Strategy & Architecture
I start by understanding your users, product goals, and technical constraints. This sets the foundation for software that actually performs.
Rechcel Toledo — AI Developer & Software Developer in Davao, Philippines — phcodeSAGE
At phcodesage in Davao, Philippines, I help teams and founders build AI agents, web and Flutter mobile apps, Rust backends and low-level systems, and real-time software that actually performs.
OUR VISION
Whether it's a web or Flutter mobile app, a Rust backend, low-level systems, or real-time software - I create products that work.
Good engineering isn't just about looks. It's about solving real problems, shipping maintainable code, and getting results. Here’s mine.

FAQ
Common Qs
Get quick answers about working with me and my approach to building software. Can’t find what you’re looking for? Reach out below!
Contact meWhat types of AI and software projects do you typically work on?
I build AI agent workflows, LLM integrations, Voice AI companions, full-stack SaaS web products, cross-platform mobile apps with Flutter, high-performance backends and low-level systems in Rust, and real-time communication systems (WebRTC, WebSockets, live chat).
Can I hire you as a freelance AI developer or software developer in the Philippines?
Yes. I’m an AI Developer and Software Developer in the Philippines (based in Davao City) available for contract, freelance, and dedicated partnerships with companies across Metro Manila, Cebu, Davao, and international teams on AI engineering, custom software development, Flutter mobile apps, and Rust/Python backend systems.
Can you build custom AI chatbots, RAG pipelines, or automate business workflows?
Yes. I design and ship custom AI agents, Retrieval-Augmented Generation (RAG) knowledge-base systems, Voice AI companions, Model Context Protocol (MCP) servers, and business workflow automations using OpenAI, Claude, and Python or Rust backends.
Do you build SaaS MVPs and iOS/Android mobile apps with Flutter and Next.js?
Yes. I help founders and startups take SaaS MVPs and mobile products from concept to production using React, Next.js, and TypeScript for the web, Flutter for iOS and Android mobile apps, and Rust or Python (Flask/FastAPI) for the backend.
How long does a typical project take?
Focused prototypes and landing experiences typically ship in 1 to 3 weeks. Full-stack products, AI applications, and real-time systems usually take 4 to 8 weeks with weekly shippable milestones.
What is your development process like?
You work directly with me—no handoffs or layers. We clarify the problem, build a working interactive interface early, wire up tested backend APIs, and verify across desktop and mobile before launch.
Do you provide ongoing support after launch?
Yes. Several platforms in my portfolio—like Exceed Learning Center and Unbreakable You—are long-term partnerships where I handle new features, maintenance, and performance optimization over time.
Can you work with our existing codebase and team?
Absolutely. Whether shipping features inside an existing Python/Flask, FastAPI, Rust, React/Next.js/TypeScript, or Flutter mobile repository, writing low-level systems and AST linters, or building standalone AI and backend services, I integrate cleanly with your workflow.
