+
+## Key Projects & Achievements (Current Role)
+
+### Cost Optimisation Algorithm (Biggest Achievement)
+- **Problem:** Finding cost-effective medicine switches took months of manual work
+- **Solution:** Built Python algorithm that ingests 6 months of prescribing data, identifies products with same VMP (Virtual Medicinal Product), finds cheapest alternatives, extrapolates annual savings, and prioritises items for system-wide switches
+- **Technical approach:** Uses dm+d (Dictionary of Medicines and Devices) schema to group therapeutically equivalent products by ingredient, route, and form, then calculates cost-per-unit differentials
+- **Results:**
+  - Process reduced from months to 3 days for initial list generation
+  - Identified £2.8M annual savings potential across 14,000 patients (~£200 average per patient)
+  - Achieved 50% reduction in targeted prescribing within two months of deployment
+  - Dashboard focuses on low-risk, cost-effective switches (essentially identical generic medicines under different brands) — high impact, low effort
+
+### QIPP Efficiency Target Delivery

+
+## Career Goals & Transition Strategy
+
+### Current Direction
+Actively exploring transition from NHS to private sector, targeting pharmaceutical, health-tech, and consulting companies. Recognises that private sector organisations are more likely to use external recruiters than NHS roles.
+
+### Target Roles
+- Senior Manager / Associate Director level (considers Director/Head titles premature at 32 without private sector experience)
+- Medical Affairs
+- Market Access
+- Health Economics and Outcomes Research (HEOR)
+- Healthcare IT Consulting / Principal Consultant
+- Real-World Evidence analysis
+- Digital Health Product Management
+- Population Health Strategy
+
+### Positioning
+- "Pharmacist who builds health tech solutions" — NOT "pharmacist trying to transition into tech"
+- Core differentiator: clinical domain expertise + technical capability + strategic leadership at scale
+- NHS language translation needed: "Deputy Head of Population Health and Data Analytics" maps to "Senior Manager, HEOR" or "Principal Consultant, Population Health Strategy" in private sector terms
+- UK professional communication values evidence-based understatement over American-style self-promotion
+
+### Contacts & Network
+- Connection at Prescribing Services (established contact)
+- Guest panelist alongside data professionals from Aviva, UEA bioinformatics, and social impact data roles
+- LPC representative experience (community pharmacy sector network)
+- Cross-ICB relationships (Suffolk/SNEE colleagues)

+
+## Philosophy & Approach
+
+### On Data-Driven Healthcare
+"What is the question you want answered?" — Andy's framing for colleagues. Not "what's going on with this drug?" but specific, targeted questions that allow data to provide actionable insight rather than vague trends.
+
+### On the Clinical-Technical Bridge
+"The skills gap in healthcare isn't just technical people or just clinical people — it's people who can speak both languages. That gap is your opportunity."
+
+### On Population vs Individual Impact
+"As a community pharmacist, we would dispense 6,000 items a month to probably 3,000 patients. I had lovely relationships with patients — I've cried with patients when their significant others died. But the population of our system is 1.1–1.2 million people. Being able to directly target 50,000 people — if you can incentivise GPs to do a single piece of work cost-effectively that prevents even some of them from having a fall and going to A&E with a broken hip — you can't see that direct impact, but I know it's making a difference."
+
+### On Self-Teaching
+"Don't wait for the perfect course. Find something that annoys you, break it down into steps, Google each step. Your first code will be bad. That's fine — mine was awful."
+
+### On Communication
+"I spend more time in PowerPoint than Python — that's not taught but it's critical." Analysis is worthless if no one understands it.
+

+
+## Website Structure Recommendations (From Previous Discussions)
+
+### Current Site
+- andy.charlwood.xyz — single-page design, personal voice, clean domain
+- Includes LinkedIn links, downloadable CV
+- Currently structured more as narrative CV than portfolio
+
+### Recommended Restructure
+1. **Hero section** (20 seconds to hook) — name, role, value proposition
+2. **Featured projects** (the differentiator — should be immediately visible)
+3. **Technical skills** (prove capability)
+4. **Abbreviated career highlights**
+5. **Contact/links**
+
+### Priority Projects for Case Studies
+1. Cost optimisation algorithm (£2.8M savings, 50% reduction in 2 months)
+2. Opioid monitoring dashboard (patient safety, system-wide)
+3. Tirzepatide Monte Carlo modelling (financial risk, executive decision-making)
+4. DOAC switching scenario modeller (interactive tool for executives)
+5. Prescribing incentive scheme (novel design, patient-level tracking)
+

+
+## Organisational Context
+
+### Norfolk & Waveney ICB Structure
+- Part of NHS Norfolk & Waveney Integrated Care Board
+- Medicines optimisation team sits within broader ICS structure
+- Population health pillar looks 2–5 years ahead to understand risks and posture the system
+- BI team exists separately but historically poor collaboration with medicines optimisation
+- Andy has unusual direct access to ICB databases — typically pharmacy roles don't have this
+
+### ICB Merger (April 2026)
+- Norfolk & Waveney merging with Suffolk (from SNEE ICB)
+- New system will include: NHS Ipswich and East Suffolk (06L), NHS West Suffolk (07K), NHS Norfolk and Waveney (26A)
+- North East Essex (06T) joining Essex ICB
+- Significant alignment work ongoing: formularies, incentive schemes, Blueteq, pathways, policies
+
+### Organisational Challenges
+- Model ICB Blueprint indicates medicines optimisation marked for "review for transfer" to providers
+- Data function deprioritised during ICB merger preparations
+- Team morale affected by organisational restructuring
+- Previous head departed end of 2024, creating leadership gap Andy filled as interim
