Hire the Best DirectShow Developers

I build native iOS and Android applications that work in the real world, in the field, offline, in complex physical environments where most mobile solutions fall apart. My focus is on technically demanding work: augmented reality and spatial computing, LiDAR-based 3D reconstruction and site scanning, RoomPlan-based room and space capture, GIS and GNSS field data collection, BLE and IoT device integration, and AI/ML features that actually ship. Not demos, production systems. I'm the founder of Quality Wolves, a senior-only engineering team. Everyone on the team has owned full project cycles and made architectural decisions. We take ownership of the technical scope, surface what matters, and keep things moving. You stay focused on your product, we handle the build. What I build: Native Mobile: Swift, SwiftUI, Kotlin, full-cycle iOS & Android development, App Store and Google Play delivery AR / Spatial Computing: ARKit, ARCore, RealityKit, RoomPlan, LiDAR scanning, point cloud processing, 3D reconstruction, Apple Vision Pro. GIS & Field Data: GNSS/RTK integration, offline-first architecture, geospatial data pipelines, custom map layers, QGIS compatibility AI & ML: LLM integration, computer vision, NLP, on-device inference with Core ML and TensorFlow Lite, OpenAI and custom model pipelines, TTS/STT Connectivity: BLE pairing flows, LoRa, IoT sensor integration, background sync, beacon tracking Our senior engineers use AI tools deliberately, not as a substitute for judgment, which means faster delivery without trading speed for technical debt. Good fit if you: Need someone who operates independently without hand-holding Are building something with real operational complexity Have been burned by teams that shipped demos and called it done Describe the problem you're trying to solve, send a message, and let's talk specifics.

15+ years shipping production systems: Unity games, XR installations, and AI features that hold up after release. I help teams ship AI inside real products - agents, orchestration, RAG, and Unity/C# inference - with clean architecture, measurable quality, and release discipline. When the experience needs a web or backend layer, I own that too. What I deliver - LLM apps & agents: tool calling, multi-step workflows, planner/executor loops, human-in-the-loop review - Orchestration: Semantic Kernel, graph-style agent flows, custom runtimes, queue/worker pipelines (Temporal / Hangfire / BullMQ) - RAG: chunking, embeddings, hybrid search, reranking, grounded answers over docs, CMS, or game data - C# / .NET AI: Semantic Kernel, Microsoft.Extensions.AI, OpenAI & Azure OpenAI, ONNX Runtime, ML.NET - Unity AI: Unity Sentis / Inference Engine, on-device & server-side inference, AI NPC/dialogue, editor & content copilots - Realtime AI: streaming chat, STT/TTS voice flows, WebRTC + LLM backends for live experiences - Production layer: auth, rate limits, cost controls, tracing/evals, fallback models, safe prompt & tool boundaries Unity, XR & gameplay Unity LTS · C# · URP/HDRP · Addressables · Timeline · Cinemachine · Shader Graph · custom tooling · CI build pipelines OpenXR · XR Interaction Toolkit · AR Foundation · Meta Quest · HoloLens 2 · Apple Vision Pro Netcode for GameObjects · Photon Fusion/PUN · Mirror · PlayFab · WebSockets · WebRTC Around the experience (when needed) React / Next.js · Node.js/TypeScript · PostgreSQL · Redis · Docker · AWS · CI/CD · Sentry / Grafana Selected results - Mixed-reality museum installation in under 10 weeks - thousands of daily visitors, no downtime - Internal Unity toolchain that cut level-design iteration time significantly - Legacy PHP monolith to Kubernetes services with much faster, safer deployments - WebRTC multiplayer backend scaled to high concurrency on AWS spot capacity How I work I use modern AI tooling to move faster, but I still own architecture, performance, tests, and release quality. Small iterations, early measurement, maintainable code your team can keep after handoff. Best fit AI features inside Unity/XR or realtime products, agent/RAG backends for live experiences, or end-to-end ownership from prototype to production under a hard deadline. Share the goal, constraints, and timeline - I'll tell you quickly what's realistic and how I'd approach it.

