21 INR / hourI am an experienced C/C++/C# (.NET)/Python/Java/Fortran 90 programmer. I specialize in the development of high performance cryptographic implementations , deep neural networks, desktop application development (both GUI and terminal applications), graphics programming with SDL 2.0 or SFML and OpenGL, network programming using sockets (both BSD sockets and WinSock), multi threading, system security enhancing applications and writing operating system level code for both Windows and Linux operating systems. I am deeply familiar with the Windows API as well as POSIX API, and I have extensive experience working with intricate projects that use the OpenSSL libraries, libAV (core libraries of ffmpeg), libcurl, GMP and many more! I also develop firmware for embedded micro controllers like ESP32 using the Arduino framework and tools like PlatformIO. I have also worked a lot with Raspberry Pi Linux and developed service applications that runs on Raspberry Pi using C or C++. I prefer developing cross-platform code and I also have experience in industry level communication protocols like HTTP(S), Modbus, IEC 104, MQTT and I am willing to deeply understand any other protocol for the dynamic nature of the project. I love writing efficient, elegant and portable code, that works in the most efficient way possible. I am also a fluent speaker and writer of the English language. If I take up a project, be assured that it will be done with the utmost level of perfection that will make your heart content! Please check out the heartfelt reviews from my clients to understand more about me. I hope to work with you and manifest success in your challenging projects. Thankyou very much for checking out my profile! May God Bless You 🙂Hire aravinda333
50 USD / hourI’ve spent over 20 years living at the intersection of networking, security, and open-source systems—designing, breaking, fixing, and hardening infrastructure that runs the real world. I don’t chase certifications; I chase elegant, battle-tested solutions. If your network needs to bend but not break, if your servers need to survive a pentest or a 3 a.m. crisis, or if you want to replace a pricey black box with a fast, open alternative—I’m your remote mercenary. What I bring to your project: Penetration Testing & Security Audits: Network, web app, and Linux-based forensics. I don’t just prod your perimeter; I think like an adversary and leave you with a clear, actionable vulnerability narrative—not just a tool-generated report. When off-the-shelf tools fall short, I write my own—in Python, C, Ruby, or Rust—to get the job done. Service Provider & Enterprise Networking: From BGP to BFD, MPLS to MikroTik, I’ve built and diagnosed networks with every major vendor and plenty of open-source hardware (VyOS, OPNsense, OpenWrt). Automation is second nature: Ansible for orchestration, Python and shell for the glue, and Go or C when I need a custom network daemon that runs lean and fast. Linux & BSD Mastery (with Code in the Bones): I tune kernels, harden stacks, and automate everything. My toolbox spans shell, Perl, Ruby, and Python for system-level scripting; C, Rust, and Go when performance counts or when I'm building custom appliances, forensics tools, or router firmware from scratch. I treat infrastructure as code—and I code without fear. Architecture & Implementation: Bare-metal, VMware, libvirt/KVM, Podman/Docker—I craft architectures that scale and stay security-hardened from day one. I also have a soft spot for building custom routers and firewalls (yes, from scratch, with performance-tuned code, and yes, they outperform most off-the-shelf gear). Open Source Evangelism & Integration: I design and integrate open-source solutions that replace expensive proprietary stacks without adding complexity. I speak fluent C, Python, and shell for patching, extending, and gluing together FOSS tooling that fits your environment like a glove. The slightly nerdy stuff that makes me better: When I’m not untangling a client’s BGP mess or hunting a persistent adversary, I’m probably fine-tuning my homelab (which has its own weather system by now), solving CTF challenges purely for the love of the puzzle, or building a router that’s an art piece as much as a packet-pushing monster. I appreciate a beautifully configured terminal, but I obsess over functionality and performance—form follows fast. I’m currently operating as a digital nomad with bulletproof internet, so I’m available for remote-only, short-to-medium-term projects for the foreseeable future. If you need a senior troubleshooter who can architect, audit, code, and automate with equal fluency—and who speaks fluent geek without taking himself too seriously—let’s talk.Hire jnbrains
