We are looking for a developer who can build a safe and reliable system that allows automated posting to multiple TikTok Personal Accounts.

Below are the details of our situation and what we need:

After reviewing the requirements, we found that TikTok’s official API is only accessible through a TikTok Business Account. Additionally, the Business Account status is temporary, after one month, TikTok requires submission of company documents to maintain access.

Given that we manage around 100 accounts, submitting company documents for each one is not feasible. This suggests we may need to consider an alternative approach.

We also noticed that several third-party platforms offer automated posting for personal accounts. We would like to understand how these services are able to do this and whether we can implement a similar solution on our end.

Our priority is to use a method that is safe, avoids any spam-like behavior, and does not put the accounts at risk. We are specifically seeking the safest approach without using TikTok’s official API, since it is limited to business accounts.

Please let me know if you can build this and explain the approach you would take.

Our live-service FPS is suffering a surge of hardware-based, DMA-powered cheats and I need deep technical insight to strike back. If you have dissected Counter-Strike, Valorant, Delta Force: Operation or PUBG from the kernel up, you already speak my language. Reverse engineering is the single most important skill here, but low-level programming and a working grasp of PCIe capture devices, FPGAs or similar DMA hardware are essential to connect the dots.

The immediate goal is to map out exactly how today’s DMA loaders bypass traditional anticheat, then translate that knowledge into practical counter-measures that we can deploy without degrading player experience. I’m concentrating on three areas: cheat detection, cheat prevention and a clear understanding of the evolving attack methods. Expect to work directly with crash dumps, memory snapshots and driver traces; tools such as WinDbg, IDA, Ghidra, PCILeech or similar will be in play.

Deliverables
• Technical report detailing every discovered DMA attack vector against our title, including proof-of-concept traces
• Prototype detection routine or driver hook that flags active DMA readers in real time (source code)
• Recommendations for preventive hardening—kernel, userland and hardware—ranked by implementation effort versus impact

I’ll review each milestone against demonstrable reproduction of the cheat technique and measurable detection or mitigation success on our internal test environment. If your experience matches the description above, let’s get started.

If you are a fraudster, do not contact me. This is highly technical work—do not come here to humiliate yourself.

We would like to have a custom firmware for our specific hardware.

I need a custom desktop application compiled to run smoothly on both Windows 10 and Windows 11. The exact workflow, features, and interface requirements will be outlined once we connect in chat, but the end goal is a polished, installer-ready program that feels completely native to modern Windows environments.

Here’s the scope as I see it right now:
• Build the full desktop application (front-end UI and back-end logic).
• Package it in a standard Windows installer so users can install/uninstall without extra steps.
• Provide well-commented source code along with basic build instructions for future maintenance.
• Ensure compatibility testing on both Windows 10 and 11, addressing any OS-specific quirks.

I’m open to your preferred tech stack—whether that’s C#/.NET (WinForms, WPF, or MAUI), C++ with Qt, or another solid framework—so long as the result is lightweight, responsive, and easy to extend. After we discuss the finer details in chat, we can nail down milestones and acceptance criteria.

If you have a portfolio of similar Windows desktop projects, that will help us get started quickly.

I need a faithful digital twin of several small plastic parts that belong to mobile-device mechanisms. No reference files exist, so you’ll be reverse-engineering directly from the physical samples I provide and building the geometry from the ground up.

The goal is a fully constrained, history-based, parametric model—high detail is essential. Every snap-fit, draft angle, rib, clip, fillet and relief must be captured with a dimensional accuracy of ±0.05 mm, ready for downstream DFM iterations.

You’ll receive close-up photos, caliper measurements and, if helpful, a rough scan; however, the final deliverable must be natively editable in SolidWorks or Fusion 360 and exported as STEP. Alongside the 3D file, include a clean 2-D drawing of key dimensions and a short notes page on how you gathered data and verified tolerances.

Deliverables
• Native parametric CAD model
• STEP/IGES neutral export
• 2-D drawing with critical dims
• Brief measurement & deviation report

Acceptance criteria
• Max deviation ≤ 0.05 mm versus source part
• Feature tree remains fully editable, no rebuild errors
• Clear, English-named features and sketches

Before we start, we’ll lock down the part count and set milestones for each piece so you can show measurement screenshots or overlay checks at every stage.
