I’m Muhammad Tegar Saputra, an independent developer. I build responsive interfaces, simple full-stack workflows, Android/Windows utilities and practical scripts—from one defined task to a reviewable preview, source code and handover notes.
Responsive websites & UI
Business and product pages, mobile layouts and focused interface improvements from your design or reference.
Focused full-stack workflows
Forms, lists, search, editing and exports with simple rules. Storage, accounts and integrations are agreed before development.
Android or Windows utilities
A small utility or defined app feature for one agreed platform and device environment, with a preview build and source.
Scripting & file/API tools
Python or JavaScript for a repeatable input-to-output task: CSV/JSON cleanup, file processing or a permitted API workflow.
These are personal product and prototype projects. Each case separates demonstrated results from untested features. I use AI-assisted development with review and testing; optional AI or visual tools support the agreed outcome.

01 / Original web toolkit
Captured 7 November 2026 using the built-in sample image. Original application; the full product preview is access-restricted.
02 / Browser-demo input
Actual portfolio demo, 7 November 2026. An 800 × 480 sample with size/format controls; this mini-demo processes images only.
03 / Observed image export
Browser check, 7 November 2026: WebP export at 960 × 576, about 10 KB. Output status and download filename are visible. PDF and batch tools were not tested here.
MASCOT SUPPORT / FEATURED WEB WORK
Mascot Support
An embeddable mascot and chat panel, configured here to answer questions about this portfolio.
My contribution
Project owner; AI-assisted development and integration of the SDK, chat panel, reviewed knowledge, Cloudflare API and D1 storage.
Demonstrable result
Public OpenRouter answers were verified through the API and real widget, with source references. FAQ fallback and session reset were also checked.
Scope & limits
This public version provides portfolio Q&A only, with a shared AI budget. It has no operator inbox and does not send WhatsApp or email messages.

01 / FAQ in the initial installation
Local-preview archive, 7 November 2026: the original SDK answers from published FAQ. This image is not evidence of an AI model call.
02 / Panel on the public website
Widget on the public portfolio, 7 November 2026. Separate Cloudflare API/panel, with three suggested questions.
03 / Project answer with sources
Public-widget check, 7 November 2026: a Tegar · AI answer distinguishes RemotePad/SoundBridge and their demo limits, with source references.
XANLY / FEATURED WEB WORK
Xanly Learning Experience
A learning interface that turns study material into flashcards, practice and quizzes within Xanly.
My contribution
Product owner; AI-assisted development of the study flow, interactive cards and practice interface.
Demonstrable result
Actual product screenshots show the flashcard interface; companion Tutor and product-site views provide context for the same product.
Scope & limits
Personal product, not a client engagement. No measured learning improvement, active-user count or business result is claimed. Related Xanly cases are features of one product.

01 / Flashcard interface
Xanly product screenshot using demo material. Shows the card and study controls, not measured learning improvement.
02 / Product context: AI Tutor
A companion feature in the same Xanly product, shown in guest mode. Not a separate client engagement or proof of all AI responses.
03 / Public product website
Public Xanly product site, captured 7 November 2026. Documents the product presentation, not user statistics or private account data.
REMOTEPAD / PROJECT EXPLORATION
RemotePad
An Android controller for Windows, with gamepad, mouse and keyboard modes plus a layout editor.
My contribution
Project owner; AI-assisted development of the Android interface, control profiles and Windows companion workflow.
Demonstrable result
The Android app runs on physical devices. The gallery documents gamepad, mouse, keyboard and layout screens across explicitly dated builds.
Scope & limits
Private preview. The browser demo simulates local input only; it does not control a PC. Latest screenshots do not prove connectivity or compatibility with every game.
A conversational learning interface that connects AI explanations with structured, interactive practice.
My contribution
Product owner; AI-assisted development of the chat interface and rendering of structured quiz controls.
Demonstrable result
The product screenshot shows the Tutor interface and learning entry points in guest mode.
Scope & limits
This is a feature of Xanly, not a separate client project. The portfolio case does not run the original Tutor model or demonstrate every generated answer.
A news module that brings NHK Web Easy JSON feeds and the Hacker News API into one consistent interface.
My contribution
Product owner; AI-assisted integration of feeds, data normalization, source links and duplicate-ID handling.
Demonstrable result
The reviewed implementation normalizes titles, dates, IDs and URLs; the case diagram explains the architecture.
Scope & limits
Feed/API integration, not HTML article scraping. The diagram is an illustration; provider availability and load capacity are not established by this portfolio.
A custom Frappe/ERPNext application for guided input, source review, approval and draft-document workflows.
My contribution
Project owner; AI-assisted customization in the Nexora app, preserving the Frappe/ERPNext foundation.
Demonstrable result
Three original archived screens show a synthetic input/review, a follow-up queue and linked demo-order traceability.
Scope & limits
Screens were captured on 8 September 2026 with demo data. They do not prove a fresh end-to-end draft-creation run or production readiness. There is no public ERP runtime.
Each caption states the source, date and scope. Open an image to inspect the original size.
01 / Guided input and review
Original Nexora app, archived 8 September 2026. UJI / DEMO-002 input; review still needs clarification. This does not demonstrate a successfully created draft.
02 / Follow-up queue
Archived app screen, 8 September 2026. Test job NX-00001 awaits review. Follow-up status does not modify ERPNext transactions.
03 / Synthetic order traceability
Archived 8 September 2026. Brand Contoh Biru and SAL-ORD-2026-00001 are demo fixtures. Shows linked documents, not real business transactions.
