Email marketing isn't just about sending newsletters - it's about creating meaningful customer experiences that build trust and encourage repeat business. Hi, I'm Fany! I help eCommerce businesses and small businesses plan and organize email marketing that feels intentional, from campaign planning and welcome flows to email copywriting, customer journeys, and content calendars. I enjoy turning ideas into clear, engaging emails that are easy to read and focused on helping customers take the next step. Here's how I can support your business: ✔ Email campaign planning ✔ Welcome & nurture flow planning ✔ Email copywriting ✔ Customer journey mapping ✔ Campaign calendars & content planning ✔ Email layout & design (Canva) ✔ Email marketing administrative support My portfolio includes concept projects inspired by real eCommerce businesses, where I've planned lifecycle email strategies, customer journeys, welcome sequences, promotional campaigns, and conversion-focused email content. These projects have helped me build a practical understanding of how thoughtful email marketing supports customer retention and long-term growth. I'm comfortable working with Mailchimp and MailerLite, and I'm currently expanding my knowledge of Klaviyo and Shopify through structured learning and portfolio projects. My goal is to continue growing as an email marketing professional while helping businesses create organized, customer-focused email experiences. Tools • Mailchimp • MailerLite • Canva • ChatGPT, Perplexity • Google Workspace • Microsoft Office • Asana, Slack, Click Up • Klaviyo • Shopify Why work with me? • Detail-oriented and organized • Strong written communication • Customer-focused mindset • Reliable and proactive • Committed to continuous learning and improvement If you're looking for someone who genuinely enjoys email marketing, communicates well, and is eager to support your business with thoughtful planning and engaging content, I'd love to connect.

I'm an open-source programmer looking to capitalize on his skill set. I specialize in Rust and I'm a regular contributor of bugfixes and features to various open-source projects involving the language. My expertise lies in low-level optimizations, the notable ones I did for the main rust-lang umbrella being: * Polly optimizer to rustc * Alternative aliasing rule (`#repr(transparent)`) to rust-bindgen * Well-received prototypes for fast-math floating-point optimizations I'm comfortable with `unsafe` Rust code and interop with C or C++. I've been coding since 2009 and have used various programming languages besides those two. Can probably pick up C#, Python, Java, Kotlin or Scala within a day or two if the situation calls for it. Recently did a non-trivial personal project involving the WebRTC standard and I would say I'm reasonably confident in my knowledge of: * Its underlying base protocols (DTLS, SRTP, and SCTP) * Congestion control algorithms * Video encoding involving H.264 and its transport
