  • Websites

    Fast, SEO-ready sites for businesses and personal brands.

  • Web apps

    Booking, admin and internal tools that work on every screen.

  • Dashboards

    Real-time data, charts and reports people actually use.

  • Landing pages & stores

    Launch pages and catalogues with payments built in.

Performance

Helps users focus on the task, not the spinner.

I profile first, then fix what's actually expensive — state colocation, memoisation, code splitting, lazy loading and virtualised data. The results show up in production metrics, search rankings and revenue — not just in Lighthouse.

Large-dataset dashboard render−30%
Real-time alert latency−40%

Measured, not guessed. Three production wins across two companies, each measured against the previous release.
  • Semantic landmarks
  • Keyboard-reachable controls
  • Visible focus states
  • Reduced-motion support
  • Lazy-loaded media
  • Route-level code splitting
Accessible by default. Semantic HTML, ARIA where it earns its place, keyboard paths and lazy-loaded media — the habits behind better Lighthouse scores.

Design

Makes a statement without saying a word.

I obsess over spacing, type and states — and build them as tokens and components so a product can wear a different brand without a different codebase.

Designed to handle the real world. Loading, empty and error states — designed together, so every client's version feels finished and users always know what's happening.

Under the hood

Get serious reliability, not just pixels.

Good-looking UI is table stakes. What keeps a product healthy is the engineering nobody sees.

  • Payments that convert.

    Razorpay subscription billing for SaaS plans, with careful states for retries, failures and renewals.

    +15%successful transaction throughput

  • A service layer, not spaghetti.

    REST integrations behind a typed service layer that owns async data, errors and retries.

  • Tested where it matters.

    Jest unit tests across components, utilities and key flows — so releases stay boring.

  • Inclusive interfaces.

    Semantic markup, ARIA practices and keyboard paths from the first commit, not the last.

  • Docs that onboard.

    Written architecture, data-flow and API docs that let the next engineer ship in their first week.

  • A teammate in the loop.

    Agile delivery with backend, QA and UI/UX — feature work, debugging, code reviews and production releases.

Career journey

A career that keeps getting updates.

From a BSc in Belagavi to shipping production React at two companies and launching my own products — every release a little more capable than the last.

Why hire Sammed.

  • Ships end to end.

    Two live products built solo — from database to deploy, SEO and monetisation.

  • Performance, measured.

    20–40% wins on render time and latency, verified in production.

  • Real-time fluent.

    WebSockets, live dashboards and streaming market data are home turf.

  • Thinks like a product owner.

    Analytics, Search Console and growth metrics inform what I build next.

  • Easy to work with.

    Clear docs, honest estimates and code reviews that teach, not just block.

Frequently asked questions.

What kind of roles are you looking for?

Frontend or product-engineering roles where UI quality and performance matter — React, Next.js and TypeScript codebases, ideally with real-time data, dashboards or consumer-facing products. Open to on-site, hybrid or remote roles.

Have you shipped products on your own, end to end?

Yes. Stocker and optionchain.in are live products I designed, built, deployed, optimised for search and monetised myself — from the Supabase data layer to the Next.js front end, analytics and AdSense.

How do you approach frontend performance?

Measure first, then fix the expensive thing: render profiling, memoisation and state colocation, code splitting and lazy loading, and keeping large datasets virtualised or paginated. That approach cut render times 20–30% on production dashboards.

Do you write tests and documentation?

Yes — Jest unit tests for components, utilities and key flows, and written documentation covering project structure, component architecture, API integration and data flow so new teammates can onboard quickly.

How do you use AI tools in your workflow?

Claude Code, OpenAI Codex and Antigravity speed up scaffolding, refactors and test writing. Architecture, review and the final call on every line stay with me.

What does this portfolio itself demonstrate?

A statically exported Next.js App Router site in TypeScript and Tailwind CSS v4: typed content model, server components by default, small client islands for interactivity, no animation library, reduced-motion support, structured data and a 100-target Lighthouse budget.

Let's build what's next.
