SaaS platform for Jobs made in Replit
I made this SaaS platform for jobs using Replit and Supabase.
It handles user authentication, job postings, submissions, and admin
management, all built with a simple, fast workflow. The platform is fully
deployable, easy to extend, and designed to help users create, track, and
manage job listings efficiently.
Full‑stack developer – AI images & payments
Built an MVP using Lovable.dev (http://Lovable.dev), Supabase, and Stripe that turns 4 uploaded photos into cinematic black-and-white portraits via the OpenAI Images API. Users upload exactly four images, which are validated and processed through an AI pipeline. Unpaid users get watermarked previews; full-resolution downloads unlock via Stripe. Includes a dark, cinematic UI and a “generate another” flow.
Syphe
Syphe is built to automate Tedious Back Office Work for Soloprenures.
We leverage AI to automate Invoices, Emails, Weekly Insights & Calendars for every user so that the creators can focus on creating.
We utilize Stripe connect for Custom Invoices. We've already acquired our first users for Feedback! Protect your business and customer data when using AI Voice Agent
A dental clinic needed a HIPAA-compliant AI voice agent to
automate calls and protect patient data. I built a local voice system with
on-premise STT, ensuring no audio left the clinic. Each booking synced to the
CRM and doctors’ Google Calendars via secure OAuth, with all data encrypted
(AES-256). I added anonymization, 30-day auto-deletion, and audit logs to meet HIPAA. The clinic reached 100% compliance, cut booking errors, reduced staff workload by 70%, and ensured full data privacy and security.
