01
Enterprise integration
Connecting sustainability data with enterprise planning
Designed a reusable export platform and secure integration pipeline capable of processing millions of ESG records across different enterprise data models.
- Challenge
- High-volume transfer, schema alignment, secure APIs, global environments, and safe failure recovery.
- Architecture
- Separated generic dataset generation from the Planning Analytics delivery component, with controlled batches, validation, retries, logging, and restartability.
- Outcome
- Created Envizi’s first commercially available outbound integration and a reusable export capability for future analytics use cases.
02
Cloud modernization
Moving ten million attachments safely to object storage
Led the solution design and core development of a reusable .NET Core attachment platform backed by AWS S3.
- Challenge
- Migrate approximately 10 million database files globally without planned customer downtime.
- Architecture
- Stable object references, authorization-first pre-signed URLs, restartable batches, reconciliation, targeted retries, and a controlled rollback window.
- Outcome
- Completed the migration across global environments and reduced database storage by an estimated 300–400 GB.
03
Platform security
Creating reusable, granular reporting authorization
Replaced broad report visibility with a consistent authorization model spanning access levels, work roles, groups, and individual users.
- Challenge
- Protect sensitive reporting information while supporting complex enterprise organizational structures.
- Architecture
- A reusable workflow across SQL, .NET services, APIs, Power BI integration, and the user experience.
- Outcome
- Established a foundation for future reporting-security capabilities and reduced routine support dependency.
04
AI-assisted operations
Turning natural-language questions into production diagnostics
Developed an MCP and OpenSearch framework that converts an engineer’s question into diagnostic queries for Power BI refresh investigations.
- Challenge
- Engineers manually searched large log volumes and repeatedly constructed complex operational queries.
- Architecture
- Natural-language intent translated into OpenSearch DSL with relevant execution, workspace, gateway, and dataset context.
- Outcome
- Reduced investigation effort by an estimated 60% and created a foundation for automated diagnostics and proactive monitoring.
Technical leadership
Building engineering capability alongside platform capability.
I have mentored approximately 20 engineers across architecture, SQL performance, Power BI, APIs, production troubleshooting, cloud design, deployment, and validation. I also lead recurring engineering sessions across India and Australia to discuss architecture decisions, production issues, and reusable implementation approaches.
Experience
Building across industries and scale.
