SupportFlow AI is a customer support management system built with Python, PySide6, FastAPI and PostgreSQL.
It helps teams manage customer requests, assign priorities and responsibilities, track conversations, and generate AI-assisted response suggestions while keeping a human in control of the final reply.
I built the application structure, interface, backend integration, database workflows, API layer and automated testing.
The conversation-revision idea sounds useful. I would also check that revision on the server when accepting the send, so a message arriving between review and click cannot slip through. Mark the draft stale while keeping the human edits visible. Two useful regression cases: a...
Agri Guard is a full-stack web application that helps farmers identify plant diseases instantly using AI. Users can upload a photo of an affected plant or describe symptoms in text, and the app returns a diagnosis along with a verified treatment plan.
What I built:
A clean, dark-themed landing page with a hero section, trust badges, feature highlights and clear call-to-action buttons (Get Started, Login to Dashboard)
A Node.js and TypeScript backend with REST API routes, utility modules and environment-based configuration
AI integration for image analysis and text-based diagnosis through the OpenRouter API
A disease database with treatment recommendations, plus scripts to extend it with new diseases
Login and dashboard flow for returning users
My focus: a clear, conversion-friendly landing page, readable typography, consistent spacing and a responsive layout that works on both desktop and mobile.
How do you connect the model's diagnosis to the treatment database? Does it have to match a known disease entry before showing a treatment, or can the model generate recommendations outside that list?
Project Overview
Rechitta is a cinematic, feature-film-directed digital web experience engineered for luxury real estate developers in Dubai. It serves as a unified digital briefing engine connecting property developers with over 40,000 registered brokers across 6 international financial hubs at the exact same instant: 04:11 UTC.
The landing experience advances through an interconnected five-act sequence: Dawn, the Executive Boardroom, the Broker Terrace, the Synchronised World Chronometer, and the Dusk Horizon Loop.
The Problem and Industry Context
In rapid-growth luxury property capitals like Dubai, developers launch multi-billion-dollar landmark towers. However, information distribution traditionally relies on outdated and manual workflows:
Network Congestion: Over 40,000 registered brokers operating across more than 1,200 independent agencies.
The Scheduling Bottleneck: A standard 30-person developer sales team requires 3 to 6 months of repetitive boardroom pitches, phone campaigns, and slide presentations just to brief the local brokerage network.
Language Degradation: Cross-border buyers and international brokers speaking Mandarin, Russian, Arabic, Hindi, or French rely on third-party translation relays, causing severe loss of technical nuance, misunderstandings around payment plans, and delayed transaction closings.
From an engineering perspective, most scroll-driven video websites attempt to bind scroll offsets directly to the video currentTime property. This introduces decoder starvation, dropped frames, scroll judder, and severe performance issues on mobile devices. Rechitta required an ultra-luxury, fluid 60fps interactive narrative without compromising performance.
Key Engineering Architecture and Implementation
1. Discrete Beat Engine and Hardware GPU Decoding
To eliminate scroll judder and decoder stalls:
Developed a custom input state machine (director.ts) driven by an Intent Accumulator. User scroll wheel and touch gesture events accumulate until crossing a defined threshold before committing to a camera move.
Added cooldown guards and idle reset timers to prevent momentum overshoots.
Transitions decode short video sequences at native hardware GPU speeds (1.0x to 3.6x) rather than scrub-seeking raw video elements, delivering a locked 60fps playback experience across both desktop and mobile devices.
2. Mathematical 3D Perspective Homography Warp Engine
To render live, functioning web applications inside smartphones and boardroom monitors within moving cinematic footage:
Built a custom 8-degree-of-freedom perspective homography solver using Gaussian elimination.
Tracked normalised video coordinates across corner vertices (Top-Left, Top-Right, Bottom-Right, Bottom-Left) relative to viewport cover crops.
Dynamically calculated CSS matrix3d transformations in real time, allowing interactive application interfaces and iframes to naturally track moving physical camera angles.
3. Luminous 3D Orb Navigator and WebGL Globe
Built a celestial 3D Orb using Three.js and React Three Fibre that guides the visitor through the narrative.
Anchored orb trajectories directly to video clip timestamps rather than scroll percentages, ensuring spatial synchronisation regardless of responsive layout changes.
Implemented an interactive 3D WebGL Earth featuring custom atmospheric GLSL Fresnel glow shaders, day/night texture blending, and dynamic marker coordinates for global financial hubs.
4. Synchronised World Chronometer (04:11 UTC) and In-Memory Video Streamer
Realised the core philosophy of "The Same Moment" by mathematically calculating simultaneous local times across 6 world capitals (London, Paris, Moscow, Riyadh, Mumbai, Shanghai) from a single 04:11 UTC baseline.
Engineered an in-memory RAM Blob pre-warming engine (CityBackdrop.tsx) that precaches high-bitrate drone cinematography loops to ensure instantaneous switching between hubs with native localised typography (supporting both LTR and RTL scripts).
5. Automated Multi-Tier Video Encoding Pipeline
Built an automated multi-tier encoding pipeline using FFmpeg to support broad device compatibility:
AV1 (10-bit) for modern Chromium browsers.
HEVC / Apple VideoToolbox (10-bit) for hardware-accelerated Safari and iOS WebKit rendering.
H.264 (8-bit) as a universal baseline fallback.
Discretised 60fps WebP keyframes for zero-latency mobile first-frame underlays.
6. Mobile Polish and Continuous Infinity Loop
Eliminated video end-of-clip flickering and playback hangs on iOS and Android devices through preloaded dual-video decoders and state cleanups.
Designed an architectural infinity loop where the Act V dusk horizon smoothly cross-dissolves backwards into the Act I dawn sky for an uninterrupted, continuous presentation cycle.
Design System and Visual Standards
Palette: Deep Obsidian (#0A0A09), Surface Obsidian (#141413), Desert Gold (#C5A572), Electric Brand Blue (#3D6FF5), and Warm Off-White (#FAFAF9).

Playing short clips instead of scrubbing currentTime is an interesting choice. How much video do you keep preloaded on mobile, and what happens if someone moves to the next beat before that clip is ready?
