Sanjay Kr. Singh
Tech Lead | Frontend Architect | React.js, Next.js & AI-Powered Web Solutions
18+ years · Tech Lead & Frontend Architect · React.js, Next.js & AI-powered solutions for businesses that want leads, not just a pretty homepage.
I have spent nearly two decades inside real product teams — shipping interfaces clinics, gyms, startups, and SaaS products rely on daily. The pattern was always the same: a polished sales call, then a junior team, a slow site, and owners left guessing why leads did not come. I started Bitcraftly so you have one senior thread from first message to launch — the same discipline I use for scalable React and Next.js systems, applied to businesses that need trust, speed, and clarity.
Why owners trust Sanjay with their frontend
Sanjay Kr. Singh is Tech Lead and Frontend Architect for Bitcraftly — specializing in React.js, Next.js, UI systems, Core Web Vitals, and AI-integrated web platforms. He has led conversion-focused builds for startups, SaaS founders, agencies, and local brands: SEO-conscious structure, mobile-first UX, written scope before payment, and founder-led delivery from Ghaziabad — serving India-wide and remote clients in English or Hinglish.
- Senior frontend leadership — architecture, build quality, and delivery on one account
- React.js & Next.js chosen for SEO, speed, and code your next developer can extend
- AI-powered features only when they shorten the path to a lead — always human-backed on WhatsApp
- Written estimates and timelines before kickoff — no surprise invoices mid-project
Enterprise-grade frontend discipline · Startup-friendly timelines · Owner-first communication
Not a template shop. Not a bloated agency. A senior architect-led studio for brands that want their website to earn trust the moment someone lands on it.
Main believe karta hoon: website tabhi premium hai jab business ko result de — zyada trust, faster load, clear WhatsApp enquiries. Isliye Bitcraftly par aap seedha founder se baat karte ho, scope likha milta hai, aur delivery par junior handoff nahi.
Why Bitcraftly exists
Generic templates and vague agency promises were costing owners time and money. Bitcraftly is the alternative: a founder-led studio where Sanjay owns the frontend — React or Next.js, redesign, or AI scope — with plain-language updates, premium craft, and a partnership that feels human from Ghaziabad to anywhere in India or abroad.

What we optimize on every engagement
Performance & conversion — built in, not patched later
We treat portfolio work like product delivery: mobile-first layouts, lean page weight, SEO-conscious structure, and enquiry funnels that survive real traffic — especially WhatsApp-first Indian buyers on phones.
Mobile UX
Thumb-first
Layouts tested for small screens first
Lead paths
WhatsApp-ready
Enquiry CTAs above scroll fatigue
SEO structure
Crawlable
Titles, hierarchy, local discovery basics
Stack
React / Next
Maintainable frontends, not locked templates
Mobile-first enquiry paths
CTAs, click-to-call, and WhatsApp placed where thumb traffic actually converts — not hidden in desktop-only menus.
React & Next.js performance discipline
Component structure, image strategy, and route-level SEO — fewer heavy scripts than page-builder stacks.
Core Web Vitals mindset
LCP, CLS, and interaction readiness considered during layout — not “we’ll optimize after launch.”
AI that protects human sales
Bots answer repeat questions; high-intent leads still reach a person on WhatsApp when it matters.

FAQ
Common questions — seedha jawab
Aur sawal ho to WhatsApp par likh dena — English ya Hinglish dono chalega.
Kitne din mein website ready ho sakti hai?
Fast-launch packages: Landing Page in 48 hours, Business Website in 5 days, clinic/gym/coach packs in 5–7 days (content ready hona chahiye). Standard Starter/Professional timelines discovery ke baad likh ke confirm hote hain.
React/Next.js chahiye ya simple website kaafi hai?
Local business ke liye Professional package often enough hai. Startups, SaaS, ya future scale ke liye Premium React/Next.js recommend karte hain.
Kya Hindi ya Hinglish copy site par ho sakti hai?
Haan — headings SEO-friendly rakhte hain, body copy aapki audience ke hisaab se English, Hindi, ya mix.
AI chatbot har site par add karna zaroori hai?
Nahi. Sirf tab jab FAQs, menu, ya lead qualification mein help kare — warna WhatsApp handoff zyada practical hota hai.
Maintenance plan optional hai?
Haan — launch ke baad ₹2,999/month se updates, fixes, aur monitoring available hai.
Ghaziabad ke bahar clients lete ho?
Haan — Delhi NCR (Noida, Gurugram, Delhi, Faridabad) aur poore India + remote international clients; calls/WhatsApp English–Hinglish mix mein comfortable.
Google par Bitcraftly dhoondh sakte hain?
Haan — Google Business Profile par Bitcraftly search karein (Ghaziabad). Reviews aur updates wahan bhi milte hain.
