01 / PROFESSIONAL IDENTITYMore than a resume.
More than a resume.
A body of engineering work.
My professional path began in testing and commissioning—working directly with substations, power plants, protection schemes and primary equipment. That field foundation continues to shape how I approach engineering decisions today.
Over time, the work expanded into digital substations, global protection-platform validation, relay-testing technology, engineering software, utility modernization and leadership of cross-functional engineering teams.
“Translate field lessons into engineering standards, scalable technology and better decisions.”
Where field physics meets
digital engineering.
High-Voltage Systems
Substation commissioning, energization readiness, FAT/SAT, retrofit programs, switchgear and high-voltage infrastructure.
Digital Grid
IEC 61850 automation, digital substations, system integration, SCADA, cloud-enabled testing and digital-twin workflows.
Engineering Leadership
Global teams, engineering governance, technical strategy, capability development, client advisory and cross-functional execution.
From commissioning engineer
to global engineering leader.
Field Foundation
Testing & Commissioning Engineer — substations, generation, industrial systems, protection relays and maintenance testing.
Digital Substation Commissioning
ABB India — protection, IEC 61850 station automation, retrofit and high-voltage commissioning, including a landmark 400-kV digital substation.
Global Platform Validation
ABB Sweden — coordination of hardware, software, firmware and IED validation across multinational engineering teams.
Applications & Market Leadership
Megger India — relay-testing applications, technical leadership, customer engagement and regional business growth.
Technology & Engineering Leadership
Megger Group — protection software, automation, digital testing, global engineering programs, utility modernization and director-level leadership.
Field credibility backed by specific engineering outcomes.
Selected public examples show the voltage classes, protection domains, technologies and responsibilities behind the experience—from commissioning and retrofit execution to global product validation and modern protection testing.
Landmark digital-substation energization
Protection validation, IEC 61850 station integration, commissioning and energization-readiness work associated with India's first 400-kV IEC 61850 digital substation.
- High-voltage protection and control
- System integration and site validation
- Commissioning through energization readiness
50+ feeder protection retrofits
Retrofitted more than 50 220/110-kV transmission feeders from legacy MM3V/SSR3V schemes to REL511 distance protection while maintaining continuity of the transmission assets.
- Legacy-to-numerical protection migration
- Distance protection and secondary-system verification
- Field execution without line shutdown or maloperation
Protection across the primary system
Hands-on testing and commissioning across generator, transformer, line, busbar, reactor, feeder and motor protection in utility, generation and industrial environments.
- Relay testing and troubleshooting
- CT/VT and trip-path verification
- FAT, SAT, commissioning and maintenance testing
Multinational protection-platform validation
Coordinated validation work across Sweden, Switzerland, Finland and India, connecting hardware, software, firmware and IED behavior with practical protection requirements.
- Cross-functional engineering coordination
- Platform and application validation
- Translation of field requirements into product engineering
Modern end-to-end protection testing
Technical work on centralized, synchronized end-to-end testing for POTT, PUTT and line-differential applications, including percent-differential and alpha-plane behavior.
- GPS / IRIG-B synchronized injection
- Dynamic, search, shot and timing tests
- Cloud-enabled single-end control workflows
Field testing with low-power instrument transformers
Published technical work on LPIT inputs in high-voltage switchgear and practical protection testing for modern digital-substation architectures.
- LPCT / LPVT measurement chains
- IEC 61850-oriented protection testing
- Field validation of emerging measurement technology
