AI Systems Engineer · Edge AI · Voice & Vision · Agentic Systems

I build multimodal AI systems that run in the real world-from edge devices and on-device inference to cloud agents, memory systems and full-stack products.

Currently developing a fire-safety AI system with trained vision models and edge-oriented inference, while leading technical direction for an AI assistant platform at Mako IT Lab.

YOLO11PythonMLXLoRATinyLlamaGGUFllama.cppEdge AIVision AIMultilingual TTS

Train

Build and refine domain-specific vision and language-model datasets.

Evaluate

Test inference behavior and record reproducible quality and performance results.

Optimize

Quantize compact models and prepare artifacts for constrained-device testing.

Integrate

Connect vision, safety logic, reasoning and multilingual guidance into the wider system.

Evidence boundary

Training, export and integration artifacts are verified. Published throughput figures remain engineering targets until backed by reproducible device benchmarks.

Experience

Building Softwares Since 2020

Product engineering depth with increasing focus on AI systems, edge inference, multimodal interfaces and high-ownership product work.

2024 - Present

Senior Software Engineer @ Mako IT Lab

  • Architect cross-platform products across React Native, Flutter, Next.js, AWS and Firebase.
  • Integrate AI features into large-scale products without losing reliability, mobile performance or product clarity.
  • Lead implementation work across data models, realtime flows, API contracts, release pipelines and frontend systems.

2023 - Present

Founder @ Sheriax Solutions

  • Own AI products from problem definition through architecture, interface design, cloud infrastructure and launch.
  • Build systems around memory, RAG, voice, vision, on-device inference and product-grade AI workflows.
  • Make product and engineering tradeoffs directly: latency, cost, privacy, hardware constraints and user experience.

Projects

Systems, Products and Platforms

Grouped by the kind of engineering signal companies can evaluate: AI systems first, then shipped AI products, then full-stack platforms.

AI Systems

pocket_ai · Mako R&D

Problem: Assistive navigation needs real-time obstacle understanding without a network connection.

Architecture: Offline camera-to-detector-to-spatial-reasoning-to-TTS pipeline with desktop and INT8 edge profiles.

Key achievement: Ongoing Mako R&D for safety devices, including YOLO-family model training; FPS figures are documented targets rather than published benchmarks.

YOLO11ONNXPythonComputer VisionEdge AI

models-edge-devices · Mako R&D

Problem: Safety devices need modular AI pipelines that fit constrained compute, memory and power budgets.

Architecture: Split vision, safety validation and event-triggered small-model reasoning with LoRA, MLX, llama.cpp and quantized deployment targets.

Key achievement: Active Mako R&D across YOLO-family model training and constrained-device deployment planning.

SimpleMem

Problem: LLM agents forget useful context or overfill prompts with noisy history.

Architecture: Semantic memory layer with compression, embeddings and retrieval for long-running agents.

Key achievement: Independently implemented the SimpleMem paper in TypeScript and published it as @sheriax/simplemem; benchmark figures belong to the cited paper.

TypeScriptEmbeddingsVector searchAgents

llm-rag

Problem: Documents need searchable, grounded answers instead of generic chatbot responses.

Architecture: PDF ingestion, chunking, MiniLM embeddings, SQLite vector store and OpenRouter/DeepSeek answer generation.

Key achievement: Built a CLI RAG system with separate ingest and query commands.

TypeScriptBunSQLiteMiniLMOpenRouter

Video Composer

Problem: Short-form video production has repetitive transcription, analysis and assembly steps.

Architecture: Whisper transcription, vision analysis and scripted media generation pipeline.

Key achievement: Automated core pieces of a TikTok/Reels/Shorts production workflow.

OpenAIWhisperGPT-4 VisionPython

AI Products

Kizu

Problem: Financial recovery requires spending context, receipt understanding and practical guidance.

Architecture: Flutter app with Firebase, ML Kit OCR, rule-based tracking and OpenAI GPT for receipt scanning, advice, budgets, savings targets and alerts.

Key achievement: Built a production AI finance wellness app for spending tracking and financial recovery.

FlutterFirebaseOpenAI GPTML Kit OCR

Chatiko

Problem: Users want a companion-like AI product that is simple enough for everyday use.

Architecture: Mobile AI companion with OpenAI/Google AI integrations and Firebase-backed user flows.

Key achievement: Built and shipped as a personal Android product, later folded into Sheriax and now discontinued.

FlutterOpenAIGoogle AIFirebase

Talky

Problem: Language-learning communities need safer content and lightweight AI assistance.

Architecture: Mobile learning app with moderation workflows and Firebase product infrastructure.

Key achievement: In-development Sheriax product with Youhana as sole developer.

Cubanin → Echify

Problem: A social-commerce product needed to evolve from its original cross-platform foundation into a richer video-first marketplace.

Architecture: React Native and Next.js in the Cubanin phase, followed by a full Flutter rewrite with Stripe Connect, S3 and Firebase as Echify.

Key achievement: Served as Tech Lead and Lead Mobile Developer, leading the full React Native-to-Flutter rewrite during the Echify rebrand.
