I help businesses make sense of messy operations, scattered data, and inefficient processes. My strength is getting to the root of a business problem, understanding what is happening, analyzing the numbers and workflows behind it, identifying where time, money, or efficiency is being lost, and turning that into a practical solution. I work across business operations, process improvement, financial analysis, reporting, research, and project workflows, using tools such as Excel, Power BI, SQL, and QuickBooks where they add value. What I can help with: * Business & Operations Analysis: investigating operational issues, identifying bottlenecks, analyzing costs, and turning findings into actionable recommendations * Process Improvement: mapping workflows, identifying inefficiencies, structuring processes, and creating practical systems and SOPs * Financial & Cost Analysis: analyzing expenses, pricing, vendor costs, project costs, profitability, and financial data * Reporting & Data Analysis: transforming raw or fragmented information into structured reports, dashboards, and decision-ready insights * Excel & Power BI: advanced spreadsheets, data analysis, reporting, visualization, and dashboards * SQL & Data Preparation: extracting, organizing, and analyzing business data when a database environment is involved * Project & Operations Support: organizing complex projects, coordinating workflows, managing documentation, and keeping moving parts structured * Business Research: researching markets, companies, competitors, vendors, and business questions and turning the information into useful conclusions I am particularly comfortable with projects where the answer isn't obvious at the start. Give me a messy process, a spreadsheet full of numbers, a cost problem, an inefficient workflow, or a business question that needs investigating, and I can work through the information, structure the problem, and help turn it into a clear next step. My approach is analytical, practical, and independent. I don't need every step mapped out for me; I am comfortable researching a problem, learning what I need, and figuring out a workable solution. If you need someone to investigate what is happening, understand why, and improve the way the work gets done, that's where I can help.

Most engagements start with a 10–14 day Stabilisation Sprint (fixed scope). I install clear ownership (roles/RACI), a KPI scorecard, and a weekly operating cadence so your remote team delivers, and it takes this off your plate. After the sprint, I can stay on 1 day/week (or 8–10h/week) to run the cadence (scorecard → priorities → follow-ups), keep reporting clean, and remove bottlenecks. ✅ What you get by Day 14 (live + adopted): • 1 KPI scorecard (owners, definitions, targets) • 1 weekly cadence (agenda + action log + follow-ups) • 1 lightweight roles/RACI map (handoffs + escalation) • 2–3 critical SOPs implemented for daily use Proof: • +9% net profit improvement (Keen Holdings) • Turnover growth €2M → €7M (Al Grosso) • ISO 9001/14001 + EOS-like cadence; saved 15h/week • Finance toolkit used by 10+ SMEs; ~€5K/month untracked spend removed • Additional credibility: Accepted into independent consultant networks (Catalant, BTG). Here’s what I offer: • KPI scorecards + reporting ownership (incl. Sales + Backend KPIs when needed) • Weekly operating cadence (scorecard review, priorities, accountability) • SOPs, process maps, and roles/RACI (handoffs + escalation) • Tooling oversight (Microsoft 365 / Asana / Slack / Google Sheets) - I define specs and QA delivery with your implementers Selected work: 1. Keen Holdings (UK) — Fractional COO +9% net profit improvement through process work and execution discipline. 2. Al Grosso — COO/CFO Helped grow annual turnover from €2M to €7M over two years. 3. ISO + SOP systems Set up ISO 9001/14001, SOPs, KPIs, and an EOS-like weekly cadence; saved 15 hours/week. Who I work with: • Founder-led teams that need clear ownership and predictable execution • Ops-heavy businesses where delivery or follow-through is messy • Teams that want simple cadence, real KPIs, and less micromanagement • Importers, distributors, and FMCG/product businesses that need sourcing-to-shelf control Secondary track (when relevant): For importers, distributors, and FMCG/product businesses, I can also set up the sourcing → QC → landed cost → logistics → inventory → retail-readiness process, so launches and replenishment stay predictable. When needed, I also support supplier screening, negotiation prep, and margin-risk controls. Message me on Upwork, and we’ll set a short call to confirm scope and the best first sprint.
