Built. Shipped. Analyzed.
Deep dives into problem-solving, product strategy, and execution across fintech, AI, IoT, and creative SaaS.
TapQR
Hybrid NFC + QR Fintech Infrastructure
The Problem
Small merchants in India needed a faster, friction-free way to accept digital payments without relying on expensive PoS hardware or dealing with faded, non-scannable QR stickers.
Research
We analyzed payment behaviors across 50+ local merchants. The data showed that scanning took an average of 12 seconds, while tap-to-pay could reduce this to under 3 seconds, significantly improving checkout throughput.
Strategy
Develop a hybrid infrastructure leveraging inexpensive NFC chips embedded within durable acrylic stands that also feature dynamic QR codes as a fallback mechanism.
Design Process
Focused on an ultra-minimal merchant dashboard for real-time settlement tracking. The physical stands were designed to be highly visible, durable, and instantly recognizable on crowded store counters.
Execution
Built the backend with Node.js and the merchant dashboard using Next.js. Piloted the hardware in Stealth with 50+ merchants in New Delhi, processing over ₹2.5M in test volume.
Learnings
Hardware distribution is significantly harder than software. We learned that merchant onboarding needs to be instant; any delay in activating the NFC tag led to immediate churn.
BuildWithDev
AI-Native Product Ecosystem
The Problem
I was shipping multiple SaaS MVPs and workflow systems but lacked a cohesive, centralized ecosystem to demonstrate the compounding value of AI-native automation tools.
Research
Evaluated top-tier developer portfolios and realized that most showcase isolated projects rather than a unified product vision or ecosystem thinking.
Strategy
Create a central hub ('BuildWithDev') that doesn't just list projects, but interconnects them—showing how the output of one AI tool can serve as the input for another within a broader automation strategy.
Design Process
Adopted a stark, brutalist aesthetic using high-contrast typography and bento-box layouts to emphasize technical functionality over superfluous UI decorations.
Execution
Developed a multi-tenant architecture using Next.js App Router, enabling seamless navigation between distinct product MVPs under a single unified authentication state.
Learnings
Building an ecosystem requires strict adherence to design system primitives. I had to refactor early tools extensively to ensure they visually and functionally belonged in the same 'universe'.
Hublix
Smart Home App (IoT)
The Problem
Existing smart home applications in the Indian market suffered from poor localization, complex onboarding flows, and a lack of support for multi-generational households.
Research
Conducted usability testing with older demographics (50+ years). Found that icon-heavy interfaces confused them, and they preferred explicit text labels and persistent state indicators.
Strategy
Design a mobile interface centered around 'Rooms' and 'Routines' rather than individual device controls. Implement a tiered access system for different family members.
Design Process
Created large, highly-tappable card interfaces with distinct active/inactive color states. Introduced a simplified 'Guest Mode' for visiting relatives.
Execution
Prototyped the entire flow in Figma, focusing heavily on micro-interactions for device toggling. Mapped the frontend state architecture to handle real-time WebSocket updates from IoT devices.
Learnings
Latency is the enemy of trust in IoT. If the UI updates instantly but the hardware takes 2 seconds to respond, the user assumes the app is broken. Optimistic UI updates must be handled very carefully.
Veena Studio
DAW Elements & WebAudio
The Problem
Browser-based digital audio workstations (DAWs) traditionally suffered from unacceptable latency and clunky interfaces that frustrated professional musicians.
Research
Interviewed 40+ music producers. The consensus was that while cloud collaboration was highly desired, they would not sacrifice the zero-latency feel of native desktop apps.
Strategy
Build a high-performance audio engine utilizing the Web Audio API and WebAssembly, wrapped in an interface that perfectly mimics the density and precision of desktop software.
Design Process
Developed a complex, dark-mode design system with sub-pixel precision for the timeline, track headers, and plugin interfaces. Emphasized horizontal scrolling and zoom mechanics.
Execution
Implemented advanced Web Audio pipelines, reducing audio processing latency by 35%. Wrote comprehensive user stories and acceptance criteria for the collaborative marketplace systems.
Learnings
Complex web applications require a completely different approach to state management than traditional CRUD apps. We had to build custom event emitters to bypass React's render cycle for audio-critical UI updates.
Cafe Project
Digital Ordering Experience
The Problem
A high-volume artisanal cafe was experiencing massive bottlenecks at the POS during morning rushes, leading to abandoned orders and frustrated regular customers.
Research
Shadowed baristas for three days. Observed that 60% of morning orders were identical repeats from regular customers, yet the POS flow required 4-5 taps to input these standard orders.
Strategy
Implement a hybrid 'Scan-to-Order' system paired with a predictive mobile web interface that remembers past orders and suggests one-tap reordering.
Design Process
Focused on an appetizing, image-forward menu interface with high-contrast typography. Created a frictionless, account-less checkout flow using Apple Pay/Google Pay.
Execution
Designed the end-to-end user journey, from the table-tent QR codes to the digital menu, checkout flow, and the kitchen display system (KDS) for the baristas.
Learnings
In F&B, speed trumps aesthetics. We initially designed a beautiful, animated menu, but stripped out the animations after testing because they artificially delayed the perception of speed for customers in a hurry.
