01 · Services
From Figma UI/UX designs, high-speed Next.js/React frontend development, secure backend APIs, to cloud deployment on AWS/VPS. Every solution is custom-tailored to solve your specific business challenges.
Design corporate websites, service introductions, and conversion-oriented landing pages. Focusing on unique Figma UI/UX designs, seamless mobile responsiveness, and technical SEO readiness.
Transform Figma designs into high-speed Next.js/React code. Fast-responding interface, smooth animations, optimized image/code size, and clean, modular component structures for easy maintenance.
Build business logic, design databases, and write secure RESTful APIs. Ensure accurate data processing, optimized SQL queries, and clean code organization.
Build internal admin panels, CRM management systems, product management tools (CRUD), and interactive data reports using visual charts.
Deploy systems to live production environments. Set up VPS servers, configure Cloud services (AWS), configure domains, DNS, secure SSL (HTTPS), and establish automated deploy pipelines (CI/CD).
Bug fixing and system upgrades. Optimize Google Core Web Vitals speed scores (LCP, FID, CLS), configure Technical SEO, and provide recurring technical support.
02 · How we work
A successful system is the intersection of great UI/UX, robust business logic, and reliable cloud infrastructure. We don't just write code, we partner with you to build sustainable technology solutions.
We dive deep into your operational goals and target audience before writing a single line of code. The product must solve real business problems.
We handle everything from UI/UX design, frontend coding, and backend APIs to database setups. No need to spend time coordinating disconnected developers.
A completed product shouldn't just run well on localhost. DNS, hosting, SSL certificates, Cloud configs (AWS, VPS), and auto-backups are properly configured from day one.
Write tidy, modular code adhering to clean codebase standards. The project is easy to hand over or upgrade in the future without tearing it down.
Every milestone has a specific timeline and acceptance checklist. You approve the Figma designs before placing a deposit and track actual code progress via continuous live previews.
03 · Process
You review the interactive Figma UI/UX designs or backend system/API specifications before placing a deposit. Development only kicks off when you are fully satisfied with the roadmap.
You approve Figma designs or system architecture before placing a deposit. Clear workflow, zero risk for both parties.
Listen to your requirements, analyze business needs, and propose suitable technical solutions along with a detailed quote.
Create actual Figma interface designs based on agreed content. You can preview the visual design style before making decisions.
Once you finalize the interface designs, we will sign a contract and receive a 40% advance to start the coding phase.
Transform static designs into a live product. Build smooth responsive frontend layouts, process backend logic, optimize load speed, and configure basic SEO.
Both parties review the live product based on the initial feature checklist. Once everything is verified to work perfectly, you process the remaining 60% balance.
Deploy the product to your official production server. Hand over all source code, admin accounts, and detailed operation instructions.
Infrastructure & operations
The interface is the visible part. Behind it sits infrastructure built to run 24/7.
04 · Real projects
Some of the case studies below are our real team projects, deployed live for you to inspect interface quality and user experience directly.
lasttrain.seawintech.vnA landing page for a night walking service: a paper-light ground, so the twelve night-street photographs are the only dark, saturated things on the page. The motion is built to award-site standard — a counting preloader, inertial smooth scroll, lines rising out of their masks, a photograph opening inside the headline itself, a drawn cursor, and each route floating its own photograph under the pointer on hover.
eleven.seawintech.vnA perfumery landing page staged like a Dutch still life — materials emerging from a near-black ground under one warm light, bilingual EN–VI. The bottle at its centre is ray-marched in a fragment shader, turning with the reader; eleven numerals kindle down the margin as the page is read.
khoi.seawintech.vn
treeline.seawintech.vnA landing page for a hillside retreat built around a compass axis: a rail on the left reports the bearing and elevation of each space, while window mullions open up as you read. Every movement runs on pure CSS scroll-driven animation — no motion library at all.
pulse.seawintech.vnA one-night event page for a festival of light art and experimental sound staged in a decommissioned water works. The countdown, the night timeline and the artist index all run on plain CSS motion — no animation library, and the entire dependency list is next, react, react-dom.
tide.seawintech.vnThe first issue of an independent architecture publication, laid out like print: a column grid, large serif display type and full-bleed plates. Plate reveals and counter-drift run as CSS scroll-driven animations where the browser supports them, falling back to an IntersectionObserver where it does not.

05 · SEO & Speed
Speed optimization and codebase structuring are implemented directly at the root (Core Web Vitals). Minimizing heavy libraries, every single line of code is written to be search-crawler and human-friendly.
Measured with Google Lighthouse on the production build before handover — the speed report ships with the acceptance record.
Using standard semantic HTML5 tags (header, main, section, article, footer) helps Google's bot read and index your core content accurately.
Full configuration of titles, descriptions, and social preview cards, ensuring professional layouts when sharing links on Zalo, Facebook, or iMessage.
Smart keyword distribution. Only a single H1 tag for the page's core topic, sub-sections organized via H2/H3 for long-term SEO.
Automatically converting images to ultra-light WebP/AVIF format with responsive sizes, deferring offscreen images to save bandwidth.
Focusing on LCP (Largest Contentful Paint), FID (First Input Delay), and CLS (Cumulative Layout Shift) for green speed scores.
Automatically generating sitemaps and crawler directive files to guide search engine bots to locate your valuable pages quickly.
