# Full-Stack Developer Needed – Take Over, Complete & Launch Custom Finance CRM ## Project Overview I'm looking for an experienced, reliable full-stack developer to **take full ownership of completing and launching an existing custom CRM application** for an Australian financial services business. The application is approximately **75% complete**, built using AI Studio within GoHighLevel, with Supabase as the database and Mailgun for email functionality. I've developed the application to its current stage, but it's taking up too much of my time, and I'm now looking to hand over the remaining development entirely to a capable professional. **I am not looking to continue developing the application myself.** I need someone who can independently manage the re...

Project Overview: We are building a multi-tenant B2B SaaS platform that dynamically generates, signs, and distributes secure, encrypted data archives (.zip variants) based on user input. We are currently in stealth mode and will share specific business logic upon signing an NDA. Key Responsibilities: • Develop a multi-tenant backend engine that takes JSON inputs and assets from a relational database and compiles them into cryptographically signed file packages. • Implement secure cryptographic file signing workflows using server-side certificates (.p12/OpenSSL). • Build out a robust asynchronous worker queue to handle real-time HTTP/2 server-to-client push updates at scale. • Develop a responsive web dashboard for business configuration and a mobile-friendly web viewer ...

Founding Engineer / Product Builder (Equity + Performance Upside) — Habibot Habibot is a chat-first booking assistant: discover a place, understand the menu and atmosphere, request a booking, receive a real answer, and get a reminder — no app download required. Telegram is the first live channel. WhatsApp, voice and Calendar are subsequent channels, only when their provider, privacy and reliability gates are genuinely ready. This is not a greenfield build. The active product is a substantial Python codebase built around aiogram, async services, SQLAlchemy/Alembic, booking logic, discovery, menus, notifications, multilingual chat and a signed audit ledger. A legacy Bun/TypeScript MVP remains for selected WhatsApp, calendar and identity pieces. I’m looking for someone who c...

I need our database layer re-designed so that records load faster and more reliably through the web application. The focus is squarely on improving data accessibility: queries must return results quickly, and common user actions should no longer be blocked by heavy reads or locking issues. Work begins with an audit of the current schema, index usage, and query patterns. From there, produce an optimized structure, add or adjust indexing, and recommend any caching or sharding techniques that match the projected growth of our data set. Wherever possible, keep the solution portable across standard relational engines (PostgreSQL or MySQL are most relevant right now) and cloud hosting environments. Acceptance criteria • Revised schema and index scripts in executable SQL. • A concis...

I’m putting together a fundamentals-level SQL program for an international group of beginners and I need an instructor who has real-world experience writing queries day-to-day. The goal is to walk participants through core concepts—tables, SELECT statements, WHERE, JOIN, GROUP BY, simple subqueries—so they leave confident enough to explore data on their own. All sessions will be delivered live online in English, so you should be comfortable presenting over Zoom or a similar platform, fielding questions on the spot, and adapting your pace if the group needs extra clarification. I will handle scheduling and participant logistics; you bring engaging explanations, clear slides, and practical demos that work on any standard SQL engine (MySQL, PostgreSQL, SQL Server, or SQLite...

I’m looking for someone who can wear both hats—project manager and hands-on developer—to drive a new web application from concept to production. We are looking for a project manager/developer (Claude Code) to lead a short V1: a tablet data-entry app that feeds a database we own, and mirrors the data to our existing Google Sheets. Context We import and distributes poultry feed premixes and concentrates. About 80% of sales are wholesale, to around sixty resellers, and 20% retail. • Points of sale: two retails shops, 5 warehouses. 10 products. • Management: the owner runs the business remotely from Montréal. Today, all data lives in one large Google Sheets file. It has become slow and fragile, and anyone with access can change it without a trace. For rem...

I’m building a reseller-facing dashboard for my Whop AI store and I need it to focus solely on analytics and reporting. The interface should surface two core data streams: customer demographics and product usage statistics. For the demographic slice, I care about grouping users by purchase history—first-time buyers, repeat customers, high-value orders, subscription renewals and similar cohorts. Age, gender or location can wait, but please leave room in the data model so they can be plugged in later without rewrites. I want a clean, responsive UI that loads quickly, presents headline KPIs at a glance and lets me drill down into tables or charts. Real-time or near-real-time data refresh, simple filter controls, and CSV/Excel export are all essentials. Feel free to choose the tec...

Project Overview We are seeking an experienced Full-Stack Developer or Development Team to design and build a modern, AI-powered, multi-tenant web application for commercial driver recruiting, pre-qualification, application processing, and onboarding readiness.

