I turn flat websites into interactive 3D experiences people remember — and buy from. Three.js · WebGL · GSAP · React/Next.js. Top Rated, 100% Job Success, 5× Awwwards Honorable Mention. Recent wins: - Real-estate 3D leasing site (Belle Oaks): rebuilt a 50M-polygon architectural model down to ~20k polygons — a full 3D district tour that runs smooth even on mobile. Live in production. - Interactive WebGL scroll landing — 5.0★: "Great quality, attention to detail, and communication." - Seasonal ecommerce site where 15% of visitors placed an order. What I build: - Interactive 3D websites & immersive landing pages (Three.js, WebGL, GSAP) - WebGL product configurators & 3D product viewers for ecommerce and real estate - Scroll-driven storytelling and motion (GSAP, shaders/GLSL) - Full pipeline in-house: 3D modeling (Blender) → design (Figma) → creative development (React/Next.js) Why me: I co-founded Fantik Studio® — you talk directly to a decision-maker and get an award-level team (Awwwards, CSSDA, CSSLight, Dribbble Select 2026) without the agency overhead. Typical path: 3D hero section → interactive 3D landing → full 3D website or configurator. Not sure 3D fits your product? Send me your site or idea — within a few hours you'll get 2–3 concrete ways an interactive 3D layer could lift your engagement and conversions. Free, no strings.

Freelance programmer, bachelor of Computer Science, with several decades of programming experience (since 1999), from backend programming (Perl, PHP, nodejs) to front end (HTML/js/ts). Main strengths: - vast area of expertise, from backend to frontend programming using several platforms and their combinations. - fast turnaround (usually same day - if I available - free from current tasks). Flexible in times and terms. - long term support for completed projects (one month free tech support including small design fixes, free bug fixes ) Main skills for now: - Building a browser based web apps on React, Vue js , Angular, mainly visualization oriented projects - 2d,3d, force graphs, tree graphs, complex combined graphs, dashboards...many more) - using mainly D3.js and Three.js. Over 8 years of experience with over 100 completed projects in this area (some are available online, some shown as screenshots) - backend programming (Perl, PHP), with common stacks (Apache and other web servers, Mysql, SQlite, PostgreSQL, MongoDB, NoSQL and some other dbs). - over 15 years of experience (past years) Have some experience working on multi-platform desktop software applications (using Qt library, targeted more for Linux platform). I use AI where this is justified way and helps to speed up development. Also can help fixing various AI generated errors and problems in code.

I build fast, interactive web maps and data‑visualization dashboards for real estate, logistics, utilities, and city‑data products. 400+ completed projects on Upwork. What I deliver: Interactive maps: Mapbox GL / MapLibre / Leaflet / Google Maps / OpenStreetMap—3D, clustering, custom styling, high performance at scale. Data visualization: D3.js, deck.gl, three.js—charts, heatmaps, spatial dashboards that tell a clear story. Geo features: geocoding, routing, isochrones, drawing tools, spatial analysis (Turf.js, OpenRouteService). Full‑stack support when needed: React, JS, PHP/MySQL, API integrations, data scraping/ETL. My process: You share your use case, sample data, and must‑have interactions. I propose scope, architecture, milestones, and timeline (clear definition of done). You get frequent demos and measurable progress Send me a link to your current map (or a reference), sample data/source, and key interactions—I'll reply with a concrete plan and estimate.

Senior full-stack & AI engineer, 10+ yrs. I ship the hard parts most devs can't finish: production AI/LLM features, complex SaaS, real-time data-viz & canvas, and payments — work used by Shell, Chevron, Baker Hughes, ExxonMobil & Parimatch/GR8Tech. What I build: - AI in production — a 4,250-line LangGraph multi-agent service (qualifier/finder/ outreach agents, cost-aware fallbacks, webhook orchestration). Shipped, not a notebook. - Payments — billing & multi-PSP routing for Parimatch Tech / GR8Tech: hosted payment pages, 3DS/OTP challenge flows, real fintech complexity at scale. - Data-viz & canvas — real-time drilling dashboards for Shell/Chevron/Baker Hughes/ ExxonMobil teams; a 2,027-line WebGL drawing engine; shipped tldraw customizations. - Complex SaaS — multi-tenant architecture, design systems; Next.js/Node/Python/Postgres. Stack: React/Next 16, TypeScript, Node/NestJS, Python/Django, Postgres/Supabase, LangGraph/LangChain, Stripe, AWS/Cloudflare, Three.js/Canvas, Highcharts. How I work: I lead with the failure mode — I'll tell you where a build actually breaks before you hire me, then prevent it. Blunt communication, senior judgment, clean code. Happy to start with a small paid trial so you can see the level before you commit.
