycle traceability.
• Participated in internal and external safety audits and assessments.

Keywords: System Architecture & Design, ADAS/IVI, Automotive Systems, ISO 26262, FMEDA/DFMEA/DFA, JIRA/JAMA, Python automation.

• Implemented a tool qualification process for internal Qualcomm tools under ISO 26262.
• Performed gap analysis between the standard and current practices, and proposed a bridging methodology.
• Developed a proof-of-concept web app in Java Spring Boot to support the tool qualification process.

Keywords: Tool Qualification, ISO 26262, Java, Spring Boot, System Architecture.

• Designed and implemented an ML-based detection and mitigation system for CACC (Co-operative Adaptive Cruise Control).
• Simulated CACC and “attack” scenarios in Python to evaluate robustness.

Keywords: ML, Python, ADAS, Cooperative Driving, Simulation.

• Worked end-to-end in the SDLC for Maintenance Support System (MSS) used in metro and main-line rail.
• Derived system and software requirements, designed test cases, and implemented code changes.
• Developed REST APIs for a Spring Boot / Maven web app that managed health data and maintenance requests.
• Worked with PostgreSQL on RHEL for storing and querying health data.
• Collaborated with customer engineering teams to deploy and maintain MSS in the field.
• Handled bug fixes and enhancements in both frontend (HTML) and backend, using ClearCase and ClearQuest.
• Supported embedded software development for periodic maintenance of on-board computers in ERTMS trains.
• Maintained SDLC traceability using Reqtify.

Keywords: Java, Spring Boot, PostgreSQL, Web App Dev, Linux, System Architecture.

• Designed and developed a low-voltage control logic simulation for train control systems.
• Built a validation platform simulating the train operator’s console for Indian metro rail, accelerating the project roadmap significantly.

Keywords: ControlBuild, NI LabVIEW, PXI, Train Control.
