We're building a SaaS product and need a full-stack developer to add an AI-powered feature to the existing backend.
The platform runs on Laravel. The task is to build a Python service that calls an AI API, processes the response, and returns structured results to Laravel. This is one specific feature with clear boundaries.
What you'll build:
- A Python service using FastAPI
- Connection to an AI API (OpenAI, Claude, etc.)
- API communication between Laravel and the Python service
- Input validation and error handling
- Logging
Flow: Laravel sends data to Python - Python calls AI API - formats the output - returns results to Laravel.
What matters:
- Clean code, no over-engineering
- Clear separation between the two services
- Predictable error handling
- Working production code

We are looking for a freelancer, B2B contractor, small team, or gamedev studio to develop a technical PoC for a deterministic skill-based competitive gaming platform.
The purpose of the PoC is to demonstrate that the gameplay operates without any element of randomness, under identical conditions for all players, with the ability to replay the session, verify player inputs, and prepare technical evidence materials for a regulatory review process.
The scope includes a simple arena or mini-game built in Unity, preferably using Photon Quantum or an equivalent deterministic architecture, input recording, replay/ghost mode, state/hash logging, a fixed map, fixed rules, no RNG, a demonstrable build, and technical documentation.
Required experience includes Unity, C#, multiplayer systems, deterministic simulation, replay systems, lockstep/rollback architecture, or Photon Quantum/Fusion.
An NDA will be required before sharing the full brief. Full IP assignment for the source code, documentation, and builds will also be required.

We are seeking an experienced frontend developer to support the development and integration of an EVM-based decentralized application.
The project involves building secure smart contracts, connecting them to an existing Next.js application, and ensuring that wallet connections, signatures, transactions, events, and contract data are handled reliably.
## Project Tasks
* Develop and update Solidity smart contracts based on provided specifications.
* Integrate contracts with a Next.js and TypeScript application.
* Implement wallet connection, network switching, transaction submission, signature verification, and transaction-status handling.
* Build reusable contract interaction modules using viem, wagmi, ethers.js, or equivalent tools.
* Create deployment and contract-verification scripts.
* Write unit, integration, fuzz, fork, or invariant tests using Foundry or Hardhat.
* Diagnose contract reverts, gas-estimation errors, RPC issues, and wallet-integration problems.
* Review the implementation for security risks, edge cases, gas usage, and code quality.
* Document contract interfaces, deployment steps, configuration requirements, and integration flows.
## Required Experience
* Strong Solidity and EVM development experience.
* Experience with Foundry or Hardhat.
* Experience integrating smart contracts with Next.js and TypeScript.
* Knowledge of viem, wagmi, ethers.js, wallets, signatures, events, and token standards.
* Understanding of access control, contract security, transaction lifecycle, and testing practices.
* Ability to produce maintainable code and clear documentation.
Experience with DeFi, attestations, registries, decentralized identity, account abstraction, or upgradeable contracts is helpful.
## Deliverables
* Completed Solidity contracts and application integrations.
* Automated test coverage.
* Deployment and verification scripts.
* Technical documentation.
* Source code submitted through the agreed repository workflow.

Zlecę stworzenie skryptu, który przez oficjalne API Allegro będzie codziennie wyszukiwał popularne, ale wyprzedane/zamknięte oferty w wybranych przeze mnie kategoriach.
Działanie bota:
Pobiera listę aktywnych ofert ze wskazanych kategorii i zapisuje w bazie te z wysoką sprzedażą (np. >50 sztuk).
Przy kolejnym skanie sprawdza ich status. Jeśli oferta została zamknięta lub stan spadł do 0, skrypt to wychwytuje.
Generuje codzienny raport (Excel/CSV) z listą tych produktów.
W raporcie potrzebuję: Nazwa przedmiotu, Kategoria, Kod EAN (GTIN), Cena oraz liczba sprzedanych sztuk przed zamknięciem.
Proszę o podanie ceny, czasu realizacji oraz informacji o doświadczeniu z API Allegro.
