𝗧𝗵𝗲 𝗦𝘂𝗽𝗽𝗼𝗿𝘁 𝗔𝗴𝗲𝗻𝘁 𝗪𝗵𝗼 𝗧𝘆𝗽𝗲𝗱 𝘁𝗵𝗲 𝗦𝗮𝗺𝗲 𝗔𝗻𝘀𝘄𝗲𝗿 𝗧𝘄𝗶𝗰𝗲
A support agent at a mid-size company once told me she'd typed the same answer to the same question so many times she could do it in her sleep.
Every day, another version of that question. Until one day, someone finally asked why a person was doing it at all.
That's usually where I come in. Not with a pitch about AI. With a question about the thing nobody's counted yet.
𝙒𝙝𝙖𝙩 𝙔𝙤𝙪 𝘼𝙘𝙩𝙪𝙖𝙡𝙡𝙮 𝙉𝙚𝙚𝙙 (𝙄𝙩'𝙨 𝙋𝙧𝙤𝙗𝙖𝙗𝙡𝙮 𝙉𝙤𝙩 "𝘼𝙄")
Most businesses that hire an AI developer don't need AI. They need one specific, annoying bottleneck to stop being their problem.
AI is just the tool. The bottleneck is the target. So before anything technical happens, I spend time finding that target. Not guessing at it. Finding it.
𝙏𝙝𝙚 𝘾𝙖𝙩𝙝𝙚𝙙𝙧𝙖𝙡 𝙋𝙧𝙤𝙗𝙡𝙚𝙢
I think about a fine-tuned model a little like a cathedral.
Medieval builders didn't just stack stone into a big room. They shaped the walls and ceiling so a single voice at the altar would carry clearly to the last pew, without turning into noise along the way.
Most AI systems fail for the same reason bad architecture fails. They add noise instead of shaping signal. My job is building the room so the model's answer comes out clear, on tone, and grounded in what's actually true about your business.
𝙃𝙤𝙬 𝙄 𝘼𝙘𝙩𝙪𝙖𝙡𝙡𝙮 𝘽𝙪𝙞𝙡𝙙 𝙏𝙝𝙞𝙨
I build production LLM systems end to end: model selection, fine-tuning, evaluation, deployment, and continuous optimization after launch. A system that holds up under real traffic.
𝐅𝐨𝐮𝐧𝐝𝐚𝐭𝐢𝐨𝐧 𝐌𝐨𝐝𝐞𝐥𝐬
I work directly with transformer-based foundation models using PyTorch, Hugging Face Transformers, and CUDA-accelerated training, choosing architecture based on your latency budget and data volume rather than defaulting to whichever model is trending.
𝐅𝐢𝐧𝐞-𝐭𝐮𝐧𝐢𝐧𝐠: LoRA and QLoRA for efficient adapter training, full fine-tuning when the use case genuinely justifies the cost, and domain adaptation so the model speaks your business, not generic internet text
𝐏𝐫𝐞𝐟𝐞𝐫𝐞𝐧𝐜𝐞 𝐎𝐩𝐭𝐢𝐦𝐢𝐳𝐚𝐭 RLHF and preference-tuning methods so the model's judgment, not just its facts, matches how your team actually makes decisions
𝐐𝐮𝐚𝐧𝐭𝐢𝐳𝐚𝐭𝐢𝐨𝐧: compressing models for cheaper, faster inference without losing the accuracy that makes them worth deploying
Inference: serving infrastructure built for real throughput, not a single-request demo
𝐑𝐞𝐭𝐫𝐢𝐞𝐯𝐚𝐥 𝐒𝐲𝐬𝐭𝐞𝐦𝐬
Retrieval augmented generation (RAG) grounds answers in your actual documents instead of the model's memory, using vector databases like Pinecone, Weaviate, or pgvector.
The part almost nobody talks about publicly: a bad embedding model will confidently retrieve the wrong document, and the language model will trust it completely, the same way people trust anything that simply sounds authoritative. I spend real time on embedding selection and chunking strategy before a single generation prompt gets written, because that's where most RAG systems actually succeed or fail.
