    I’m a full-time developer working directly in a live Guidewire ClaimCenter environment and I keep running into questions that slow me down. Most of my challenges revolve around writing efficient, optimized Gosu code that still respects ClaimCenter conventions and integrates cleanly with the existing services we already have in place. I have several code-quality and optimization tools running in the pipeline, so guidance will need to mesh with those rather than start from scratch. What I need is an ongoing, hands-on mentorship: quick walkthroughs when a production incident pops up, deeper sessions where we dissect the current implementation, and regular checkpoints to review the efficiency of new logic before it reaches production. You’ll also help me confirm that documents gen...

    From Pakistan, or India Junior Level work and at low budget. I need a dependable junior-level Python coder to jump into my existing workflow and tackle small, clearly defined tasks as they arise. Typical assignments include writing concise modules, cleaning up legacy scripts, and making sure new code slots in neatly with what’s already there. I’ll supply detailed tickets and unit tests; you return clean, well-commented code that passes those tests. Fluency with core Python 3, Git, and virtual environments is essential. Familiarity with libraries such as Pandas, BeautifulSoup, or Selenium will make your life easier, but an eagerness to learn quickly matters more than any single tool. Turnaround is usually one to three days per ticket. For each task, please deliver: • The ...

    I work full-time on a live Guidewire ClaimCenter implementation and regularly handle production incidents—everything from mis-routed documents to integration hiccups. While I can usually patch issues, I want to move beyond quick fixes and truly master the platform. My immediate focus is on Coding best practices in Gosu. I often find myself guessing when it comes to structuring classes, optimizing performance, or leveraging the framework’s more powerful constructs. To sharpen my skills, I need long-term, hands-on mentoring that covers: • Advanced features and techniques in Gosu (refactoring pattern code, metaprogramming, performance tuning, and testability) During our sessions you’ll walk me through real tickets, explain why a particular solution works in ClaimCent...

    I need a developer who has already completed a Malaysian MyInvois / e-Invoice integration to plug that same expertise into our web-based EMR (ASP.NET C#, Microsoft SQL Server). The immediate goal is automated invoice generation: every time a consultation, treatment or ancillary service is saved in the EMR, a compliant e-Invoice must be created in the background and transmitted to the LHDN MyInvois gateway without any manual touch points. You will work directly in our existing codebase, expose or consume the necessary REST endpoints, handle authentication and digital signing, and persist the MyInvois response so finance staff can retrieve the PDF or XML from inside the EMR UI. Please bring along any helper libraries, middleware components or stored-procedure strategies you have already pro...

    We are looking for a senior Android developer to urgently investigate and resolve a bug in our Android application. This is not a role for someone who needs heavy supervision, trial-and-error guidance, or long onboarding. We need a developer who can quickly understand an existing codebase, identify the root cause, produce a reliable fix, and communicate clearly throughout the process. The ideal candidate is experienced, practical, fast, and comfortable using modern AI tools to accelerate debugging, code review, test generation, and implementation, while still applying strong engineering judgment. We are not looking for someone who blindly copies AI-generated code. We want someone who knows how to use AI responsibly to deliver faster and more reliable results.

    This project centers on a brand-new MS SQL Server CLR-based User Defined Function that performs format-preserving encryption (tokenization) of Personal Identifiable Information. The primary goal of this engagement is to validate that the CLR UDF architecture meets the required throughput target. The cryptographic implementation may use an existing FF1/FF3-1 library or a lightweight placeholder — what must be proven is that the SQL Server CLR layer can sustain the expected load at scale. Every line will be written from scratch and staged in our Development environment. Scope • Implement FF1 and FF3-1 per NIST SP 800-38G in C#. An existing open-source library is acceptable provided it is fully managed and compatible with SQL CLR deployment. • Wrap the algorithms in a MS ...

    I have a Python-based script that has been packaged into an .exe and currently pushes data out using an ADPU-style transmission. I now need that same codebase to send and receive using ATR transmission instead. The core of the job is to modify the existing data-transmission format—no protocol swap or major architectural overhaul, just a precise refactor so every outbound and inbound message complies with ATR rules while the surrounding logic remains intact. You will receive: • The full script source that was frozen into the .exe • Sample ADPU request/response pairs and the matching ATR specification I must follow Deliverables I expect: • Updated Python code with clear comments highlighting every line touched • A rebuilt .exe that runs on Windows 1...

    RTU MODBUS PLC Parser

    I’m working with a Phoenix Contact RFC430 PLC that communicates over MODBUS RTU. From the raw frames it returns, I only need two things: the current status information and any embedded error codes. You can approach this as a lightweight CLI tool, a small cross-platform utility, or a well-documented library in Python, C#, or another language you’re comfortable with—as long as it reliably ingests hex-encoded RTU frames and outputs clean, human-readable values. My typical workflow is to capture traffic with a USB-to-RS485 adapter, save it as a hex dump, and feed that file into the parser. The program should automatically identify the relevant registers, decode them, and highlight any error bits or fault codes defined by Phoenix Contact for the RFC430. Deliverables: &b...
