"The most expensive code is the code you have to rewrite." Fractional CTO for SaaS and B2B commerce companies that already run a business. I own the technical decisions (architecture, roadmap, team and where AI fits) so your product can grow without a rewrite. Writing software since 2008 | 405 Upwork jobs | 9,900+ hours | 100% Job Success | Top Rated Plus | $400K+ earned I'm Vivek Sharma, co-founder of Provis Technologies. Most companies I work with don't need more developers. They need someone senior to decide what gets built, how, and in what order, and then make sure it happens. WHAT I TAKE OWNERSHIP OF 1. Technical direction A roadmap tied to business goals: what to build, what to fix, what to leave alone, and when to build versus buy. 2. Architecture that survives growth Platform, data and integration decisions made with the next stage in mind, written down with the trade-offs. When something already exists, I decide what to keep, what to harden and what to rewrite, including products built quickly with AI tools. 3. Team and delivery Engineering standards, code review and release process, whether your team is in-house or a vendor. When you need more hands, Provis engineers work under my direction, with one person accountable. 4. AI and automation strategy Where AI pays off in your product and operations, where it doesn't, and how to add it without breaking your data, permissions or workflows. 5. Independent reviews An honest assessment of your code, architecture, team or vendor before you commit more budget. PROBLEMS I AM USUALLY BROUGHT IN FOR "We have no senior technical person, so decisions get made by default." "We're paying a dev team or vendor and can't tell if the work is good." "The platform works, but it won't survive the next stage of growth." "Everyone says we need AI. We don't know where it actually pays off." "We built it fast with an AI tool. Now we need to know what to keep." TECHNICAL OWNERSHIP I HAVE HELD TheVault: technical lead of this investor-relations SaaS from its MVP to 50K+ users, 5K+ MNCs and banks and listed companies across five stock markets in Africa. TrueWholesale: led the rebuild of a B2B wholesale business from paper orders and sales agents into a platform. Our case study reports 50,000+ app downloads, 5,000+ products managed and a 200% increase in sales. American Community School, Abu Dhabi: fee-free donation system with a direct ADCB bank integration that removed third-party gateway fees. Practice PPE Exams: 950+ hours as technical owner of a live subscription EdTech platform, including n8n automation. Provis Technologies: co-founded in 2018 and have led its technical direction since, delivering SaaS, commerce and AI systems for clients in India, the UK, the UAE, the US, South Africa and Morocco. HOW I WORK Part-time, on a monthly retainer, with a regular sync and every major decision written down so your team can follow it after I've gone. Most engagements start with a short, fixed-scope technical assessment and a written report, so you see how I think before committing. Technologies I work across: AWS, Python, PHP, Node.js, React, multi-tenant SaaS, ERP/CRM and payment integrations, OpenAI and Claude. NEXT STEP Tell me what your product does, where it's straining, and the decision you're facing. I'll reply with how I'd approach it and whether a fractional CTO is what you actually need.
