I am looking for a full-stack developer to build a Web Compliance Audit platform. The goal is to create a solution that scans websites for GDPR, Privacy, and Cookie compliance using AI (OpenAI API) and generates professional audit reports. The front-end will be WordPress (for user management, payments, and UI), while the "brain" will be a Python-based engine running on a Linux VPS. Key Features & Requirements: 1. WordPress Frontend: Landing Page: Professional UI where users can enter a URL for a "Quick Scan." User Dashboard: Where clients can see their scan history and download PDF reports.

I’m building a general-purpose web application with a strong focus on clean front-end interactions and a reliable back-end architecture. The technology stack is intentionally simple and practical: TypeScript on the client side and Python on the server side. I handle product direction and overall architecture, and I’m looking for a Russian-speaking freelance developer who can work as a true full-stack partner. The work spans the entire stack—one day refining a React component, the next implementing a FastAPI endpoint, and occasionally helping shape core backend workflows. What I’m looking for Strong experience with TypeScript and modern front-end frameworks such as React, , or similar, along with current tooling and best practices. Solid Python skills and hands-o...

I need a backend engineer to turn my spec into an MVP that exposes a clean, API-first trust and reputation service for autonomous AI agents. The entire product lives server-side—no front-end work at all—so every feature must be reachable through intuitive, well-documented endpoints. Core requirements • Stack: your choice of FastAPI (Python) or Node (TypeScript), backed by Postgres, containerised with Docker, and wired to Stripe for billing events. • Auth: simple, robust API Key flow; keys must be generated, stored, and validated on every request. • Scoring logic: compute each agent’s trust score solely from its interaction history, according to the formulas in the spec. Performance metrics or direct user feedback are outside this first iteration. ...

I need a skilled full-stack developer to create a web-based minimum-viable product that helps users manage their personal finances.

I need a coder who already feels at home working with large-language-model frameworks to build a text-generation program that will power customer-service chatbot replies. The goal is straightforward: feed the bot a user query and receive a clear, helpful response that sounds natural, stays on-brand, and can be deployed inside our existing support interface. Core needs • Model handling: Need to use offline LLMs, preferably llama 3/opus and gemma as long as latency and accuracy stay competitive. • Prompt/response logic: craft the prompt pipeline so it captures context (conversation history, customer metadata) and returns concise answers without hallucinating policies or numbers. • Safety & tone controls: integrate guardrails for profanity, personally identifiable in...

I need a web platform that blends a full-featured job board with a LinkedIn-style professional network while keeping user data exceptionally secure. Job seekers should be able to search, filter, and apply for roles, yet also build profiles, connect with peers, follow companies, and exchange messages—all behind strong authentication and encrypted data storage. The build has to feel modern and responsive on desktop and mobile. I’m open on the stack, but I do expect industry-standard security practices (HTTPS everywhere, hashed passwords, role-based access, and protection against common exploits). Admin tools for posting jobs, moderating profiles, and viewing analytics must be included. Because I’d like the first production-ready release in roughly four weeks, I’m lo...

A streamlined WhatsApp chat solution written in Python is the goal. The code will live on my Ubuntu 22.04 VPS and must let me programmatically send, receive, and log WhatsApp messages from an existing Business account. Reliability comes first; every outbound message needs an acknowledgement callback and every inbound message should be captured in a local SQLite or PostgreSQL table for later reporting. Scope highlights • Clean Python 3.x code that wraps the official WhatsApp Business Cloud API (or another compliant gateway if you can justify it) • Simple CLI or minimal Flask/FastAPI endpoint to trigger messages with parameters: recipient, template/body, media (optional) • Webhook listener that records incoming messages, delivery receipts, and errors to the database and...

I need a production-ready search stack that starts with an ETL flow pulling exclusively from our internal PostgreSQL databases. The pipeline must ingest and transform 38 000+ B2B category records and 5 000–10 000 company profiles, then run cleaning, vectorization, and enrichment steps so every record is categorized and stored in a pgvector-enabled schema. Once the data is in place, a separate microservice should expose a REST API that supports hybrid search: dense vectors (OpenAI text-embedding-3-small) combined with BM25 and blended with RRF scoring. Results have to work equally well in Hungarian and English; huspacy, spaCy, and Open AI are the preferred tools for language handling and any fallback generation. I expect the codebase in Python 3.10+, organised as two deployable unit...
