Best filtering: Qdrant
Best hybrid search: Weaviate
Best for prototyping: Chroma

📊 6/ Evaluation matters!

On our real-world test set of 56 messages:
• F1 score: 0.899
• Precision: 0.969
• Recall: 0.838
• False-positive rate: 5.3%
These are prototype results on a small test set, not a guarantee of real-world accuracy.

🧩 I built an Image Mosaic Generator that recreates photos using tiny cartoon animals, LEGO bricks & more! 🎨

Built with Python, NumPy, KD-trees & CIELAB color matching.

Got this back from the client today: "She brought our legacy business into the digital age smoothly and professionally." — Anil Jadhav, Smart Art proprietor. First real client, first real testimonial. Feels different than a GitHub star.

Handed it off to the client, who'll publish it on her own domain. Recording a full walkthrough next. First real client project, first real lesson: understand the customer before you write a line of code.

This is the first project I've built for a real external client instead of myself. The hardest part was never the React, it was figuring out what a 30-year offline business actually needed versus what a checklist says a website should have.

Content layer: 8 SEO-researched blog articles (Warli art, industrial floor marking, epoxy coatings), a 59-image gallery across 7 categories, full JSON-LD structured data and per-page meta tags generated programmatically.

[Preksha_Dewoolkar @prekshaaa2166]

Contact form: dual-channel submission (Google Sheets via Apps Script + WhatsApp), phone validation regex for Indian mobile numbers, live character counter. No backend server to maintain, and the owner can open a spreadsheet himself.

[Preksha_Dewoolkar @prekshaaa2166]

Made it a full PWA: service worker, offline caching, installable manifest, push notification support. Most of this business's customers are on mobile data, not desktop broadband, so this isn't a nice-to-have.

7 custom hooks doing real work: throttled scroll tracking, intersection observers powering every scroll-reveal, debounced search, a localStorage sync hook, reactive media queries. Not boilerplate, actually load-bearing.

Just wrapped building a full production website for a real client: Smart Art, a 30+ year industrial art & signage business in Thane run by artist Anil Jadhav. Siemens has been a client since 1990. No spec doc, no PM. Thread on what I built 🧵

[Preksha_Dewoolkar @prekshaaa2166]

Stack: React 18, React Router 6, Framer Motion for transitions, React Helmet Async for per-page SEO, React Markdown for blog rendering. 9 pages, 32 components, lazy-loaded with code splitting to stay fast on mobile data.

[Preksha_Dewoolkar @prekshaaa2166]

The real constraint wasn't technical, it was that customers order over WhatsApp, not forms. So the site routes straight to WhatsApp for ordering instead of a contact form nobody would use. Build for how people actually work, not what looks impressive.
