Each entry: the problem, the decision I made, who built it, where it runs, and how strong the evidence is.

Photograph a sick plant, get a diagnosis you can act on.
Decision: Require a source link on every recommendation, and judge prompt changes against a fixed golden set, not by feel.
Co-built with Dilpreet Grover · product, eval, orchestration
SourcedA source link required on every recommendation · offline eval result withheld; field accuracy not measured
Product
Your task list, pinned behind every window on the desktop.
Decision: Pin the widget behind every window, not on top of them, and refuse attention: accountless, local-first, no dock icon.

Data
Cohort retention for D2C order exports, computed in your browser.
Decision: Compute every metric in the browser, in a Web Worker: raw order rows never leave the tab, and only aggregates can be saved.

Share the auto you booked; split the fare by kilometres ridden.
Decision: Riders only, driver out of the loop: post-and-join ride sharing, with the owner approving each joiner.

Product
Self-hosted A/B testing whose statistics engine is allowed to say keep running: a sequential verdict instead of a bare p-value, and assignment that puts the same user in the same variant every time. Built solo; evidence so far is a synthetic demo tenant, not production use.

A personal analytics desk for my own Zerodha account, running on my own laptop: technical indicators, Monte Carlo VaR, ensemble forecasting, a NIFTY 500 screener and a FIFO trade journal. Private by design; the tests run on synthetic data only.

Built so a candidate can prepare for the TCS NQT without a paid prep course: 404 practice questions and 10 previous papers (counts per the repo README), quizzes, flashcards and progress tracking. Installable as a PWA and usable offline.

Product
Designed to help solo founders find a co-founder they would actually build with: swipe-based matching shaped around founder-discovery pain points. A two-person build; usage was never instrumented, so there is no user number to report.

Product
Helps a long-distance couple stay in sync when they can't read the room in person. Cycle phase, mood and stress drive daily guidance for her, him and us. Private, used by two people. Privacy is enforced at the database rather than the UI: 575 RLS policy checks, offline-first, hosted on free tiers ($0 a month, self-recorded).

Treated my own portfolio as a product: spec and success criteria before code, then versioned iterations from v1 (Jan 2026) to v6 (Sept 2026), with the decision trail written up as its own case study.

Product
Corporate performance-review theatre, applied to a relationship, entirely on purpose: log a week of small signals and a scoring engine assembles a shareable 12-slide review deck, trajectory and areas of assessment included. The joke is the premise, not the build. A local-first PWA that keeps its data in the browser (IndexedDB); optional sync exists and is off by default.
