C Programming Jobs

I need a Python‐based trading bot that plugs directly into Broker's SDK and executes fully automated trades on the NSE. The core objective is a clean, well-documented workflow that: • Authenticates with Broker A’s API and maintains a stable session • Streams live NSE market data from the SDK • Generates, places, modifies, and cancels orders automatically based on my strategy hooks • Logs every request/response for audit and debugging Please build the solution in modular, well-commented Python 3.x so I can swap in new strategies later without touching the integration layer. A concise README with setup steps, environment variables, and example strategy templates will be the final acceptance test.

We are a hotel using a specific electronic door lock. We need to integrate these locks with our Property Management System (PMS) to automate keycard management. The lock company cannot provide an API or documentation, so we need to determine the communication protocol and build a custom interface. Scope of Work: Analyze the communication protocol between the lock system and its hardware. Develop a software middleware/API to connect our PMS to the lock system. The interface must handle core functions: creating new keycards for check-in, extending access, and revoking access at check-out. Provide clear documentation on the protocol and the solution. Test the integration to ensure it is reliable. Dumps of Master Card, Guest Cards, Configuration Cards and Add Locks Card will be provided. Th...

I want to build a Windows-only application that watches the live screen, detects people—including stylised in-game characters—in real time, and immediately drives a game controller so the crosshair locks onto and tracks that target as it moves. The workflow I picture is straightforward: the program captures frames, an AI model spots the person, and a virtual stick signal (XInput, vJoy or a comparable driver) nudges the aim every frame so it stays centred. Smoothness and speed are critical. On a 1080p feed I’m aiming for roughly 60 fps with no more than 40–50 ms end-to-end latency, so techniques such as YOLOv8, TensorRT or a lightweight custom network combined with OpenCV screen capture should fit. You’re free to choose Python, C++, or another language as long...

I have individual, validated firmware blocks for the STM32L432KBU6 that handle an LIS3DH accelerometer (interrupt-driven), an EM4095 RFID front-end, the MCU’s internal touch-sensing controller, and a UART-based E220-400T22S LoRa module. My next step is to merge these routines into one cohesive, ultra-low-power application on our custom PCB. Power optimisation is the top priority. I want the system to remain in STOP mode most of the time, waking through the LIS3DH interrupt and periodic RTC events. When active, each peripheral must communicate reliably without compromising the sleep budget. Key points • Integrate existing C-based drivers into a single project • Configure and test the STOP-mode strategy, ensuring wake-ups from both the LIS3DH and the RTC function every t...

I am building an intrusion-detection system that relies on entropy-based calculations applied over time windows to flag anomalous behaviour in user activity data. The goal is to detect subtle, previously unseen patterns rather than match against known signatures, so the core of the work is an efficient entropy engine that continuously ingests, time-stamps, and scores each event stream for deviation. My data source will be raw user-activity logs—login records, file interactions, command histories, and similar feeds collected from endpoints and servers. You may assume the logs arrive in near-real time (JSON or CSV) and contain at least a timestamp, user identifier, and event type. The system should: • Parse and normalise each record, maintaining a rolling history per user and fo...

I’m building a proof-of-concept access controller that uses Fujitsu’s PalmSecure sensor on a Raspberry Pi. I already have the broad concept sketched out; what I need is a partner who can take it from idea to a working, desk-tested prototype. Hardware setup, software development, and full PalmSecure integration are all in scope. That means choosing the right Pi model, wiring the PalmSecure unit and any relays/LED indicators, and making sure the power budget is solid. On the software side I’m leaning toward Python or C++ on Raspberry Pi OS, but I’m open as long as the PalmSecure SDK runs reliably on ARM. The application must handle: • User authentication via palm-vein templates • Secure data storage and quick retrieval of templates and event logs &bull...

