Mohammad S. - Remote full-stack developer

Mohammad S.

Senior Full-Stack Engineer, React/Next.js/Supabase
Based in: 🇹🇷 Turkey
Timezone: Istanbul (UTC+3)

About

I take over existing web products that are stuck, find the real blockers, and get them to a stable release. Senior full-stack, strongest in React, Next.js, TypeScript and Supabase/Postgres, with Node.js, AWS and React Native in production.

Typical work: auth and RLS problems, data migrations, payments, API integrations, inherited codebases nobody wants to touch, and AI features that need to be reliable rather than impressive.

Selected work:

• ACE Dashboard: LinkedIn outreach automation platform (Next.js, Supabase). Built the dashboard, content calendar and approval workflows now running in production.

• Forward Thinkers / The Brain: AI reporting system that produces client reports from business data, with retrieval, claim-level source evidence and human approval before delivery. Multi-tenant, PDF output.

• Members-only platform (Arc client): repaired a failed Aurora MySQL to Supabase migration, restored 1,643 user accounts without data loss, fixed auth, magic links and payments.

• Meet Your Mind: migrated from Lovable Cloud to client-owned Supabase and Cloudflare, then assessment and dashboard improvements.

• Left Hand Seat: flight-school directory with Next.js, Supabase, Stripe and map search.

• Lost Paws: ongoing engineering for a UK pet-microchip platform (registration, transfers, third-party integrations).

• Aitopia: React Native AI app with streaming responses, auth, chat history and automated tests.

How I work: written scope first, early risk flags, small reviewable changes, staging verification before production. Structured AI-assisted workflow with engineering review and tests kept central.

Projects

ACE Dashboard | LinkedIn Sales Operations & Automation
TypeScript
Next.js
Supabase
N8n
Built a sales-operations dashboard that brings LinkedIn lead qualification, outreach workflows, content planning, and human approvals into one product. My work spans the product interface, Supabase data layer, n8n/Unipile workflow integration, and production hardening. The application includes pipeline tracking, content calendar and review workflows, an inbox, lead management, and configuration controls. Made automation observable and controllable through clear approval states, reliable data loading, webhook diagnosis, and checks across the interface and backend workflows. Recent production validation covered content loading, calendar views, navigation, and responsive layouts. Stack: React, Next.js, TypeScript, Supabase/PostgreSQL, n8n, and Unipile. Screenshots: live dashboard overview and content calendar. Contact names and unpublished content are redacted; displayed counts and states are unchanged.
Forward Thinkers | Evidence-Grounded AI Reporting
TypeScript
Next.js
OpenAI
Supabase
N8n
Architected and built The Brain, a multi-tenant AI reporting platform that turns connected business data into reviewable reports and evidence-grounded answers. Owned the Next.js product interface, Fastify API, Supabase/PostgreSQL data layer, and integration contracts for n8n ingestion. The system combines structured metrics with document retrieval and presents report coverage, confidence, and source evidence to reviewers. Engineered safeguards against unsupported AI output: claim-level citations, structured validation, deterministic fallbacks, and data-quality gates. Reviewers can inspect the stored source value, baseline, reporting period, and collection timestamp behind a claim. Approved reports are frozen, with human approval and PDF export built into the workflow. Stack: Next.js, TypeScript, Fastify, Supabase/PostgreSQL, pgvector, OpenAI, n8n, Vercel, and DigitalOcean. Screenshots: the deployed reporting app's report-review screen and claim-level evidence drawer. The linked deployment is staging-hosted and requires authentication.
