Frontend engineer by craft,
Agentic AI by obsession.

I'm Gagan Kumar. My strongest work is on the frontend and product surface—AI-assisted interfaces, motion, and the layer where a complex stack still has to feel obvious to the person using it.

Lately that obsession shows up as pentesting automation and autonomous agents—attack-surface reasoning, real vulnerabilities, minimal hand-holding. The domain is unforgiving; the abstractions have to earn their keep.

I still split time between AI frontends, orchestration, and whatever comes next for agentic workflows. From pixel-level UI to systems that think and act on their own—the surface and the machinery have to agree.

Impact you can trace.

Roles, internships, and education in one place—AI agents in production, framework upgrades, and how I learned the stack. Skim the bullets; they're the signal.

Current focus

Astra Security

Full-time

Building AI-powered pentesting agents and customer-facing tools in a security product org—where the UI has to keep up with fast-moving agentic workflows.

Built real-time agentic workflow UIs that surface multi-step AI reasoning to non-technical users — handling streaming states, partial results, and agent handoffs in a production React/Next.js app.
Own full lifecycle of frontend framework upgrades — from dependency audit and migration planning through rollout and regression coverage — keeping the product shipping without freezing the roadmap.
Partner with product and engineering stakeholders to translate technical debt into sequenced, committable plans; reduced cross-team friction on stack decisions.

Dimension64

Full-time

Product engineering in a fast-moving team—shipping features while modernizing how the codebase kept pace with the roadmap.

Led end-to-end migration of React and Angular codebases — from audit through staged rollout — with clear regression ownership and zero unplanned downtime.
Drove cross-squad upgrade coordination so framework changes landed on schedule, not as emergency fire drills.
Shipped customer-facing features on a modernized, maintainable stack with cleaner module boundaries and significantly less glue code.

Software Development Intern

EXL Service

Internship

Owned the Hirelink hiring portal end to end in a short window—backend business rules, responsive UI, and alignment with HR stakeholders.

Built Hirelink hiring portal end-to-end in a 6-month window — .NET Core MVC backend, Tailwind UI, applicant tracking and recruiter workflows — production-bound, not a demo.
Translated ambiguous HR stakeholder requirements into shippable milestones; paired with senior devs to write patterns that survived handoff.
