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

Frontend for agent-based security workflows—streaming UIs, AI SDK integration, and shipping through high-frequency release cycles.

Built real-time streaming UI for agent-based workflows with Next.js and the Vercel AI SDK so users see step-by-step execution instead of blocking responses.
Developed frontend infrastructure for AI-driven systems, wiring agent execution into responsive, production-ready interfaces.
Led migration from Next.js 14 to 15—roughly halved bundle size and improved performance and load times.
Improved developer experience by moving from Yarn to Bun, cutting local build and iteration time.
Owned production stability—cleared 30+ P0 issues in the first month and kept releases steady under heavy cadence.

Dimension64 (Sarvantar AI)

Full-time

Rebuilt a legacy Angular admin as a responsive React and Next.js product—mobile-capable workflows and a maintainable component layer.

Replaced a legacy Angular admin with React and Next.js so workflows that were desktop-only worked reliably on mobile.
Ran the migration end to end—audit, scoped rewrite, incremental rollout—without disrupting active users.
Shipped core features including Mapbox-based vehicle search and a reusable component system aligned with product needs.
Worked with stakeholders to turn shifting operational requirements into stable UI flows.

Stack, craft, and how I work.

What I use in production—libraries and services that show up in real codebases. Icons are official brand marks from SVGL, so each row is a tool I work with, not a padded keyword list.

Things I've built.

Triboon

Full-featured project management: tasks, role-based dashboards, and real-time collaboration. Firestore and the Realtime Database keep state in sync across clients; role-aware UI reflects permissions.

RapidLogr

Log exploration with server-side filtering by search, severity, and time range so performance stays predictable on larger datasets. Filters and pagination sync to the URL for shareable, reproducible views.

Hirelink

Internal hiring portal built at EXL: candidates move through a structured five-stage pipeline (application → screening → interview → offer → onboarding). Recruiter dashboard shows per-stage counts, status history, and bottlenecks—built to replace spreadsheet tracking.
