I need a full-stack developer who can take my concept for an online crypto casino and turn it into a production-ready website, then wrap the same codebase into a lightweight mobile app without blowing up the budget.

Core game offering
The site will launch with Casino games only—specifically Slots, Blackjack, and Roulette—so please come prepared to handle random number generation, fairness proofs, and attractive front-end animations for all three.

User accounts & security
Registration must include Two-factor authentication (email/SMS or an authenticator app). Each account will have an on-site balance plus a connected crypto wallet (MetaMask and WalletConnect support to start). Users should be able to move funds freely between the wallet and their casino balance with clear transaction logs.

Pool creation & voting
Players can create wagering pools; others vote to join using on-chain signatures. Once a pool fills, the game launches automatically. I’ll provide detailed pool rules—you wire up the voting logic, smart-contract interaction, and basic admin controls so I can tweak fees or limits later.

Leaderboard & stats
A real-time leaderboard (top winners, biggest multipliers, etc.) drives engagement. I want this fed by live game data and reset intervals I can configure from an admin dashboard.

Cost-efficient app build
After the site is stable, package it as a cross-platform app (React Native or Flutter PWA is fine; I’m open to suggestions) so we avoid rebuilding features twice.

Deliverables
• Responsive crypto-casino website with Slots, Blackjack, and Roulette
• Secure 2FA user system + crypto wallet integration
• Pool creation module with on-chain voting
• Live leaderboard and stats dashboard
• Cross-platform mobile app build from the same codebase
• Clean, well-documented code and deployment guide

Acceptance criteria will be simple: if I can install, run, and play the three games end-to-end—including wallet deposits, pool votes, and leaderboard updates—you’ll get sign-off. Let’s keep communication tight and milestones small so we stay within a lean budget.

We're looking for a sharp, go-getter Web3 Social Media Manager to own and grow our presence on X (Twitter) and Instagram for a major multi-city blockchain and AI event series running in 2026.

This is not a scheduling-and-posting role. We want someone who lives and breathes Web3 culture, understands what makes crypto Twitter tick, and can grow a following aggressively while managing influencer campaigns across 10 cities.

If you've watched a project go from 2,000 to 50,000 followers and you were the one who made it happen; we want to talk.

What You'll Own

Content and Community:

- Own the content calendar for X and Instagram end to end
- Create and post daily content - threads, reels, stories, spaces, memes, live updates
- Build and grow community engagement - replies, quote tweets, comment sections
- Cover events live from the ground across multiple cities (remote coordination with city teams)
- Write copy that sounds like a human, not a brand

Growth:

- Grow our X and Instagram following significantly
- Identify growth levers specific to Web3 Twitter and crypto Instagram
- Run giveaways, contests, and engagement campaigns that convert to real followers

Event Coverage:

- Coordinate with city teams for real-time content during events
- Post live updates, speaker quotes, crowd moments, and behind-the-scenes content
- Turn every event city into a trending moment on crypto Twitter

What We're Not Looking For

- Someone who will schedule posts and call it social media management
- Generic content creators without Web3 knowledge
- Anyone who measures success in impressions instead of followers and engagement
- Agencies or teams - individual freelancer only

Deliverables

- Weekly content calendar submitted every Monday
- Daily posting on X and Instagram - minimum 2-3 posts per platform per day during event weeks
- Monthly growth report - follower count, engagement rate, top performing content
- Influencer campaign tracker updated weekly
- Post-event content summary for each city

• Two social media accounts you managed for Web3 or crypto brands — show us the follower growth numbers with before and after

I’m building a brand-new e-learning platform and need a developer who is comfortable working natively on both iOS and Android. My priority is solid, platform-specific code that delivers a smooth learner experience; cross-platform toolkits are off the table for this phase.

Here’s how I picture the collaboration: you’ll take the wireframes and visual assets I supply, translate them into clean Swift and Kotlin, and keep performance top of mind as we grow the feature set. UI/UX demands are modest for now, so if you’re still honing that craft, that’s perfectly fine—clarity and consistency matter more than flashy animations at this stage. The backend and API layer will be handled separately, so you can stay focused on front-end logic, local data storage, and polishing native interactions.

Workload and schedule are flexible. We can start part-time, move to full-time if it’s a good fit, and you may choose fully remote or drop by the office whenever it suits you. All I ask is regular check-ins, version-controlled commits, and an eye for small but meaningful improvements as we iterate.

Deliverables (milestone-based)
• Fully functional iOS and Android builds running on current OS versions
• Source code in a shared Git repository
• Basic onboarding documentation so other team members can compile and run the project

If you love writing native code and want to help create tools that make learning easier, send over your portfolio or a quick demo app you’re proud of. Looking forward to working together!

Skills: Mobile App Development, iPhone, Android, Objective C, Swift, Blockchain, Kotlin, iOS Development, Android App Development

I’m building AmonixPlay at A5 Labs—a multi-chain Web3 platform that fuses AI-driven insight with provably fair Play-to-Earn mechanics. Our immediate need is for someone whose core strength is blockchain development. Your mission will be to help us push scalability, decentralized identity, and real-time transaction verification to production grade while keeping the player experience seamless.

What the work looks like
• Architect and implement cross-chain smart contracts, side-chain or Layer-2 solutions, and security-first token logic that can stand up to millions of daily micro-transactions.
• Integrate on-chain game-state updates with our existing AI modules so rewards, leaderboards, and NFTs remain tamper-proof yet instantly verifiable.
• Translate complex economic or game-theory models from our research team into code that runs efficiently on chain.