The application must be highly customizable, scalable, mobile-friendly, intuitive, and designed to minimize manual data entry.

Our online education portal, , is powered by Python—primarily Django with a couple of small Flask services—and everything funnels through a single PostgreSQL instance. Traffic and course data have grown quickly, and the database layer is now the clear bottleneck. What I need is a specialist who can dive into our existing REST-driven codebase, profile the slow spots, and leave us with a noticeably faster, more stable platform. You’ll be looking at query plans, indexes, connection pooling, and any ORM patterns that might be hurting us. If you prefer working directly in SQL rather than through Django’s ORM when performance calls for it, that’s fine; the end goal is speed and reliability. While the stack is firmly Python/PostgreSQL, I’m open to discussing...

I’m building a desktop-first retrieval-augmented generation (RAG) tool and I need a senior Python engineer to take full ownership of the document-ingestion layer. The current prototype already embeds and queries local language models, but the pipeline that feeds them is still thin. Your focus will be to ingest and normalise three document types—plain text, PDFs, and Word files—so they can be chunked, vectorised, and indexed reliably. Here is the landscape you’ll be stepping into: • Stack: Python 3.11, LangChain, FastAPI, SQLite for local mode, Postgres in the cloud, Git for workflow, and a mix of GGUF local models plus an OpenAI fallback. • Environment: Windows is the primary target, so you should be comfortable with PyInstaller or similar packaging to...

Project title: Independent human code review of a Node/React/Postgres web app (auth, permissions, API, data layer) Skills: Node.js, Express, PostgreSQL, React, Security Review, Code Review Description I’m looking for an experienced software engineer to do an independent review of a web application before it goes live with its first real users. This is a quality review of the critical paths. It is not a security pen test or a certification. AI reviews are already done. I need a human. The codebase has already been through a series of AI-assisted, read-only reviews covering structure, security, maintainability, database, performance, and UI. Those findings are being worked through. What I need now is an experienced human engineer’s judgment: confirm what matters, catch what auto...

Project Title Develop a QR-Based Instant Document Printing Platform for Multiple Shops Project Overview I am planning to launch a QR-code-based instant document printing network in Hyderabad, India. The objective is to install printing facilities at multiple existing shops, allowing customers to upload documents from their mobile phones, pay online and get their documents printed instantly. Customers should not need to install a mobile application. They should simply scan a QR code displayed at a shop, open a mobile-friendly webpage, upload their documents, select printing options, make payment and collect their printouts from the respective shop. Initially, the network will have 10 locations, with a combination of company-owned and partner-owned printers. The platform should be desig...

I have a batch of PDFs that contain only plain-text content. Every word from every page needs to land neatly in a single SQL table—no images, no form fields, just raw text. Here is what the finished job looks like to me: • A script (Python, Java, or similar) that reads each PDF, pulls out the complete text, and writes it into a table such as `pdf_text` with columns like `id`, `file_name`, `page_number`, and `text_block`. • A SQL file that creates this table and lets me recreate it easily on MySQL or PostgreSQL. • Clear instructions so I can rerun the process whenever new PDFs arrive. Accuracy is critical: the stored text must perfectly match the source PDF, page by page. If you prefer libraries such as PyPDF2, PDFMiner, Tika, or pdftotext, feel free—as l...

I need my application wired to a back-end database so that every new or changed record is reflected instantly on the front-end dashboards. Real-time updates are the only reporting style I will accept; batch or scheduled exports will not meet the requirement. The core work involves: • Connecting the chosen data store to my existing codebase (language-agnostic at this stage; you may recommend SQL, NoSQL, or an in-memory solution after reviewing my load profile). • Building the live data pipeline—triggers, change streams, or pub/sub—as appropriate. • Rendering the real-time views in a lightweight reporting layer so end-users see changes within seconds. • Supplying clean, well-commented code and a short deployment guide that lets me reproduce the setu...

I’m building a lightweight yet secure online service that lets private individuals move money across borders with ease. The whole focus is personal use—not corporate payments—so the user journey has to feel friendly, fast, and transparent.

I have a batch of unstructured PDF documents and want every piece of text inside them pulled out and inserted into an SQL database. I do not need the original layout, fonts, or styling—just clean, plain-text content mapped to sensible fields (e.g., file name, page number, extracted text). Your task is to create a repeatable workflow or script that: • Reads each PDF, handles multipage files, and copes gracefully with occasional scan-quality variations. • Outputs the raw text into an SQL-ready structure and populates a database I can query immediately after the job is done (MySQL or PostgreSQL are both fine—I’ll match whatever you choose). • Includes clear setup instructions so I can run the process again on new PDFs without extra help. Accuracy o...
