Every post is grounded in shipped work: real architectures, real metrics, and honest failure modes.
Same format, new numbers — real before/after, no fluff.

17 boring fixes beat one big redesign. Weekly micro-forensics on checkout, forms and search — each measured — compound faster than a quarterly splash.
A field-by-field form teardown with GA4 events and Clarity — one restrictive field caused 23% of drop-offs. The fix raised submissions +124% in 28 days.
Named after Feluda's assistant, Topshe runs Qwen 2.5 in-browser via WebAssembly — wake word, research and planning tools, zero data leaves.
TGB Hunt: a self-hosted, open-source agent that finds recruiters, drafts intros, and never sends without my approval. 766 commits, GPLv3.
Building a calculator where SIP/EPF/PPF/NPS and FIRE are first-class citizens — product choices from projections to inflation. Design, scope, and tests.
The method behind the Sierra checkout teardown: instrument the funnel first, form ranked hypotheses second, never optimize an unmeasured funnel.
A dormant 'Send Greetings' feature, an image-gen model, and a festival calendar across 27 occasions — feature engagement up 168% at LiveKeeping.
Why PRO+ users generated bills in Tally, not in-app — a two-week diagnostic that uncovered a 17:1 gap and changed the roadmap at C-suite level.
A Google Apps Script pipeline unifying Kibana, MongoDB, and GA4 into one auto-populated report — what white-collar automation really costs.
At Upcore I ran 20+ prospect interviews across 12 verticals; the output was a prioritized opportunity brief with top-3 use cases.
Designing a notification system across renewals, transactional states, and conflict logic — with priority tiers and a daily cap users don't hate.
A 2,200-film dataset, gradient-boosted ML plus Bayesian priors, and a scoring engine that backtests itself. I built FilmRisk.AI — the failures included.
Story-led category journeys beat commodity grids: +17% PDP clicks, +34% qualified leads, −16% bounce in a 4-week sprint at Sierra.
Sierra routed every lead the same way until the data said otherwise: web forms 63.5% CVR, cart abandonment 0.4%. A tiered router fixed the queue.
A 480K-session teardown: three separate checkout problems hidden behind one dashboard number, three targeted fixes, two sprints — −26% abandonment.