Why your background fits
You indicated blockchain development as your main area of expertise and have experience building custom platforms to drive engagement and retention—exactly what we need as we refine AmonixPlay’s reward loops and player economy. Familiarity with Solidity, Rust, Substrate, or similar toolchains is welcome, but a track record of delivering robust custom solutions matters most.

Engagement details
The role is remote-first with flexible commitment levels; I’m open to full-time, part-time, or contract structures. Tell me what bandwidth you can dedicate and show code samples or repos that prove your chops.

Acceptance criteria
• Modular smart-contract suite deployed on at least two EVM-compatible chains and one non-EVM chain
• Gas-optimized reward distribution logic verified by automated tests (>90% coverage)
• Documentation outlining upgrade paths and security considerations

; Description: Software Engineer, Self-Sovereign Identity & Experience (MVP)
Role: Software Engineer, Self-Sovereign Identity & Experience (Freelance / Part-Time to Full-Time Potential)

Project: Selfverse 1.0 - Identity Patch Installer MVP

Location: Remote (EST])

About Selfverse:
Selfverse is reimagining digital identity and human-computer interaction. We believe reality can function as a personalized operating system, where every individual has a living, evolving digital twin that empowers true digital sovereignty. Our mission is to move beyond the "user" to cultivate "myths" – individuals who control their narrative, data, and digital experience. The "Identity Patch Installer" is our foundational MVP, a unique, poetic onboarding experience designed to help individuals consciously define their digital self.

The Opportunity:
We're seeking a highly skilled and creatively-minded Software Engineer to translate our visionary no-code prototype into a robust, secure, and extensible MVP. This is a unique opportunity to be a foundational technical contributor to a project that aims to redefine digital identity, privacy, and personal agency. You'll work at the intersection of cutting-edge technology (decentralized identity, AI, privacy-preserving tech) and deeply human experience design.

What You'll Help Build (Initial MVP Focus):

Custom Interactive UI: Elevate our no-code Identity Patch Installer prototype (currently in [Typeform/Webflow/Tally]) into a deeply engaging, custom front-end experience. This includes dynamic visual feedback for "emotional state dials," "aesthetic vibe palettes," and "growth edge visualizers."

Secure User System & Data Vault: Implement the foundational architecture for self-sovereign user accounts. This involves:

Decentralized Identifiers (DIDs): Integration with a DID method for user-controlled identity.

Verifiable Credentials (VCs): Structuring and managing the "patches" (emotional state, aesthetic, ethical code, needs, growth edge) as cryptographically signed VCs.

Personal Encrypted Data Vault: Designing and implementing a secure, local-first (or highly encrypted cloud-agnostic) data storage mechanism for sensitive user data, ensuring end-to-end encryption and user control over keys.

Modular & Extensible Architecture: Laying the groundwork for future "modular mood engines," "Self APIs," and other "emotional plugins." This requires foresight into how the system will grow and integrate with external services in a privacy-preserving way.

Early AI Integration (Optional but a Big Plus): Integrate initial, client-side AI capabilities for subtle personalization hints, archetype advice based on user inputs, or simple content filtering rules, while adhering strictly to privacy-by-design principles. This might involve leveraging open-source LLMs or local inference models.

What We're Looking For (Required Skills & Experience):

Strong Front-End Development: Proficient in modern web frameworks (e.g., React, Vue, Svelte) with a keen eye for engaging UI/UX and fluid animations. Experience in translating abstract concepts into intuitive interfaces.

Deep Understanding of Decentralized Identity (SSI):

Solid grasp of Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) (W3C standards).

Familiarity with various DID methods (e.g., did:ethr, did:ion) and their practical implementation.

Understanding of cryptographic primitives (key management, digital signatures) relevant to SSI.

Security & Privacy-by-Design Mindset: Proven experience building secure applications, with a strong emphasis on data privacy, end-to-end encryption, and minimizing data exposure. Knowledge of common security vulnerabilities and mitigation strategies.

Backend / Data Storage Proficiency: Experience with robust, scalable, and ideally, local-first or decentralized database solutions (e.g., IPFS, IndexedDB, Realm, encrypted cloud storage APIs).

API Design & Implementation: Ability to design clear, flexible, and secure APIs (e.g., GraphQL) that allow for future integration with the "Self API" concept.

Version Control: Proficient with Git and collaborative development workflows.

Problem-Solving & Creativity: Ability to tackle complex, abstract problems with innovative and elegant technical solutions. Enthusiasm for exploring uncharted territory in digital identity.

Nice-to-Have Skills & Experience:

AI/ML Integration: Experience with client-side AI (e.g., ONNX Runtime, TensorFlow.js) or integrating with large language models (LLMs) via APIs (e.g., OpenAI, Claude). Understanding of privacy-preserving AI techniques (e.g., federated learning, differential privacy, ZKPs).

Blockchain Fundamentals: Basic understanding of blockchain concepts for anchoring DIDs and VCs, but not necessarily smart contract development (unless the chosen DID method requires it).

Desktop/Mobile App Development: Experience with frameworks like Electron, Tauri, React Native, or Flutter to build cross-platform native experiences.

Open Source Contributions: Familiarity with contributing to or leveraging open-source identity projects.

What We Offer:

Impact: A chance to build the foundational technology for a truly transformative project.

Autonomy: Significant ownership over the technical direction and implementation of the MVP.

Collaboration: Work closely with the visionary founder(s) on a project at the forefront of digital innovation.

Flexible Engagement: Start as a freelance/part-time contractor with the potential to transition to a full-time role as funding and product maturity grow.

Competitive Compensation: Commensurate with experience and the groundbreaking nature of the project.
