  • Injection Mould Cost Estimator — screenshot3D web app

    Injection Mould Cost Estimator

    A browser-based 3D app that turns a part's STEP, IGES or STL CAD file into a DFM report, mould layout and cost quote in minutes. Owned end to end, from requirements and solution design to testing and delivery across nine iterative releases, fully client-side so customer CAD data never leaves the device.

    ~8 s to analyse a 50,000-face CAD part in the browser

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.

Visitor Management render time−20%
Large-dataset dashboard render−30%
Real-time alert latency−40%

Before After

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.

One UI, every brand. On VisionFacts, I restyled the product to each client's brand, theme and requirements. Pick a theme — it's the same component.

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.
