Roshan C
About this gig
Stop getting generic, unreliable outputs from ChatGPT and AI tools.
Whether you need a specialized Custom GPT for your business, an automated internal AI assistant, or razor-sharp system prompts, I construct layered AI instructions designed for accuracy, brand voice, and real-world results.
What I Can Build For You:
- Custom GPT Creation: Tailored OpenAI GPTs pre-loaded with custom knowledge bases, guidelines, and behavioral guardrails.
- Advanced Prompt Engineering: Structured multi-shot, persona-based, and chain-of-thought prompts that eliminate generic AI fluff.
- API & Action Configuration: Connecting your Custom GPT to external webhooks, Zapier, or custom endpoints.
- Testing & Benchmarking: Stress-testing prompts against edge cases to prevent hallucinations and maintain output quality.
Why Work With Me?
I don't just paste generic text into ChatGPT. I treat prompt engineering like functional software architecturefocusing on structured variables, logical constraints, and reproducible results.
Please send me a message prior to ordering so we can evaluate your data sources, target platform, and technical goals!

I am a Game Writer and Designer currently pursuing an Advanced Diploma in Game Programming. My background includes postgraduate studies in Screenwriting and Narrative Design, focusing on creating immersive narratives. I have experience collaborating with designers to integrate compelling stories into game environments and refining character arcs through 'show, don’t tell' principles.
FAQ
Do I need a ChatGPT Plus account for a Custom GPT?
Yes, to use and edit Custom GPTs inside OpenAI's interface, a ChatGPT Plus/Team subscription is required. If you use the OpenAI API instead, no subscription is needed
Can you train the GPT on my company's specific documents?
Absolutely! I can structure and optimize your PDFs, text files, SOPs, and spreadsheets so the GPT accesses accurate information without hallucinating.
What if the AI generates incorrect answers (hallucinations)?
I program strict guardrails and fallback instructions into the system prompt (e.g., "If the information is not in the provided document, state that you do not know"), minimizing incorrect outputs.
