I am a Senior Full-Stack Engineer with 8+ years of experience designing, building, and scaling web applications, SaaS platforms, APIs, and cloud-based systems. I specialize in turning business requirements into reliable, maintainable, and scalable software solutions. Over the years, I have worked across the entire product lifecycle—from architecture and database design to frontend development, backend services, cloud infrastructure, CI/CD automation, and production deployment. One of my key strengths is understanding both the technical and business sides of software development. I don't just write code; I help clients make sound architectural decisions that reduce technical debt, improve scalability, and accelerate product delivery. What I Can Help You Build ✅ SaaS Platforms ✅ Customer Portals & Admin Dashboards ✅ REST APIs & Backend Services ✅ AI & Third-Party API Integrations ✅ Subscription & Billing Systems ✅ Payment Gateway Integrations (Stripe, bitcoin BTCPay Server) ✅ Cloud-Native Applications ✅ Internal Business Systems ✅ Real-Time Applications ✅ Secure Authentication Methods (JWT, 2FA / TOTP, WebAuthn / Passkeys) ✅ Network Security & Programming Solutions ✅ Computer Graphics Programming ✅ HTTP/3, QUIC Protocol ✅ Decentralized Application (dApp) Development ✅ EdTech Application Development

I help crypto companies and education platforms turn complex blockchain concepts into clear, engaging content that anyone can understand. With 4 years of experience researching and writing about Bitcoin, DeFi, Layer 1s, Layer 2s, stablecoins, tokenization, AI, and the broader Web3 ecosystem, I create accurate, well-structured articles that make technical topics accessible without sacrificing depth. My approach is research-driven and reader-focused. I verify information, organize it into a logical flow, and write in a clear, conversational style that helps readers build confidence in the subject. Whether it's a beginner's guide, a protocol breakdown, or an in-depth explanation of how a blockchain technology works, I deliver content that is informative, engaging, and easy to follow.

I have taken part in all kinds of translation and proofreading projects. I have a lot of experience translating automobile documents, websites, marketing content (ads), and general texts. I'm also very used to translating inter-company contracts; if companies require me to use a specific word for something vital in the document, then I'll do so. I usually provide translations in MS Word and Excel files, but I can deliver the translations in other code and text files too. Strong in problem-solving and communication. Do not hesitate to contact me if you have a translation project or files needed translating. I’m looking forward to working with you, Priit

Senior full stack developer building ecommerce platforms on Medusa.js, Magneto and Shopify and WooCommerce, headless CMS builds with React, Next.js, Node.js and Python. I'm Abdullah. Most of my work starts the same way: a store or platform that was built fast, grew faster, and is now held together with duct tape. Checkout fails on certain cards. Inventory is wrong in two systems. The CRM has 40,000 contacts and nobody trusts a single field. The original developer is gone. I take over codebases like that, stabilize them, and then build what the business actually needed in the first place. 𝗪𝗵𝗮𝘁 𝗜 𝗗𝗼 𝗠𝗲𝗱𝘂𝘀𝗮.𝗷𝘀 & 𝗛𝗲𝗮𝗱𝗹𝗲𝘀𝘀 𝗖𝗼𝗺𝗺𝗲𝗿𝗰𝗲 Medusa is my main commerce stack and it's still rare to find someone who has run it in production. I build multi-vendor marketplaces, B2B catalogs with customer-specific pricing, and subscription stores — custom fulfillment logic, regional tax handling, and admin panels your ops team can actually use. One marketplace I rebuilt went from [X] to [Y] orders/day without adding servers. If you're stuck between "Shopify is too rigid" and "custom is too expensive," Medusa is usually the answer, and I can tell you in one call whether it fits your case. 𝗦𝗵𝗼𝗽𝗶𝗳𝘆 & 𝗪𝗼𝗼𝗖𝗼𝗺𝗺𝗲𝗿𝗰𝗲 𝗧𝗵𝗮𝘁 𝗢𝘂𝘁𝗴𝗿𝗲𝘄 𝗜𝘁𝘀𝗲𝗹𝗳 Custom apps, checkout extensions, ERP and 3PL sync, migration off creaking themes. The common project: a store doing real volume where every new feature was a different freelancer's plugin, and now nothing talks to anything. I map the mess, kill what's dead, and rebuild the connections so a price change in one place is a price change everywhere. 𝗛𝗲𝗮𝗱𝗹𝗲𝘀𝘀 𝗖𝗠𝗦 & 𝗖𝗼𝗻𝘁𝗲𝗻𝘁 𝗣𝗹𝗮𝘁𝗳𝗼𝗿𝗺𝘀 Sanity, Strapi, Payload, Contentful — wired to Next.js frontends that score green on Core Web Vitals. Marketing teams get an editor they can use without filing a ticket; you get a site that doesn't need a developer to change a headline. 𝗣𝗮𝘆𝗺𝗲𝗻𝘁𝘀 𝗧𝗵𝗮𝘁 𝗗𝗼𝗻'𝘁 𝗟𝗼𝘀𝗲 𝗠𝗼𝗻𝗲𝘆 Stripe is easy until it isn't. I handle the hard parts: ACH and wire routing, split payouts for marketplaces, idempotent webhook handling (no double-charges, no phantom orders), failed-payment recovery flows, and reconciliation your accountant will sign off on. I've untangled enough broken payment code to know the bugs before they happen. 𝗥𝗲𝘀𝗰𝘂𝗲 & 𝗥𝗲𝗳𝗮𝗰𝘁𝗼𝗿 A growing share of my inbox is AI-generated codebases: apps built in a weekend with Cursor or Copilot that demo perfectly and fall over at the first real user. Hallucinated dependencies, no error handling, secrets in the repo. I audit, untangle, and put proper structure under it — without the rewrite-from-scratch invoice. You get a written audit first, so you know what you're paying for before I touch anything. 𝗛𝗼𝘄 𝗜 𝗪𝗼𝗿𝗸 First call: you describe the problem, I tell you what I'd do and what it costs. No discovery-phase invoice to find out what the project is. Weekly demos on a staging link you can click yourself. No "trust me, it's 80% done." You own everything — repo, infra, docs. When we're done you can hand it to an in-house team or keep me on retainer. No lock-in either way. 5,385 hours on this platform and a 100% JSS means I don't take projects I can't finish. 𝗚𝗼𝗼𝗱 𝗙𝗶𝘁 / 𝗕𝗮𝗱 𝗙𝗶𝘁 Good fit: you have a store, platform, or CRM with real users and real revenue, and it needs to work properly. Bad fit: you need a $200 theme installed, or you're shopping for the lowest hourly rate. I'm not it, and that's fine. If your platform is the thing standing between you and growth, send me a message with two sentences about what's broken or what you're building. I reply within a few hours, usually with a question you haven't been asked yet.
