Web App Security Enhancement - 03/02/2026 00:57 EST

Project: Beta-Stage Web Application Security Setup
Role Needed: Web Application Security Engineer

Project Overview

I’m preparing a coaching-based web platform for public beta and need an experienced professional to implement industry-standard security best practices suitable for handling sensitive user data.

The application is built using a modern low-code/no-code frontend with Supabase as the primary backend and database. Custom SQL integrations via secure APIs are possible if needed.

Objective

Prepare the platform for public beta by implementing professional, scalable security foundations that:

Protect user and client data

Build trust with end users

Lay groundwork for future enterprise compliance (SOC 2 / ISO later — not required now)

Scope of Work (Deliverables)
1. Transport & Data Security

Ensure HTTPS / SSL is correctly enforced site-wide

Verify encryption in transit and at rest

Review Supabase security configuration and recommend improvements

Ensure no sensitive data is stored in plain text

2. Authentication & Access Control

Review and harden authentication setup

Enforce strong password policies

Implement session expiration / timeout handling

Configure role-based access control:

Coaches can access only their own clients

Clients can access only their own data

Admin access follows least-privilege principles

Optional (bonus):

Enable MFA for coaches

3. User Data Ownership & Controls

Implement or verify:

Account deletion (soft delete acceptable for beta)

Basic data export (manual process acceptable)

Ensure strict separation between:

Coach data

Client data

Platform/admin data

4. Privacy & Compliance Foundations

Create or review a Privacy Policy covering:

Data collected

Purpose of data usage

Storage location (cloud infrastructure / Supabase)

User rights (access, deletion)

Beta-stage disclaimer

Ensure GDPR-aligned data handling practices
(No formal certification required)

5. Security Hygiene & Operations

Ensure no hard-coded secrets or exposed API keys

Configure regular database backups (weekly minimum)

Enable basic logging for:

Login attempts

Critical actions (account deletion, role/permission changes)

Out of Scope (Important)

This project does not require:

SOC 2 or ISO 27001 certification

HIPAA compliance or legal documentation

Expensive penetration testing

Over-engineered custom authentication systems

Optional Advanced Task

Advise on or implement secure custom SQL integrations via APIs
(for Supabase replacement or hybrid architectures, if needed)

Ideal Freelancer Profile

Strong experience with web application security

Experience with Supabase, SQL databases, or modern backend stacks

Comfortable working with low-code / no-code platforms

Able to explain security decisions in clear, non-technical language

Experience with beta-stage or early-stage products

Expected Outcome

A secure, public-beta-ready platform

A short written summary explaining:

What was implemented

Any remaining risks

What should be improved post-beta

Timeline

7–14 days preferred (open to discussion)