𝐕𝐢𝐬𝐢𝐨𝐧
Computer vision systems for detection, classification, and embedding-based visual search at scale, and diffusion model work for generative image pipelines when the use case calls for it.
𝐌𝐮𝐥𝐭𝐢-𝐀𝐠𝐞𝐧𝐭 𝐒𝐲𝐬𝐭𝐞𝐦𝐬
Multi-agent orchestration using frameworks like LangGraph, where a planner, a retriever, and a checker each handle their own piece of a workflow instead of one model trying to be everything at once. A single model attempting to plan, search, reason, and respond in one pass is a bit like one musician trying to play an entire orchestra alone. Technically there's sound. It isn't music.
𝐃𝐞𝐩𝐥𝐨𝐲𝐦𝐞𝐧𝐭 𝐚𝐧𝐝 𝐌𝐋𝐎𝐩𝐬
A model sitting in a notebook is a research project. A model wrapped in a monitored, logged, rollback-ready API, with proper MLOps around training runs and versioning, is a product people can actually rely on.
Cost-per-request monitoring, since an ungoverned AI bill is one of the fastest ways a promising pilot gets killed by finance
Model evaluation pipelines tracking hallucination rate, latency, and cost as three separate numbers, catching regressions before your users do
Guardrails and human checkpoints wherever a wrong answer is expensive: financial figures, customer-facing decisions, anything hard to undo
Multimodal AI integration when a project needs text, vision, and structured data working together, not in isolation
A model that sounds confident and is wrong causes more damage than a model that simply admits it doesn't know. I'd rather ship the one that knows its own limits.
𝐇𝐨𝐰 𝐈 𝐖𝐨𝐫𝐤 𝐖𝐢𝐭𝐡 𝐏𝐞𝐨𝐩𝐥𝐞
I ask more questions upfront than most freelancers bother to. Not to stall, but because a model trained on a misunderstood problem is expensive to unwind later. Retraining isn't like fixing a typo.

Licensed Medical Doctor + Top Rated AI Engineer (100% JSS, $30K+ earned on Upwork). I build LLM agents, RAG systems, and healthcare automations that ship.
Most AI freelancers can write code. Very few can sit in a clinical handover, read a messy guideline PDF, or map a patient-intake workflow — and then build the system that automates it. That's the gap I fill: a practicing physician with 5 years on Upwork delivering data and AI projects for US and UK clients.
WHAT I BUILD
- LLM agents & multi-agent systems — LangGraph, Google ADK, OpenAI/Anthropic/Gemini APIs
- RAG & document Q&A — LlamaIndex, ChromaDB, with PHI redaction (Microsoft Presidio) for sensitive data
- AI voice agents — appointment booking, intake, lead qualification
- Workflow automation — n8n, Make, Zapier + custom Python/FastAPI glue
- Medical imaging AI — PyTorch fine-tuning of vision foundation models (LoRA/PEFT)
- Data analytics & dashboards — Python, SQL, Tableau, Excel (where I started; still sharp)
WHY THE "MD" MATTERS TO YOUR PROJECT
- Healthcare builds: I understand clinical context, terminology, and PHI handling by training — compliant-by-design, not patched later.
- Any build: medicine trains you to work under pressure with zero tolerance for sloppy errors. I check my work the way I check a drug dose.
- Research rigor: first-author research on TB detection from chest X-rays using parameter-efficient fine-tuning of vision foundation models [FILL: "accepted at" or "under review at" MICCAI 2026 workshop — state it accurately].
RECENT WORK
- Multi-agent clinical decision support assistant (Google ADK + Gemini) — [FILL: 1-line outcome]
- PHI-safe RAG Q&A over clinical guidelines — [FILL: 1-line outcome]
- Massive-scale computer-vision data annotation for Adobe — [FILL: 1-line outcome, e.g. volume/accuracy]
HOW I WORK
- Working prototype early — usually within the first week, so you see progress, not promises
- Clear milestones, async updates, full documentation + handover video at the end
- 4+ hours of daily overlap with US/UK time zones; average response under 4 hours
- If your project isn't a fit, I'll tell you on day zero and point you in the right direction
Message me with what you're trying to build or automate. I'll reply with whether I can help, how I'd approach it, and a realistic estimate — no fluff.
