Full-Stack Product Builder

Yacov Jacobson

I take software from concept to production: product design, front-end and back-end development, data engineering, AI integration and deployment. I work directly with clients to understand how their business actually runs, then build the system that fits it.

Current projects

What I'm building right now.

01

National real estate data platform (Israel)

A bilingual Hebrew/English property platform built on millions of government sale and planning records, featuring live listings, complete building histories, ranked comparables, 3D building views and a backtested automated valuation model.

02

SellerHub, multichannel e-commerce platform

Re-engineering an online electronics retailer's internal tool into a commercial SaaS product that integrates with Sellercloud and manages listings across roughly 20 marketplaces, including Amazon, eBay and Temu. Live listing tracker, product lister and kit builder, built on Python, TypeScript, React and PostgreSQL with scheduled background processing.

03

CRM and business systems

A sales CRM with role-based access, a dedicated calling interface and automated email campaigns, plus custom systems for a jewelry business, a real estate portfolio and a synagogue's administrative office, replacing paper processes and legacy software.

04

Websites and applications

A mobile app for MK, the kashrut authority of the Jewish Community Council of Montreal (JCC), that layers an AI assistant over MK's entire certified-product database. Grounded in MK's own knowledge and standards, it lets users snap a photo or ask a question and get an instant, authoritative answer. Other builds include custom real estate platforms with full admin back ends and a booking system that assigns rooms automatically.

05

Robotic device-testing system

Leading the project to automate device testing for a phone refurbishment company processing approximately 4,000 devices per day. Managing scope, budget and vendor selection, and coordinating closely with the robotics engineers and automation partners building the system.
