HMI Project Intern

Schneider Electric India, Bengaluru

[TIME: May – Aug 2025]

Engineered a Dark Theme UI for Industrial HMI Software

Took ownership of a full interface overhaul for Schneider Electric's EcoStruxure Operator Terminal Expert (EOTE) software, moving from a high-contrast default theme to a polished dark UI designed for operators working long shifts in demanding industrial environments.

01. UI Engineering: Built the dark theme interface using C# and WPF, handling styling, component theming, and visual hierarchy to ensure readability and consistency across all operator-facing screens.
02. Operator Experience: Focused the design around reducing visual fatigue — a critical factor for control room operators monitoring systems over extended periods in low-light industrial settings.
03. Development Lifecycle: Contributed to the HMI group's broader development pipeline, documenting software licensing enhancements and supporting feature integration across product releases.

Project Intern

Bahrain Electromechanical Services Company (BEMCO), Bahrain

[TIME: Jun – Jul 2024]

Contributed to a $525M Infrastructure Project

Worked on live electrical design and systems integration for the Bahrain Marina Development — a large-scale infrastructure project requiring precision engineering across grounding, protection, and building safety systems.

01. Grounding & Protection Systems: Designed and optimized grounding systems achieving sub-1-ohm resistance, and implemented lightning protection schemes to safeguard the facility's electrical infrastructure.
02. Electrical Distribution: Performed cable tray calculations to ensure a robust and code-compliant electrical distribution layout across the development's building network.
03. Building Safety Systems: Reviewed IFC drawings and supported installation of integrated safety systems — fire alarms, CO/heat sensors, CCTV, and access control — ensuring strict adherence to project specifications.

Outreach Lead & Electrical Engineer

Team Ojas Racing (Formula Student)

[TIME: May 2024 – Present]

Engineered a Decentralized ECU & BMS Architecture

Moved away from a monolithic controller to a distributed network of CAN-connected nodes, significantly reducing wiring harness complexity and weight by placing acquisition modules closer to their signal sources. This architecture integrated a custom Master-Slave BMS to accommodate the battery stack configuration.

01. High-Voltage Integration: Architected the 600V system integration, implementing isoSPI for noise-immune battery monitoring (BMS) in an electrically noisy environment.
02. Safety & FMEA: Led Failure Mode and Effects Analysis (FMEA) to validate safety-critical logic, ensuring compliance with strict EV racing regulations.
03. Review Process: Established a rigorous DFM/DFA review pipeline for schematics and PCB layouts, reducing hardware re-spins.

Design Head

Instrument Society of India (ISOI) — VIT Vellore

[TIME: Jun 2024 – Jul 2025]

Led Visual Design for a Major Student Technical Chapter

Built and managed the chapter's visual identity — producing high-visibility creatives for some of VIT's largest events while mentoring the next generation of designers in Figma and Canva.

01. Event Creatives: Designed 25+ posters and promotional materials for flagship fests Riviera and Gravitas, displayed across major VIT venues to drive student engagement and event visibility.
02. Event Execution: Organized hackathons and technical events end-to-end — managing planning, faculty coordination, and on-ground execution to deliver consistent, well-run experiences.
03. Team Mentorship: Led and mentored a team of junior designers in Canva and Figma, standardizing design workflows and maintaining a consistent visual identity across all chapter communications.