I’m building a Python-based algorithmic trading system and want a clean, extensible codebase that digests both real-time and historical market data out of the box. The goal at this stage is to lay down the “engine room”: data ingestion, strategy hooks, execution routing and basic risk controls, all written in idiomatic Python with clear documentation so additional strategies and brokers can be plugged in later without refactoring. While the specific asset classes and strategy styles can stay flexible for now, the architecture needs to accommodate multiple instruments and timeframes, letting me toggle between back-testing on stored data and live or paper trading on streaming feeds with a single config change. Deliverables: • A modular Python project (virtual-env r...

I need a fin-tech professional to craft a complete day-trading strategy for Indian equities and index derivatives traded on the NSE. Because speed of execution and market nuance matter, I’m only considering developers based in India and will give preference to someone in Gujarat who already understands local brokerage APIs and exchange conventions. Here’s what I’m after: a clearly defined, rule-based intraday system that covers stock and index selection, precise entry/exit logic, position sizing, and risk controls appropriate for Indian market volatility. I want the logic documented and coded so it can be back-tested and, if profitable, deployed live without rewrites. If you normally work in Python, Pinescript, AmiBroker AFL, or another language suited to NSE data feeds ...

The project centers on building next-generation feature sets for our 5G Open RAN Radio Unit (O-RU). All work happens on a Linux-based SoC, so day to day you will live in C and C++, occasionally dropping to Assembly for critical paths and scripting in Python to automate validation. Scope of work You will own the full software path for new O-RU capabilities—from architecture discussions through low-level driver changes, real-time scheduler tweaks, and user-space services—then push the code into our CI pipeline and remote test lab. Although the codebase is mature, the emphasis is firmly on adding fresh functionality rather than just tuning what already exists. Environment & tools • Linux (Yocto build system) on ARM-based SoCs • GCC / Clang, GDB, Trace32, git,...

I am looking to develop a decision-support algorithm that identifies and ranks the best production options across locations, varieties and time windows, based on a large set of variables. The model should evaluate each option using economic factors (costs, prices, margins), agronomic performance (yield, quality, timing reliability), logistics (distance to market, transit time, reliability), and risk (climate, water, regulatory, operational). The algorithm must first eliminate non-viable options using hard constraints (e.g. feasibility, minimum thresholds), and then score and rank the remaining options using a weighted, configurable logic that produces a single comparable score per option. The goal is not pure prediction, but a transparent and scalable optimization engine that supports bett...

I want to commission a purpose-built high-frequency trading engine focused exclusively on stocks and driven by a momentum strategy. The system must ingest real-time streaming market data, react in microseconds, and execute orders with minimal slippage. Key expectations • End-to-end architecture: ultra-low-latency market data capture, signal generation based on momentum indicators, smart order routing, and risk controls. • Exchange connectivity: direct API or FIX gateways to major equity venues; the code has to be exchange-agnostic enough to let me plug in additional venues later. • Deterministic performance: consistent round-trip times under heavy load, with benchmarks and profiling evidence. • Safety nets: position limits, kill-switch, and detailed logging tha...

My spare MacBook has suddenly stopped seeing any wireless networks, even though the other computer on the same desk is happily online. I’m on macOS and, so far, the affected machine can’t detect a single network—home, hotspot, or neighbour—so it’s not just my router. What I need from you is a real-time remote session (Zoom, TeamViewer, or your preferred secure tool) to: • diagnose why the Wi-Fi interface is blind • walk me through any Terminal commands, SMC/PRAM resets, or network-interface reinstalls required • verify that the Mac can once again scan, join, and hold a stable connection I’ll stay on the working computer throughout our session for screen sharing and chat, and I can reboot the faulty Mac as many times as needed. ...

I already have valid login credentials to my coaching app, but the platform doesn’t give a built-in option to save lessons offline. I need every video class I’m enrolled in pulled down from both the Android app and the web version, then handed back to me neatly organised (Course → Module → Lesson, MP4 or the source format). Use whatever reliable method you prefer—Python scripts, yt-dl, network-capture tools, or similar—to grab the streams, keep the original resolution, and avoid quality loss. A light DRM layer may be present, so prior experience with HLS/DASH stream extraction will help.
