What I'm looking for

I’m looking for a Software Engineer or Full-Stack Developer role where I can build modern web applications, APIs, cloud systems, and AI-powered features using React, TypeScript, Python, FastAPI, Node.js, PostgreSQL, Docker, AWS, and LLM technologies.

At Amihan Global Strategies (AGSX), I work across AI platform engineering and security, building RAG and model-training workflows with PyTorch and Hugging Face across 20+ experiments. LoRA/QLoRA reduced GPU memory requirements by approximately 55%.

I also work on secure-agent controls, including prompt-injection testing, retrieval validation, isolated tool permissions, and MCP-aware security controls.

At Ingenuity Software, I built REST APIs and services across six production applications. Indexing, caching, and asynchronous processing reduced average API response time by 32%.

At Syntactics, Inc., I progressed from working under senior-engineer guidance on features and integrations to independently delivering full-stack features. My contributions spanned 30+ business workflows and 50+ production features and releases.
