A behind-the-scenes look at how I approach complex design challenges — the strategy, the process, and the results.
How a complete design overhaul transformed NexaFlow's struggling SaaS platform into a conversion machine, tripling their trial signups in 90 days.
NexaFlow had built powerful software but was losing potential customers within seconds of landing on their website. The existing UI was cluttered, the messaging was unclear, and the user journey had no coherent flow. Their bounce rate was above 78%, and trial signups were at a dismal 2%.
I restructured the entire information architecture around the buyer's journey. New hero copy focused on outcomes rather than features. I introduced social proof above the fold, reduced cognitive load by 60%, and designed a clear, frictionless 3-step onboarding flow with a single, dominant CTA.
Weeks 1–2: Heuristic audit, competitor analysis, and 12 user interviews. Weeks 3–4: Wireframing and user testing with Figma prototypes. Weeks 5–7: Visual design system, dark UI with blue accent language. Week 8: Dev handoff with annotated specs and Lottie animations.
Conversion rate lifted from 2.1% to 9.3% — a 343% increase. Trial signups rose 67% month-over-month. Bounce rate dropped from 78% to 34%. The client reported a 4.2× ROI within the first quarter following launch.
How a cohesive visual identity helped a fintech startup raise $4.2M in seed funding and close enterprise partnerships within 6 months of launching.
Vertex Capital was a promising fintech startup with strong technology but a DIY brand that failed to inspire confidence in institutional investors and enterprise clients. Their logo was generic, their color system inconsistent across touchpoints, and there were no brand guidelines for the growing team.
I developed a premium brand identity anchored in trust, precision, and forward-thinking finance. The logo mark — a geometric square within a circle — communicates stability and modern innovation. I established a strict dark-primary palette with electric blue accents to distinguish them in a crowded category.
Brand discovery workshop → competitor visual audit → 3 distinct concept directions → 2 rounds of refinement → full brand guidelines (72 pages) → application across pitch deck, business cards, website headers, social media templates, and email signatures.
Vertex closed their $4.2M seed round 3 months after the rebrand launched. Investor feedback consistently cited the brand as "credible and distinctive." Two Fortune 500 enterprise pilot programs were signed within 6 months, with the brand playing a key role in first-impression meetings.
A user-centered redesign that reduced task completion time by 55% and achieved a 4.8-star rating on launch, becoming a top personal finance app in its category.
The Lumos app had all the right features — budgeting, expense tracking, bill reminders — but users weren't engaging beyond the first week. Exit surveys revealed confusion with the navigation and that users couldn't find core features without multiple taps. The 14-day retention rate was under 20%.
I overhauled the IA placing budgets, spending summaries, and quick-add on the main tab. I designed a "Financial Health Score" as an engaging home screen anchor. Dark-mode-first visual design reduced eye strain for evening use — the app's peak usage window. Micro-animations rewarded spending discipline.
Session recordings review → 20 moderated usability tests → affinity mapping → revised task flows → high-fidelity Figma prototypes → 2 rounds of A/B testing on navigation patterns → design system documentation → implementation QA with engineering team over 3 sprints.
Task completion time dropped by 55%. Day-30 retention improved from 18% to 47%. The app launched to a 4.8-star rating across 2,400 reviews. Featured by the App Store in "Finance Apps We Love." Downloads exceeded 85,000 in the first 60 days post-launch, beating projections by 2.3×.
"Charlotte's case study process was thorough, strategic, and incredibly well-documented. She understood our business goals as well as any consultant we've hired."
"The rebrand Charlotte delivered didn't just look beautiful — it performed. Our investor meetings are completely different now. Everyone notices the brand instantly."
"Charlotte delivered a complete brand system in 3 weeks that our previous agency couldn't produce in 6 months. The attention to detail is extraordinary."
