Selected work

Products I designed, built and shipped myself, from database to deploy. Each one has a live link or a walkthrough on request.

SaaS · Real estateBuilt · pre-launch

Penga

AI lead management for real estate agencies in Dubai and India. It sits on top of the CRM they already use.

  • Manager dashboard. An Attention Queue of leads going cold, a lead status board, a queue for failed audio and GCI metrics per agent.
  • WhatsApp voice-note pipeline. Agents send a voice note after a call. It is transcribed with Deepgram and Groq, and a three-layer fuzzy matcher finds the right lead from a spoken name.
  • Priya, an AI voice agent. Built on Vapi, she calls new leads and returns a structured summary the dashboard can sort.
  • Multi-tenant by design. Supabase row-level security keeps every agency's data apart, checked in a seven-phase production audit.

Saarthi

Rent scooters, bikes, cars, EVs and cycles from local shops in Mount Abu and Goa.

  • Search like a text. Type “bullet in Goa this weekend under 1k” and get matching rides, or use the classic form.
  • One honest price. Rent, add-ons and GST in a single total, with the refundable deposit shown on its own.
  • Proof photos. A guided, timestamped walk-around at pickup and return, so nobody is blamed for old scratches.
  • A deposit you can watch. Held, inspected, released, credited, with every deduction itemised.

Dayline

A day planner that puts everything on one timeline. Installable on phone and laptop.

  • Today at a glance. A strip from 06:30 to 23:30 shows booked and free time, with what's up next and a countdown.
  • Plan by the week. A live now-line, free gaps labelled by length, and an Auto-fit tray that slots tasks into the gaps.
  • Ask. An AI planner that sees today, the inbox and routines. It proposes changes, and nothing moves until you tap Apply.
  • Sign in with an email code or Google. Lists for college, work and personal life.

Website redesigns

Precision Star

An MEP contractor in Deira, Dubai. Their current site is a simple template: a headline, stock photos and three pages.

  • Built around the trade. A blueprint hero draws ducts, cables and pipes through a building section.
  • Trust up front. A licences and approvals panel for Dubai Municipality, DEWA and Civil Defence.
  • Easy to contact. Quote requests, click-to-call and WhatsApp on every screen.

The Royal Residency

A hotel, the AROMA restaurant and a 1,200-guest banquet hall on G.T. Road, Aligarh. I pitched two directions.

  • Booking first. Check-in, check-out and guests sit in the hero, with WhatsApp one tap away.
  • Local in voice. Sections named Swagat, Vishram, Bhoj and Utsav, with Hindi set beside the English.
  • Two moods. Nawabi in ivory and gold, or Royal Maroon for evenings and weddings.

LPU Find

Lost and found for Lovely Professional University's campus, built for the phone in your pocket.

  • Post in seconds. Lost or found, with a photo, category and exact spot such as “Library, 3rd floor quiet study”.
  • Match strength. Posts are paired and labelled Strong or Possible match, and urgent items stay pinned on top.
  • Campus-aware. Filter by campus, by lost or found, and save posts to check later.

About

I'm Prakhar, a developer from Aligarh and the founder of Penga. I build complete products on my own: the database, the backend, the interface and the deploy.

I ship fast with AI-assisted development, using tools like Claude Code and Antigravity, and I stay in control of the code. I plan the architecture, review every change and can explain any line I hand over. Alongside client work, I'm studying B.Tech CSE at LPU and interning as a full-stack developer at Syncgaze.
