SaaS Developer Needed – Fix & Complete Existing MVP (Vue.js + Laravel, Modular Credit-Based SaaS)

I have a SaaS platform (built with Vue.js + Laravel) that is similar to Instantly, Apollo, and Emailchaser.
The MVP is already developed but incomplete — several core features are only partially built and contain bugs.

I’m looking for an experienced developer (or team) to:

Fix bugs and stabilize the existing codebase

Complete the unfinished MVP features, ensuring they are fully functional

Deliver a stable, credit-based MVP with admin panel support

Treat each feature as its own standalone module/mini-app (so clients can use them independently, or all together)

If the MVP is successfully completed, we will open a new contract to build the full SaaS (new UX/UI, missing features, team management, mobile app, etc.).

Current MVP Features (incomplete, need fixing/completion)

Each feature must be finished, stabilized, and connected to the overall platform:

Email Campaigns → bulk sending, scheduling, templates, unsubscribe handling, credit consumption

Sales CRM / Deal Tracker → leads, pipeline stages, notes, assignments

Chrome Extension → LinkedIn Sales Navigator lead extraction

Email Generator → must integrate with third-party APIs (Hunter.io, email verification APIs, etc.)

Future Features (not part of this contract, but planned for full SaaS build)

Built-in Webmail

Built-in Email Verifier

Email warm-up automation

Team management & collaboration tools

Full credit-based billing system (per feature/module usage)

Redesigned UX/UI

Mobile app (with core features only)

Milestone Structure (MVP Phase)

Each module will be delivered and approved as its own milestone:

Bug Fixing & Code Stabilization

Email Campaign Module

CRM / Deal Tracker Module

Chrome Extension Module

Email Generator Module

Final QA + MVP Delivery

Requirements

Strong experience in Vue.js + Laravel SaaS development

Background in email infrastructure (SMTP, deliverability, DKIM/SPF/DMARC, unsubscribe handling)

Proven ability to integrate third-party APIs (Hunter.io, email verification APIs, enrichment APIs, etc.)

Experience with credit-based SaaS & modular architecture

Comfortable with completing unfinished features + debugging

Good communication & milestone-based reporting

Important

This is a fixed-price project with milestone payments.

An NDA is required before accessing the codebase.

If interested, please provide your ID/passport details so I can prepare the NDA.

Only after successful MVP completion will we proceed with a new contract for the full SaaS build with new UX/UI.

To Apply

Please include:

Examples of similar SaaS projects you’ve built (preferably modular or credit-based apps)

Your Vue.js & Laravel experience

Experience with third-party APIs (email verification, enrichment, Hunter.io, etc.)

Confirmation you’re comfortable signing an NDA
