A comprehensive guide on resume preparation, web hosting, DNS setup, and domain acquisition can be broken down into two main areas: Personal Branding & Career (Resume) and Establishing an Online Presence (Domain, Hosting, DNS).1. Resume Preparation for Technical RolesA modern, effective resume, especially for web or mobile developer roles, should be concise, quantifiable, and tailored to the job description.Structure and FormattingFormat: Use the reverse-chronological format, listing your most recent experience first.Length: Aim for one page for up to 10 years of experience.A-T-S Friendly: Keep the layout clean, use standard headings (Work Experience, Skills, Education), and use keywords from the job description to pass Applicant Tracking Systems (ATS).Contact Info: Include your full name, professional email, phone number, LinkedIn profile URL, and a link to your Portfolio/GitHub/Website (your newly set up domain!).Content Best PracticesSectionKey ContentPro TipProfessional SummaryA 2-4 sentence summary tailored to the job. Lead with years of experience and core expertise (e.g., "Results-driven Mobile Developer with 5+ years specializing in React Native and Kotlin...").Quantify your impact. Mention key achievements with numbers, not just duties.Work ExperienceList company, title, dates, and bullet points. Each bullet should be an accomplishment, not a task. Use active verbs (Developed, Optimized, Led, Architected).Use the 'Challenge-Action-Result' format. Example: "Optimized RESTful API queries, reducing server response time by 40%."Technical SkillsCreate separate sub-sections for your expertise: Languages (JavaScript, Python), Frameworks (React, Flutter), Databases (SQL, MongoDB), Tools (Git, Docker), and Cloud (AWS, Azure).Prioritize relevance. List the skills most important to the target job first.Projects/PortfolioEssential for developers. Briefly describe personal, academic, or open-source projects. Include live links to your work.Showcasing a deployed project on your own domain demonstrates a deep understanding of the full development lifecycle (including DNS/Hosting!).EducationDegree, university, and year. Move this section lower as your work experience grows.Skip GPA unless you're a recent graduate with a high score.2. Establishing an Online PresenceA personal website is your digital portfolio, and acquiring a domain, hosting, and setting up DNS are the foundational steps to launch it.Step 1: Domain AcquisitionA Domain Name is your website's human-friendly address (e.g., www.yourname.com).Choose a Name: Keep it short, memorable, and relevant (ideally your professional name).Choose a TLD: The Top-Level Domain (TLD) is the extension (e.g., .com is generally preferred for credibility, but .net, .io, or .dev are common in tech).Acquisition: Purchase the domain from a Domain Name Registrar (e.g., Namecheap, Google Domains, GoDaddy). Registration is typically a yearly rental.Step 2: Web HostingWeb Hosting is the service that stores your website's files and makes them accessible on the internet 24/7. It's the "house" where your website lives.Choose a Provider: Select a reliable web host (e.g., Hostinger, Bluehost, AWS, DigitalOcean).Choose a Plan:Shared Hosting: Most affordable, great for static sites or small portfolios.VPS (Virtual Private Server) / Cloud Hosting: More power, control, and scalability, ideal for complex applications or technical professionals who need root access.Step 3: DNS Setup (The "Phonebook" of the Internet)The Domain Name System (DNS) translates your domain name into the numerical IP address of your web host's server, directing visitors to the right location.Get Host's Nameservers: Your web hosting provider will give you a set of Nameservers (e.g., ns1.hostingsite.com, ns2.hostingsite.com).Update at Registrar: Log into your Domain Registrar account (where you bought the domain). Find the DNS/Nameserver Management settings.Point the Domain: Change the nameservers from the registrar's default to the ones provided by your web host.Propagation (the time it takes for the changes to update globally) can take a few minutes up to 48 hours.Key DNS RecordsRecord TypePurposeExampleA RecordMaps a domain name (or subdomain) to an IPv4 address (the server's IP).yourdomain.com $\to$ 192.0.2.1CNAME RecordMaps an alias name to another canonical domain name.www.yourdomain.com $\to$ yourdomain.comMX RecordSpecifies the mail server responsible for accepting email messages on behalf of a domain name.Directs mail for [email protected] to your mail host.Final Step: DeploymentOnce your DNS is propagated, your domain points to your host. You then use tools like FTP or your host's File Manager/cPanel to upload your website files (HTML, CSS, JavaScript, etc.) to the hosting server's root directory.
