I build software for systems that are already running, already messy, and already important.
I am a software developer working as an Application Integration Specialist. My work sits close to production-critical manufacturing systems: backend applications, database-heavy logic, integrations, dashboards, and careful migration work. I like problems where the software has to be reliable because real people depend on it every day.

About
A practical builder with a systems mindset.
I care about software that works in the real world, not just in a clean demo. Most of the systems I work around have history, dependencies, edge cases, and people relying on them. That has shaped how I think: understand the system first, change it carefully, and measure whether the change actually helped.
My day-to-day work usually involves C#, .NET, SQL Server, Sybase, Dapper, IIS, and internal tools. I work across backend logic, database performance, query behavior, and interfaces that help engineers see what is happening inside operational systems.
Outside work, I build iOS apps and small experiments when an idea feels useful enough to exist. I also like food, cars, late-night drives, and overthinking simple tools until they feel right.
Work
Work that sits close to operations.
I have worked across enterprise software, internal systems, and production-facing tools. The common thread is simple: make systems more reliable, easier to understand, and less painful to use.

I work on internal applications that support factory operations. These are not isolated side systems; they are connected to daily workflows, operational data, and tools used by engineers and operators. Reliability matters because mistakes or slowdowns can create real friction for the people using them.
A large part of my work is improving existing systems while they continue to run. That includes database migration work, query optimization, debugging long-standing issues, and building interfaces that make operational data easier to act on.
Migration from Sybase to SQL Server
Working on a live migration from Sybase to SQL Server, including query rewrites, schema differences, data behavior, compatibility issues, and gradual changes that have to be safe to deploy.

Query parser and validation logic
Designed logic to inspect SQL queries before execution: extracting operations, tables, joins, columns, and conditions so application rules can validate what a query is allowed to do.

Performance work that changed daily usage
Reduced a large-scale data snapshot process from about 4 hours to 10-14 minutes and improved several slow database operations from minutes to seconds.

Dashboards and internal tools
Built and improved dashboards and pages that help engineers monitor system status, view trends, update operational data, and reduce manual checking across internal workflows.

Monitoring
During my internship, I worked on internal software used for visibility into databases and systems. The work gave me a clearer understanding of how engineering tools need to behave when they support real operations, not just development environments.
I built and modified C#/.NET tools for database monitoring, connection alerts, system-health tracking, threshold-based diagnostics, and SQL viewing features with formatting and syntax highlighting.

Enterprise systems
I worked on enterprise backend applications and system-level software, where the focus was structured development, maintainability, documentation, and reliable delivery across larger teams and codebases.
My work included backend APIs, integration gateways, software package transfer, aircraft radar configuration-related systems, testing, documentation, and architecture planning. This role built the foundation for how I approach large systems today: understand the dependencies, communicate clearly, and avoid changes that only work in isolation.
Background
Education and technical foundation.
My background combines formal computer science education with hands-on experience in backend systems, databases, enterprise applications, and internal tools.
Education
Master of Science in Computer Science, Purdue University, Indiana. GPA: 4.0.
Bachelor of Technology in Information Technology, SRM University, India.
Technical base
C#, .NET Framework, .NET 8, Java, Spring Boot, REST APIs, SQL Server, Sybase ASE, MySQL, PostgreSQL, MongoDB, Dapper, IIS, AWS, JavaScript, Node.js, Express, and React.
Approach
How I like to work.
Start by understanding the system, not just the ticket.
Make changes that are safe for live environments and easy to reason about later.
Care about performance only where it changes the experience for real users.
Build tools that reduce confusion, not tools that add another layer of work.
Personal projects
Small things I build outside work.
These projects are not the whole story, but they show the kind of problems I get curious about: simple products, useful libraries, and experiments that help me learn by building.
iOS app
Nothing
Nothing is a quiet iOS app for taking a short pause. It includes a simple do-nothing mode, breathing support, Live Activities, and a deliberately low-friction interface for moments when people do not need another complicated wellness app.

Writing
Notes, when something feels worth writing down.
I do not write constantly, but I like having a place for practical notes, technical writeups, and the occasional personal system that helped me think more clearly.
