Hey, I'm Siddhant

An engineer. A tinkerer.

I'm an Engineer at YouTrip, a multi-currency fintech company based in Singapore. I work primarily with Flutter and Dart, but I'll pick up whatever the problem needs: Swift, TypeScript, Python, SvelteKit, Chrome extensions, LLM pipelines. If it solves the problem, I'll learn it.

What I'm building at YouTrip

I own three packages as CODEOWNER: Remittance, Card, and In-App Exchange. I co-led the Mobile Chapter in 2025 and work across four repositories.

  • YouTrip Family

    The most complex thing I have shipped.

    A parent-managed child wallet. Parents create accounts for their kids through MyInfo KYC, set spending controls, fund wallets and get real-time alerts. Kids get a physical card and optional app access. I built the token exchange mechanism, the child home screen, the parent dependents view, card activation, controls, nudges, and the scam and blocked flows. The nudge implementation shipped from scratch in a single sprint. Thirteen pull requests between December 2025 and April 2026.

  • FX Rate Automation

    The one I am most proud of.

    Two tools built from scratch. A Chrome extension that pulls competitor rates from the Visa and Mastercard APIs, 22 currency pairs and 44 rates in 20 seconds, straight into Google Sheets. And an AI-powered mobile automation framework using GPT-4o-mini that captures real-time rates from Instarem and Wise across Singapore, Australia and Thailand. Twelve currencies, 960 daily data points, 100% accuracy, zero infrastructure cost. It runs on GitHub Actions, and the models, apps and cron schedules are all configurable without code changes.

  • Apple Wallet for YouBiz

    Pushed me the furthest outside my comfort zone.

    An end-to-end native iOS implementation in a codebase I had never touched, with a team I had never worked with. Swift, PassKit, biometric authentication, and the full provisioning flow from iOS Wallet through to the backend. I documented the architecture from first principles so anyone after me could pick it up.

  • API Inspector

    Small, high leverage.

    An on-device HTTP debugging tool that triggers on shake. QA and the rest of the team use it daily.

Outside YouTrip

I worked at Fiserv on PoS machines (ISO-8583) and CBDC, Central Bank Digital Currency, initiatives. I also freelance and contribute to FormVerse, a 3D artifact creation platform for the animation and gaming industry, the first in India.

What people say

A level of proactiveness and ownership I have never seen from a dev in my 8 years in the industry. One of our most reliable FE engineers.
Sebastian, Design Lead
He actively and successfully participated in the exceptionally challenging YT Family feature development, consistently proving he can be trusted to deliver.
Jan, Senior Mobile Engineer

What I care about

I think about systems a lot. Not just code systems, but how information flows, how tools should work, and how to make the right thing the easy thing. That is why this website exists. I own it, Git tracks it, and there is no vendor lock-in and no database to manage.

Right now I'm focused on:

  1. Cross-package architecture, understanding and shaping decisions end to end
  2. Scaling AI tooling beyond FX crawling into test generation, PR review assistance and debugging
  3. Code reviews that help people grow: architectural feedback, not just correctness checks
  4. Getting into system design discussions earlier, not just implementing the outcomes

Outside work

I ride motorcycles. I have a Royal Enfield Meteor 350 and I'm planning for a Harley Sportster S. I travel when I can: recently Singapore, Malaysia and Thailand aboard Royal Caribbean's Ovation of the Seas, with Europe and Iceland planned for 2027. I cycle, and I'm working toward 100km.

I'm going deep into generative AI workflows for developer experience.