Most founders I talk to have the same story: months wasted on agencies, budgets burned on developers who disappeared, and still no live product. Recent win: I migrated a live production site handling 250k+ monthly visitors from Lovable to Claude Code + OpenAI Codex in 2 hours. Organic traffic doubled to 500k after the migration. I then set the founders up with Claude Code and Codex so they now ship their own updates, SEO content and automations without a technical background. That is my focus: not just building your MVP, but handing you a system you can run, improve and scale. Results: - Trimi: Lovable to Claude Code migration, 250k to 500k monthly visitors - RemoteOpenClaw: my own AI skills directory, grown to 60,000+ monthly visitors with technical SEO - Milpath: AI SaaS built with Claude Code and Codex, $5k MRR within 90 days - Helpie AI: 1,000+ monthly active users - O-ts: 2x conversion rate after rebuild I'm Zac. One developer, military veteran, based in London. You talk to me, I build it, we ship. No account managers, no handoffs, no surprises. I also teach this exact stack to 3,000+ developers. You're hiring the source. WHAT I BUILD - MVP development and SaaS development: idea to working MVP to live product taking payments - AI app development and AI agent development: Claude API, OpenAI API, RAG, LLM integration, chatbots, OpenClaw agents - Lovable rescue and vibe coding cleanup: Lovable, Base44, Bolt.new, Replit and v0 apps that are 80% there but broken or not production-ready - Migrations: Lovable to Claude Code, Bolt.new to Claude Code, Replit to production, Base44 to production, no-code to production - Supabase architecture: auth, Row Level Security (RLS), edge functions, Postgres schema design - Stripe integration, webhooks and subscription billing - Automation workflows with n8n, Zapier and Make - Landing pages with technical SEO, GA4 and GTM tracking - Claude Code and CLAUDE.md setup so your team builds AI-native Stack: Lovable, Claude Code, OpenAI Codex, Base44, Replit, Bolt.new, v0, Cursor, Supabase, React, Next.js, TypeScript, Vercel, Stripe, n8n, OpenClaw. THE GUARANTEE - Free scoping call before you spend a penny. We map the features, flows and milestones. If we're not a fit, you walk away with a clearer vision anyway. - Working prototype in 3 weeks. Real functionality, live database, not a mockup. - Unlimited revisions within scope, with detailed specs agreed upfront. HOW WE CAN WORK 1. Fixed-price build: MVP, SaaS platform, migration or rescue, scoped upfront with a proposal within 24 hours 2. Fractional developer (10 to 30 hrs/week): ongoing feature development inside your product 3. Post-launch retainer (from $650/month): priority fixes, updates, monitoring and improvements so your product never goes stale Most clients start with a fixed build and keep the retainer. You own the code either way. Zero lock-in. WHY I'M FAST I'm AI-native. Lovable, Claude Code, Codex, Supabase, n8n: this is how I build every day, not occasionally. I ship in weeks what traditional teams do in months, because I know how to architect, prompt, debug, refactor, secure and deploy with these tools properly. Anyone can vibe code. Not everyone can make it production-ready. Quality included as standard: clean architecture, secure auth, Row Level Security, technical SEO, responsive design, performance optimisation. "Wow, what a relief! I was stuck on this website issue for way too long, and Zac came in and knocked it out with ease. Super fast, super professional, and honestly just made the whole process stress-free. Couldn't be happier." I keep my project load small so every client gets my full attention. Every week you spend searching is a week your competitor is building. Hit Invite to Job and tell me what you're working on. I'll send a fixed-price proposal within 24 hours.

I architect and build autonomous AI agent systems -- not chatbot wrappers, but production multi-agent pipelines with real-time orchestration, serving paying customers. Most recently as Co-Founder of Oracia.ai: built a system reaching $10-15K MRR serving 100+ realtors across US and Brazil, processing 1.5M messages in 90 days at sub-200ms. Selected for Web Summit Rio 2026 ALPHA Programme. The architecture: → 9 LangGraph state machines running on a single Cloudflare Worker → Custom parallel branch convergence with graph pause/resume on a stateless runtime → 6-stage message validation pipeline (draft → fact-check → compliance → template selection) → Multi-modal processing at edge: Deepgram STT, Gemini vision/video, OpenAI embeddings → 20+ Cloudflare primitives composed together (5 Durable Objects, 9 KV namespaces, 2 Vectorize indexes, 5 Queues) → Real-time dual-channel delivery via WebSocket + SSE I also fine-tune LLMs — LoRA/QLoRA adapters on Gemini 12B and LLaMA with custom Python training scripts. What I build for clients: • Autonomous AI agents and multi-agent workflows (LangGraph, OpenAI Agents SDK, ReAct loops) • Production LLM pipelines with tool-calling, RAG, and vector search • Edge-first backends on Cloudflare Workers (Durable Objects, Queues, Vectorize, KV, R2) • Full-stack applications with Next.js 15 (React 19), Prisma, Stripe, Clerk • Real-time systems (WebSocket, SSE, WebRTC SFU/MCU architectures) I work US hours from India. Let's build something hard.
