Profile · Engineer–Builder–Founder
The foundation is power generation engineering — five and a half years inside operational environments: combined cycle plants, HFO power plants, gas-based generation facilities. That time produced something more valuable than a CV line. It produced an understanding of how industrial systems actually run: maintenance cycles, outages, permit systems, reporting structures, and the operational accountability that keeps megawatts flowing. From that foundation, two additional capabilities were built deliberately — software development to encode operational knowledge into digital systems, and digital marketing to control the distribution layer of those products.
The current focus is Wrysto — a cloud-based CMMS and operational ERP platform built for power plants and asset-heavy industries. Alongside that: a doctor digital presence platform serving healthcare professionals in Bangladesh, a school management software in development, and an engineering knowledge platform designed to help graduates understand how real industrial systems function. The orientation throughout is the same — replacing manual processes, undocumented workflows, and fragmented tools with structured digital infrastructure.
Flagship Product · SaaS
Cloud-based CMMS and operational ERP platform designed for power plants and asset-heavy industries. The system focuses on operational execution rather than finance-centred ERP design — built by an engineer who has lived inside these systems.
Target Industries
Venture · Professional Services
Specialized website solutions for healthcare professionals in Bangladesh — dentists, eye specialists, and clinic owners. Establishing professional digital identity, increasing patient trust, and improving visibility in local search results. Positioned for a market that needs simpler digital systems with strong demand.
Venture · EdTech
Digitizing school administration for educational institutions still relying on manual paperwork. Modules: student database, attendance tracking, exam and result management, fee management, teacher administration, parent communication, and academic reporting dashboards.

Industrial engineer. Software builder. Digital entrepreneur. Each capability was built deliberately to close a loop — from understanding how systems work, to encoding them in software, to getting that software in front of the people who need it.
2019 — Present
Energy Generation Sector · Gazipur, Bangladesh
Operational experience across combined cycle plants, HFO power plants, and gas-based generation facilities. Hands-on with Wärtsilä 18V50 HFO engines, INNIO Jenbacher gas engines, EGB systems, and TUBAIN generators. Diploma in electrical engineering; self-directed learning across mechanical and chemical engineering relevant to power generation.
Ongoing
Independent · Remote
Building operational software systems with Next.js, TypeScript, Prisma ORM, Postgres (Neon serverless), Clerk authentication, FastAPI, and LLM integration. Design philosophy: operational modeling — software must represent real actions performed by engineers, operators, administrators, and managers, not generic CRUD abstractions.
Ongoing
Wrysto · Doctor Digital Platform · School Software
Building specialized SaaS tools for industrial sectors, digital presence platforms for healthcare professionals in Bangladesh, and school management software for educational institutions. Distribution through SEO, Meta advertising, LinkedIn advertising, email funnels, and landing page optimization — without dependence on external marketing agencies.
Ongoing
Substack · yasirarafin.com
Weekly newsletter on power plant engineering and digital transformation in engineering industries. In parallel: developing a book and structured learning content focused on real plant operations — helping engineering graduates understand how industrial systems actually function, rather than theory alone.
