React 18 + Supabase Developer — 7 Week Project, Pre-Launch App
We're building a niche professional networking platform. The app is
fully functional and pre-launch — in final hardening phase before
user acquisition begins. The codebase is clean, well-organized, and
fully documented with a detailed spec, prioritized task tracker, and
complete system audit ready to hand off on day one.
No design work. No figuring out what to build. Just executing a
clear, well-defined scope on a modern stack.
Location preference: United States preferred. Will consider
worldwide candidates with excellent English and overlapping
availability with US Eastern time.
STACK
- React 18 + TypeScript + Vite
- Supabase (auth, database, edge functions, RLS, storage)
- Tailwind CSS
- Cloudflare Pages
- TanStack Query + TanStack Virtual
SCOPE OF WORK
Week 1-2 — Backend & Infrastructure
- Migrate Supabase project from Lovable-managed to our own project
- Set up Cloudflare R2 for media storage + custom media subdomain
- Update frontend upload pipeline to point to R2
- Add SMS OTP via Twilio
- Google OAuth integration
- Apple OAuth integration
Week 2-3 — Database Cleanup
- Drop ~20 unused backup and legacy tables
- Add missing indexes on high-traffic tables
- Add proper foreign key cascade behavior
- Tighten RLS policies
- Fix search_path injection risk on existing SQL functions
Week 3-5 — Frontend Code Quality
- Split 6 large components and pages (500-1000 lines each) into
proper subcomponents - Reduce TypeScript any usage across the codebase
- Remove unused npm dependencies
- Guard console statements in production builds
- Extract shared utility functions and constants
Week 5-7 — Mobile
- Capacitor iOS app build + App Store submission
- Google Play submission
Note: App Store and Google Play review times are outside anyone's
control. We understand submission and approval are two different
things.
WHAT WE'RE LOOKING FOR
- Supabase depth — real experience with RLS, migrations, edge
functions, and storage. Not surface-level. - React 18 + TypeScript — comfortable refactoring large components
without breaking existing behavior - Someone who moves fast, communicates clearly, and works well
from a spec without needing everything hand-held - Capacitor experience is a strong plus but not a dealbreaker
- US-based preferred but will consider strong worldwide candidates
WHO THIS IS NOT FOR
- Designers or frontend-only developers
- Developers who need the scope defined for them
- Agencies — looking for an individual contributor only
BUDGET
Hourly. $40-60/hr depending on experience. Open to discussing
fixed price per phase if you prefer that structure.
TO APPLY YOU MUST ANSWER THESE 4 QUESTIONS
Applications without answers will not receive a response.
- Have you migrated a Supabase project before? Briefly describe
what was involved. - Have you set up Cloudflare R2 or similar object storage?
- Do you have Capacitor iOS/Android experience? Be honest —
it is not required. - What is your estimated hours for Week 1-2 alone?
Hey Chance — saw your React 18 + Supabase hardening post.
Full 7 weeks may be more than you want from one person at once.
If Week 1–2 is still open (Supabase migrate, R2, Twilio SMS OTP,
Google/Apple OAuth), I can take that slice as a fixed sprint:
tested PR + short walkthrough, then you decide on later weeks.
I ship backend/integration work in 48-hour fixed packages
($350 standard / $650 complex multi-endpoint). Happy to answer
your 4 questions in a short reply if the slice is still needed.

Hi Chance,
I’m Walter, a US-based senior full stack engineer with over 7 years of experience in React, TypeScript, and Supabase-heavy stacks. Your scope is clear and execution-focused, which fits how I work.
Supabase migration
Yes. I’ve migrated Supabase projects from managed to standalone setups. This included exporting schema/data, reconfiguring auth, rebuilding RLS policies, updating edge functions, and validating storage + API endpoints without downtime.
Cloudflare R2 / object storage
Yes. I’ve set up R2 and S3-compatible storage. Covered signed uploads, custom domains, caching strategy, and secure media delivery pipelines integrated with frontend apps.
Capacitor experience
Moderate. I’ve handled Capacitor builds and app submissions, mostly for React-based apps. Comfortable managing iOS/Android packaging and store submission process.
Estimated hours (Week 1–2)
I am available to start immediately and can work full time (40 hours per week) for your project.
I’m comfortable working from a defined spec, moving fast, and communicating clearly with US ET overlap.
If you want, I can jump on a call and explain my skills and experience in detail.
Looking forward to working with you.
Regards,
Walter
This is a breath of fresh air, Chance. Most projects fail because the scope is a moving target, but handing over a fully documented spec and a "final hardening" roadmap is how you actually get high-level devs to move at light speed.
I’m currently running a project in Tokyo (Tokyo Lore) that highlights high-utility builders and technical architects. Since you’ve already done the hard work of defining the execution logic for this professional network, entering your project could be the perfect way to get more eyes on your "SaaS-ready" infrastructure while your odds are at their peak.
Hi, replying to your React 18 + Supabase post. Up front: I know you want an individual, not an agency. That is exactly what you would get from me, one dedicated senior engineer owning the work, not a rotating team.
Your 4 questions:
Proof I ship production React and Postgres: securityapp.nexworldtech dot cm (multi-tenant platform with paying customers) and settlhome dot cm (live SaaS). I can start this week. Best way to send the spec over?
Hi Chance!
Saw this was posted about 10 days ago — if still open, I'd love to discuss.
Yes, done several — including full migrations from Supabase cloud to self-hosted (data, schemas, RLS, edge functions, storage, auth users). Comfortable with the whole pipeline and validating RLS post-cutover. Lovable → standalone Supabase is a simpler variant of the same workflow.
Not R2 specifically, but built media pipelines on AWS S3 and DigitalOcean Spaces — signed URLs, CORS, custom subdomains. R2's S3-compatible API means the knowledge transfers directly. Setup is straightforward.
No production experience. Happy to ramp during earlier phases so I'm ready when Week 5 hits.
~40-50 hours: Supabase migration (8-12h), R2 + upload repointing (10-14h), Twilio SMS OTP (6-8h), Google OAuth (4-6h), Apple OAuth (6-10h).
Individual contributor, 15+ years of experience. I move fast, communicate clearly, and work well from a spec without needing scope held. Daily stack is React 18 + TS + Vite + Tailwind + TanStack Query; Supabase RLS / migrations / edge functions is a strong area.
If still open, reply here or find me on LinkedIn: /in/alexey-voronkov/
Best,
Alex
I would be glad to explore the opportunity to work with you. We can connect via email at sandra.s@armiasystems.net
Additionally, could you please share your LinkedIn profile?
I look forward to discussing this further.
