Selected work

I build new products and make established ones better.

Across writing, healthcare, retail, and engineering tools, I take responsibility for the decisions that turn a product need into working software.

Independent product / macOS and on-device AI

SpellType

Private autocomplete across 10 Mac writing apps.I owned the model, native integrations, and distribution, releasing in about three months. I designed for local inference on an 8 GB Mac without Screen Recording and reached 500+ users without advertising.Shuru Technologies / native iOS fertility care

Olly

Took a native care product from zero to App Store.I moved from Android into native iOS, owned the client in a five-person international team, and reached its first App Store release in about three months.Shuru Technologies / production Flutter POS

Mosaic

Stabilized retail software across 1,000+ locations.I combined customer feedback with telemetry and designed an incremental Flutter migration, reducing fleet-wide ANRs and crashes from several each day to a few each week.Shuru Technologies / web engineering intelligence

GreyMonk

Turned code, delivery, and team data into navigable dashboards.I built TypeScript/React dashboards for a product spanning 100+ engineers and 10+ projects, defining frontend data models and API contracts with backend engineers.

Independent product / macOS / local AI

SpellType

Private autocomplete that stays in the flow of writing.

I built a writing assistant that keeps context on the Mac and works across writing apps. I owned the complete product, from model adaptation and native behavior to public release in about three months.

Inline suggestions in the apps people already write in, with every acceptance under user control.

Production work

Delivering products people and businesses depend on.

I’ve led Android engineers, taken a native iOS product to launch, stabilized a live retail fleet, and built web experiences for engineering leaders.

RailYatri & IntrCity SmartBus / RailYatri (Stelling Technologies) / Sep 2021-Sep 2023

Led engineering across five live Android apps.

I led two developers while staying hands-on and initiated booking and reliability improvements. With one teammate, I implemented nearly all fixes across about 15 findings after the live RailYatri app failed a government security audit, passing reassessment in ten days.

Olly / Shuru Technologies / Oct 2023-Sep 2025

Owned native iOS delivery from zero to App Store.

I moved from Android to native iOS and owned Olly’s first App Store release in about three months, before adopting AI-assisted development. Over about five months in an international team of five, I built medication, appointment, and record workflows, integrating Apple Health and three-language localization.

Mosaic / Shuru Technologies / Oct 2023-Sep 2025

Made a live retail fleet more dependable.

I worked directly with customers and used telemetry to find the failures disrupting store workflows. I designed an incremental Flutter migration that reduced crashes and ANRs while production delivery continued across 2,000+ devices.

GreyMonk / Shuru Technologies / Oct 2023-Sep 2025

Built dashboards that connect code, teams, and delivery.

I built TypeScript/React dashboards that connected code, delivery, team performance, and AI-generated insights to team and project views. I defined frontend data models and shared API contracts with backend engineers so leaders could navigate the activity behind those signals.

Independent products / client to backend

Independent products, built and shipped end to end.

I turn an idea into a complete product: its user experience, underlying systems, and release. Each product uses the technology that fits its users.

Cosmicly

A reflection journal that turns a check-in into useful context.

Shipped on iOS and Android

I built and shipped Cosmicly on iOS and Android, owning the entire system: Flutter clients, APIs, backend, data, astronomical calculations, AI workflows, and subscriptions.

  • Nine structured text and vision workflows over deterministic calculations
  • Complete client, API, data, and subscription delivery
  • Five-language product, release-ready in roughly 2–4 months

A reflection starts with how the person feels, before adding context to the journal.

NoRing

Private call and message protection that users can control.

Shipped Android product / 30 languages

I built NoRing so people can control unwanted calls and messages while keeping their data on the phone. I launched it on Google Play in under a month and continued improving it through 10+ releases in the first three months.

  • 200+ users reached without advertising
  • 10+ production releases in the first three months
  • Local call and SMS protection in 30 languages

    Built and shipped three independent products across macOS, mobile, backend, data, and applied AI, owning product direction through release.

  2. Product Engineer

    Shuru Technologies

    Owned Olly’s native iOS launch, designed Mosaic’s incremental production recovery, and built GreyMonk’s web dashboards and shared API contracts.

  3. Mobile Application Developer (Android)

    RailYatri (Stelling Technologies)

    Led two developers across five production Android apps, initiated booking and reliability improvements, and stayed hands-on through architecture and security work.

Working method

How I take a product problem through delivery.

Take initiative and own the outcome.
I investigate what users and the business need, propose improvements, and take responsibility through implementation, release, and production feedback.
Build the depth the problem requires.
I learn unfamiliar systems, build focused probes, and test the risky assumptions. That understanding lets me choose architecture around the product’s actual constraints.
Lead engineers and stay hands-on.
I coordinate delivery, make technical decisions, and remain close to implementation and debugging. Leading the work includes helping the team solve the hard parts.
Use AI to amplify engineering judgment.
AI accelerates my research, experiments, and iteration across domains. I set the architecture and instructions, verify the work, and own the product decisions and release.
