Floral Illustrations and Pattern Design I am a digital illustrator specializing in bold, lush floral artwork with a strong graphic edge. Working primarily in Krita, I create rich botanical compositions that blend realism with stylized illustration, making them perfect for art prints, textiles, wallpaper, packaging, and surface design. Because of my background in business, marketing, and commercial design, I do not just create visually striking art. I design with real-world application, print specs, and brand strategy in mind to ensure market-ready results. Featured Works "Crimson Bloom": A dramatic, structured red floral centerpiece surrounded by deep foliage and glistening dewdrop accents. Built around bold contrast, tactile texture, and a rich, grounded natural palette. "Midnight Iris": Two striking violet-blue irises emerging from a dense layer of monstera and structured sword leaves. Focuses on cool tones, intricate line work, and high-contrast atmospheric lighting. Signature Style and Approach My botanical work captures the vitality and drama of nature while maintaining a clean, decorative aesthetic that translates seamlessly into both standalone art prints and repeat patterns. Every piece balances organic geometry, intricate leaf structures, and rich lighting dynamics, built from the ground up to drive real commercial value for your brand. Ways We Can Collaborate: Standalone Art Prints and Posters Seamless Pattern Designs (Fabric, Wallpaper, Textiles) Custom Botanical and Floral Illustrations Commercial Work and Packaging Design Interested in working together? Send over a message or project brief. I would love to bring this same vibrant, nature-inspired energy to your next project.

Project: Elevate Designs – Startup Marketing Package I created a complete visual identity and marketing collateral system for Elevate Designs, a home design and restoration company specializing in interior/exterior renovations. The goal was to build a professional, cohesive brand that feels elevated, trustworthy, and inspired by nature — perfectly reflecting their mountain-region roots and commitment to turning houses into homes. Scope of Work: Custom logo mark and wordmark with a bold, timeless “E” monogram Double-sided business cards featuring elegant typography, a signature mountain-and-home illustration, and clean contact layout Double-sided door hangers designed for direct local marketing, one side with aspirational lifestyle photography and colour palette, the other with detailed service information and a strong “Free Quote Today” call-to-action Circular sticker / merch logo lockup for branding versatility Consistent brand application across all pieces, including a refined green earth-tone palette and nature-inspired iconography The design system balances modern minimalism with warm, approachable details that communicate quality craftsmanship. Every piece was created print-ready with proper bleed, resolution, and production considerations for professional results. This startup package helps Elevate Designs stand out both in person and online while giving them flexible assets for social media, vehicles, packaging, and future marketing needs.

Project: Brand Creation, Marketing Leadership & Digital Launch for Elevation Design From concept to market presence, I built Elevation Design into a compelling, premium brand ready to stand out in the competitive world of high-end interior and exterior design. As Head of Marketing and Brand Creator, I led the full strategic and creative effort that established the company from the ground up and positioned it for sustainable growth. I developed the complete brand identity — including the name Elevation Design and signature tagline “Elevating every space” — along with the visual language, color palette, and sophisticated aesthetic that embodies timeless design, sustainability, and excellence. I crafted the foundational marketing strategy and messaging framework, designed and led the development of a clean, elegant, conversion-focused website, and directed all supporting content and promotional assets, including video materials and client storytelling. By overseeing the end-to-end launch across digital platforms, I ensured every touchpoint worked together to build immediate credibility, communicate the brand’s core promise, and attract quality clients seeking exceptional design solutions. The result is a polished, professional brand presence that not only reflects the quality of Elevation Design’s work but actively supports business growth by connecting with the right audience in a meaningful way. I’m proud of the strong foundation we established together. This project demonstrates my ability to create comprehensive brand and marketing systems that launch companies with clarity, confidence, and lasting impact.

IAbstract. Stem cell (SC) transplantation has shown potential as a therapeutic approach for premature ovarian failure (POF). Despite this, no quantitative analysis has been conducted on the efficacy of SC therapy for POF in humans. To address this gap, the present study conducted a meta-analysis to evaluate the effectiveness of the transplantation of SC in improving ovarian function among POF patients. A systematic review in this regard by searching PubMed, ScienceDirect, clinicalTrial.gov (http://clinicalTrial.gov), and Cochrane's library databases was conducted to identify relevant studies, while associated reviews were also considered. The extracted data included parameters such as estradiol (E2), follicle-stimulating hormone (FSH), follicle count (FC), ovarian weight (OW), number of pregnancies, and live birth. As per the combined effect taking the last follow-up time, the level of FSH and AMH for the SC group was lower than these were at the baseline as (SMD: 1.58, 95% CI: 0.76 to 3.92, P-value: 0.185 > 0.05, I2 : 94.03%) and (SMD: 1.34, 95% CI: 0.77 to 1.92, P-value: 0.001 < 0.05, I2 : 0%) respectively. While the means of E2 and OW for the SC group was higher than these were at the baseline as (SMD: 0.47, 95% CI: 0.73 to 0.21, P-value: 0.001 < 0.01, I2 : 38.23%) and (SMD: 1.18, 95% CI: 2.62 to 0.26, P-value: 0.108 > 0.05, I2 : 76.68%) respectively. The overall effect size measured with proportion of pregnancy and live birth at a 5% level of significance expected SC transplantation results were as (combined proportion: 0.09, 95% CI: 0.03 to 0.15, P-value: 0.002 < 0.05, I2 : 46.29%) and (SMD: 0.09, 95% CI: 0.03 to 0.15, P-value: 0.003 < 0.05, I2 : 1.76%) respectively. Based on the fixed-effects model, the estimated average log odds ratio of Follicles count was 1.0234 (95% CI: 0.1252 to 1.9216). Therefore, the average outcome differed significantly from zero (Pvalue: 0.0255 < 0.05) due to SC transplantation. These results suggest that using SCs to restore ovarian function may be viable for treating POF. However, larger and better-quality investigations would need to be conducted in the future due to the heterogeneity of the examined studies.
