Solving IT problems for🎖️17+ years. On Upwork: 300+ hours, 6K+ earnings. Lower rates until I reach 9 reviews (5-star). Quality work normally paid at ~$30/hr only NOW available at reduced price. Don't wait until that last 9th review. I value customer satisfaction & robust solutions. Why? Because I can have more spare time and enjoy it later. Welcome! You need your problem solved and I can probably help. Probably. I know the struggle. Looking for a solution or a professional to do a task that is not exactly your expertise. Making fast and right decisions, because everybody counts on you. Trying to fit into the budged. Sudden change of plans. The long hours. The new unexpected task. A half-working solution. Back to the drawing board. The deadlines. The fluctuations in revenue. The customers! How do I know? I've experienced it while I was managing the day to day operations of my own escape room business for 8 years. And additionally working in IT for full or half day as a daily job. That is how I know. That is why I will not waste your time. ✅ I will do my best to solve the issue if I can. ✅ I will not promise things I am not 90% certain are possible. ✅ I will consider the solution which is most beneficial for you from technical and financial perspective. ✅ I usually look for the root cause of the problem and try to fix it once and for all. ✅ Often I had found ideas for solving many clients issues just by having a discussion. What is my expertise? ✅ I will never compromise with security for a bit of user convenience. ✅ I will NOT leave a half-finished solution in the middle. Unless you are not paying the work done. ✅ Free and open source software are a major interest. I have more the 17 years IT experience and I have held different positions in the field. Close to the entire spectrum. You can check my employment history (before Upwork) on my profile. Still, GNU/Linux (a.k.a simply "Linux") system administration stays my favorite one. ✅ I have more than 20 years of experience on the GNU/Linux (a.k.a. just "Linux") command line. ✅ I have close to 10 years with cloud. ✅ I have more than 5 years in DevOps. I have experience with different cloud and hosting providers: ✅ Digital Ocean ✅ Hetzner ✅ Google Cloud Platform (GCP) ✅ Amazon Web Services (AWS) ✅ Namecheap ✅ Vultr ✅ Infomaniak ✅ Linode ✅ OpenStack (I was public cloud system administrator) I've implemented CI/CD in several YAML dialects and know other automation tools as well: ✅ Github Actions ✅ Gitlab CI ✅ Jenkins ✅ CircleCI ✅ Bash shell scripts ;) (before CI was a thing) ✅ Ansible (Infrastructure as Code / IaC; server automation) ✅ Cron / systemd timers ✅ Python ✅ Perl I've used distributions like Slackware, CentOS, Gentoo, Trisquel, Ubuntu and Debian. The last (three) are preferred. So, are we doing a project? Send me a message or an invite and let's get started. P.S. Don't forget to check my project catalog as well.

Full-stack developer with 15+ years of experience building modern web and mobile products — SaaS platforms, client applications, and everything in between. My current stack: Next.js, React Native (Expo), NestJS, Laravel, PostgreSQL with Drizzle ORM, Supabase or Neon, and Turborepo monorepos, deployed to Vercel and Google Cloud Run. I also build AI-powered features using pgvector, embeddings, and LLM APIs. What I can bring to your project: - Clean architecture and separation of concerns, from database schema to deployed UI - Full ownership: I can handle the full stack without handing off pieces - Enterprise background: I've worked with Fortune 500 companies in development, infrastructure, and analysis roles before going fully independent - Fast response during CST hours -- usually within 5–10 minutes I focus primarily on greenfield SaaS and modern stack projects. I still take on Laravel and WordPress work when it's the right fit.

Most organisations don't have a strategy problem. They have a systems problem. Decisions get made, priorities get set — and then nothing moves at the speed or quality leadership intended. That's where I come in. I am a Fractional COO. My specialisation is architecting, building, maturing, and handing over the operating system for your mission, organisation, project, or self — across people, process, technology, and AI. I do not just design systems and leave. I stay through maturation and release only when the system runs without me. Come to me when: ◆ You need a Fractional COO to lead operations from the inside while you focus on growth ◆ A market opportunity has just cracked open and you need to galvanise your organisation to move fast enough to capture it ◆ Your systems and processes need a full redesign — people, workflow, technology, all of it ◆ AI and automation are the next step and you need someone who can architect it, not just implement tools ◆ A critical project has stalled, derailed, or needs to be recovered before it costs you more ◆ You are building something meant to last across generations — a family enterprise, an ecosystem, a legacy institution ◆ You need a personal operating system to run yourself at the level your work requires The Standish Group's CHAOS Report found that 66% of technology and transformation projects end in partial or total failure. My clients are in the other 34% — and they stay there. What I bring to each of those situations: 🔷 Operational Operating Systems Fractional COO leadership, organisational design, team architecture, rhythm and accountability systems, performance management — built to run self-sustaining, without you in every meeting. 🔷 Growth Operating Systems Rapid operational readiness when a window opens. Speed-to-market planning, resource mobilisation, and the internal alignment needed to move before the moment closes. 🔷 Transformation Operating Systems End-to-end business process re-engineering, workflow architecture, systems integration, and the change management to make it stick. 🔷 AI & Automation Operating Systems AI strategy, process automation, CRM architecture, and workflow orchestration — systems that don't just execute tasks but learn and improve over time. 🔷 Recovery Operating Systems Diagnosis, stabilisation, and full recovery for projects that have stalled, overrun, or lost stakeholder confidence. 🔷 Legacy & Family Enterprise Operating Systems Architecture for multigenerational family enterprises, ecosystem governance, and perpetuity planning — systems built to hold across generations. 🔷 Personal Operating Systems Productivity, rhythm, and execution systems for executives, entrepreneurs, and leaders — the personal architecture that lets you run yourself at the level your work requires. 🏢 Background that bridges strategy and delivery: Ernst & Young — transformation and advisory CSC — enterprise systems and programme management ThoughtWorks Africa — scaled from inception to 8-figure annual revenue in under two years Built and scaled a digital agency to 7 figures in under two years Advised 100+ organisations across five continents 🌍 I work with founders post-funding, leadership teams in growth or transition, organisations that have just seen a market crack open, and individuals building work meant to last. My clients span five continents — Africa, Europe, North America, Asia, and Oceania.

I graduated as a B.E. in Computer Science from MSRIT, Bengaluru. I have more than 14 years of IT experience, with exposure to various technologies such as Enterprise application Integration and Web Application Design & Development. I have been working as a Python developer for the past 10 years and during this time I have taken on projects involving various domains and technologies. I have developed many Websites, Web Services, ETL and automation scripts on Python. I have always followed the TDD principles to ensure the final product is bug-free. I have also made a few contributions to the Open Source Community.

I'm a full-stack web developers with many years of experience working with different teams and technologies. Through the years, I had to wear many hats - from frontend developer to Linux server sysadmin. I help small design agencies to manage their servers, build their websites and keep everything secure. I focus mainly on WordPress websites and PHP web applications. I'm not afraid of working on the legacy code, I still maintain an old platform written in PHP5. So if you want to free up your development team from legacy burden, I'm the person you want to hire. I've been working remotely for more than 6 years, and I know the power of good communication.
