Production Solana copy-trading bot for Solana Hyperion Solana Hyperion is a Windows 10/11 desktop workstation. Version 0.14.0 is already packaged. Python 3.12, PyQt6, local SQLite. It watches public wallets, stores PAPER orders, and draws one-minute candles when a mint has a public pool. PAPER fills are simulated and are never signed or broadcast. LIVE trading is disabled and must stay disabled until a separate, explicit authorization in this contract. Wallet copy is already in the strategy list and is turned off. The current reason is: “Signatures are unclassified, so a copy cannot choose buy or sell.” The missing piece is a decoded swap. This contract makes copy trading production-ready. Do not replace the kernel, the local database, or the fail-closed default. What...

...step in on a ticket-by-ticket basis and close work related to both AWS data engineering and Power BI dashboard development. On the AWS side the tickets you will pick up revolve around building or extending data pipelines and handling the transformation / ETL layers that feed our analytics stack. Expect hands-on work with typical services—think S3, Glue, Lambda, Redshift or Athena—and plenty of Python or SQL scripting to keep things automated and testable. Once the data is landed, many tickets jump straight into Power BI. Your focus there will be on stitching new data sources into existing models and turning those datasets into polished, well-documented reports. Most dashboards already have a wireframe, so speed and best-practice DAX are key. Workflow • Ticke...

...path. Once the databases are safely online in the new cluster we will migrate the remaining application services, port any Python 2 code to Python 3, and bring ageing Go services to their current releases. All changes must be validated against a mirrored environment holding production-sized data, followed by a staged DNS cut-over; the old stack stays live as the fallback until sign-off. Deliverables • Terraform codebase and GitLab/GitHub CI pipelines • Hardened EKS cluster with Gateway API ingress in production • Rebuilt, scanned container images • Upgraded Redis & PostgreSQL instances with rollback scripts • Migrated and upgraded application services (Python 3, modern Go) • Maintenance runbook and recorded handove...

I’m building and iterating on a suite of web applications and want every line of code to move fast without sacrificing quality. You’ll jump straight into a modern stack where Python handles the heavy lifting on the back end and JavaScript drives interactive front-end experiences. Day to day you’ll design new features, refactor legacy pieces, write and debug code, and resolve production issues as they surface. The twist—and where you’ll really shine—is how comfortably you weave AI into that workflow. I already rely on GitHub Copilot for rapid scaffolding and on OpenAI GPT-3 for tasks such as test generation, documentation drafts, and quick proof-of-concept scripts. You should be just as fluent, knowing when these tools speed things up and when t...

This project centers on designing, building, and maintaining production-grade data pipelines that move and transform large volumes of structured data. I’ll rely on your expertise in SQL, Python, and modern ETL orchestration to collect, process, and serve datasets reliably, while enforcing rigorous data quality and governance standards. Infrastructure expectations • Cloud: the core deployment targets are AWS and Google Cloud Platform, so solutions should align with services such as S3, RDS, Lambda, BigQuery Storage API, or similar offerings on those clouds. • Warehouse layer: Snowflake will be the single source of truth; pipelines need to load, model, and optimize data within that environment. • Workflow optimisation: automated monitoring, logging, and alert...

...whenever communication is possible. The core of the job is a runnable simulation that plays out on an interactive map: I want to watch vehicles move, see packets hop between them, and toggle between two forwarding strategies: • an arbitrary, “send-whenever-in-range” method, and • a direction-aware method that chooses relays based on the vehicle’s heading. While the platform is flexible—Matlab, Python, or any other tool you feel is best—what matters is an intuitive, browser-like visualization where I can zoom, pan, and click a node to inspect its current payload. Once both strategies run across identical mobility traces, I need a concise comparison of • data transfer speed, • number of hops, and • message delive...
