About
I'm a tech lead and senior software engineer with over seven years building and scaling products across Android, iOS, and Web. I joined Quantum Coherence as the founding engineer, shipped the first product from an empty repository, and grew from leading frontend into owning backend, infrastructure, and architecture. I now lead all engineering there and manage a team of four.
That widening scope is the throughline of my work. I started in Flutter, took on Node and MongoDB alongside the CTO, moved into AWS and Azure infrastructure, and picked up Python when we built our AI chatbot. I like the parts of the job where architecture meets delivery: systems a team can move quickly in, release pipelines that make shipping unremarkable, and the review culture that keeps both honest.
Alongside that I'm the founder of Vobbin, an AI health coach live on iOS and Android, where I built the product and lead engineering end to end. I also created and maintain Fabrik, an open-source Flutter toolkit adopted by other engineering teams.

Joined as the founding engineer and built the first product from scratch. Grew from leading frontend into owning backend, infrastructure, and architecture, and now lead all engineering at the company.
What I did (10)
- Founding engineer: built and shipped the company's first Flutter app to Android, iOS, and Web, establishing the engineering foundation from an empty repository.
- Now lead all engineering as Tech Lead, owning architecture, infrastructure, and deployments across multiple products, and managing a team of 4 developers.
- Worked directly with the CTO on backend from the start (Node, MongoDB, AWS), widening from frontend lead into full-stack and platform ownership.
- Built an internal admin panel in Flutter Web, giving the team self-serve control over content and operations.
- Led frontend and the frontend team for the company's second product, while taking on a growing share of backend design and delivery.
- Integrated an AI chatbot across both apps, then took on development of the chatbot service itself (Python, Azure, AWS).
- Built high-performance audio/video streaming players forming the core of the product experience, plus real-time video calls, analytics, and engagement tools.
- Scaled products to 50K+ users and 4.7★ ratings by driving data-informed decisions with Mixpanel and Amplitude for engagement and RevenueCat for subscription revenue.
- Established CI/CD pipelines (GitHub Actions, Fastlane, Codemagic) for automated testing and multi-environment deployments.
- Run bi-weekly release cycles with <24-hour bug turnaround by applying DDD and SOLID principles, and enforce code quality through PR reviews.

Vobbin
An AI health coach that connects biology, nutrition, and fitness.
- Both stores
- iOS + Android
- Wearable supported
- Any
- Pillars in one model
- 3
Sleep, nutrition, and training are one system, but most apps track a single pillar and stop. Vobbin connects all three, so its coaching accounts for the state you're actually in today.
Details
Most health apps solve one pillar and stop there. Your sleep affects your recovery, your recovery affects your workout, your workout affects your hunger, and your nutrition affects your energy, but a sleep tracker can't see any of that.
I founded Vobbin and built most of it: the cross-platform app, the data pipeline that normalizes wearable and manual inputs into a single picture of a user's day, and the AI coaching layer that turns it into a clear answer to "what should I do today?" My co-founder Pooja joined later and works across tech, product, and marketing.
- Live on both the App Store and Google Play, shipping regular releases.
- Integrates any wearable rather than locking users into one ecosystem, normalizing sleep, recovery, strain, stress, vitals, nutrition, and cycle data into one model.
- Coaching adapts to the user's depth: plain guidance for beginners, full metrics and trends for people who want to inspect the why.
- Built privacy-first: health data powers coaching only. No ads, no selling, no sharing.

Fabrik
A modular Flutter toolkit for clean, scalable apps.
- Packages on pub.dev
- 7
- Pub points, every package
- 160/160
- Downloads
- 8k+
A CLI that scaffolds Flutter features using DDD layered architecture, plus six focused packages. Saves teams 2-3 days of setup per project and keeps architecture consistent as the codebase grows.
Details
Every new Flutter project re-solves the same problems: a theme system, responsive breakpoints, form state, error types, a snackbar that doesn't fight the design system. Teams either rebuild them or copy them between repos, and the patterns drift apart.
- Seven packages on pub.dev, each scoring a full 160/160 pub points, with 8k+ downloads.
- Adopted by multiple engineering teams to standardize setup, accelerate onboarding, and cut boilerplate.
- fabrik_theme (design tokens, typography, color), fabrik_layout (responsive breakpoints), fabrik_forms (UI-agnostic form state and validation), fabrik_snackbar, fabrik_utils, and fabrik_result (Either/Unit for type-safe error handling).
