You will get A Technical Writer to deliver BRD, PRD..& API Docs your team can build from
Project details
Most startups hit the same wall: a great product idea, an eager development team, and zero documentation connecting the two. Developers start building on assumptions. Requirements change mid-sprint. Rework piles up. Deadlines slip. The problem was never the technology — it was the missing paperwork nobody wanted to write.
That's exactly what I fix.
I'm San — a senior Technical Writer and Product Leader with 20+ years translating complex product ideas into developer-ready documentation that engineering teams actually build from. I've written BRDs, FRDs, SRDs, PRDs, API documentation, user stories, and acceptance criteria for startups and enterprises across FinTech, Banking, Healthcare, EdTech, ERP, and SaaS — I write documentation that ships a product faster.
What makes my documentation different:
Every document I write is built for three audiences simultaneously — your business stakeholders who need to approve it, your developers who need to build from it, and your QA team who need to test against it. Most technical writers optimize for one. I write for all three, which means fewer meetings, fewer misunderstandings, and fewer surprises at the end of a sprint.

About Santonu
Fractional CTO, Enterprise PM| GenAI Workflow & LLM Integration Leader
100%
Job Success
Konnagar, India - 9:01 am local time
I operate as a Fractional CTO, Enterprise Product Owner, and AI-enabled delivery leader. My background includes 6 years embedded on-site in the USA partnering directly with tier-1 financial institutions, CEOs, and engineering VPs to ship highly compliant, scalable applications. I've led real GenAI feature builds for clients—taking LLM-powered capabilities from concept to production, not just advising on strategy.
My Upwork metrics demonstrate an essential asset:
5,800+ hours logged, with an exceptionally high average retention rate per client. I don't cycle through transactional tickets; I embed deeply into your organization to protect your technical roadmap and manage engineering floor velocity.
What you get from day one:
- Spec-Driven Execution: I use ChatGPT and Claude daily to translate complex, ambiguous product goals into developer-ready, markdown PRDs, architecture diagrams, and ironclad user stories—faster and with fewer revision cycles than manual spec-writing.
- GenAI Workflow Engineering: I've shipped LLM-orchestrated features using LangChain, LlamaIndex, and AutoGen, and I guide distributed dev teams in adopting this tooling to reduce rework and accelerate velocity. I use GitHub Copilot and Cursor directly to review and pressure-test dev output, so I validate delivery quality, not just manage it from a distance—I'm deepening this expertise continuously through structured GenAI/agentic AI training.
- Core Tech Stack & Legacy Modernization: I bridge the gap between heavy legacy systems and future-state, cloud-native microservices (.NET Core, Angular). I am a certified PowerBuilder Expert, specializing in migrating enterprise monoliths, DataWindows, and legacy databases safely to the cloud with zero operational downtime.
- Risk & Regulatory Governance: Backed by an M.Sc in IT, PMP, and SAFe certifications, I ensure your products meet strict security, compliance, and enterprise data-integrity standards.
Core Competencies:
Enterprise Cloud Architecture | Fractional CTO Leadership | Legacy to Cloud Migration (.NET Core, PowerBuilder) | GenAI Workflow Integration (LangChain, LlamaIndex, AutoGen) | AI-Assisted Delivery (ChatGPT, Claude, GitHub Copilot, Cursor) | Distributed Agile Operations (SAFe, Scrum) | High-Stake Stakeholder Alignment
Certifications:
PMP® | SAFe® POPM | CSPO | CSM | Sybase Certified PowerBuilder | Azure AI Certified (AI-900, DP-900)
Education: Master of Science in Information Technology (M.Sc IT)
Availability: Scalable advisory hours aligned across EST, PST, and EU time zones.
I partner best with founders, engineering directors, and investors who want a strategic thinking partner to de-risk their engineering execution — including the GenAI initiatives now central to product roadmaps. Let's connect.
Steps for completing your project
After purchasing the project, send requirements so Santonu can start the project.
Delivery time starts when Santonu receives requirements from you.
Santonu works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery — Understand Your Product & Documentation Needs
I start by reviewing everything you share — notes, wireframes, existing specs, or just a rough idea. I ask targeted questions to fill gaps before writing a single word. No assumptions made.
Structure — Define Document Framework & Outline
I build a clear outline for each document — sections, scope, and depth — and share it for your approval before writing begins. You know exactly what you're getting before I start
