About · Engineer–Builder–Founder

Industrial Engineer. Software Builder. Founder.

The orientation is toward real-world systems where operations, maintenance, and information flow determine outcomes. The approach is capability stacking: engineering knowledge, software construction, and market execution inside one loop — built deliberately, not by accident.

The foundation is power generation engineering — eight years inside operational environments: combined cycle plants, HFO power plants, and gas-based generation facilities. Academic background in electrical engineering at diploma level, followed by self-directed learning across mechanical, chemical, and software engineering.

"Replace manual processes, undocumented workflows, and fragmented tools with structured digital infrastructure."

Three PillarsIndustrial Engineering · Software Development · Digital Marketing

Pillar I

Industrial Engineering

Understanding of operational environments in power plants and asset-heavy facilities — from the inside. Not theoretical process diagrams but how engineers actually execute work: maintenance management, outage planning, permit-to-work safety systems, technical reporting, equipment reliability monitoring, and operational compliance documentation.

Pillar II

Software Development

Full-stack software development focused on operational systems rather than generic applications. The design philosophy is operational modeling — software must represent real actions performed by engineers, operators, administrators, and managers. Converting undocumented organizational knowledge into structured digital systems.

Pillar III

Digital Marketing & Growth

Combining systematic marketing with engineering excellence. Expert in Technical SEO, programmatic campaigns, search intent analysis, copywriting, conversion optimization (CRO), Meta/LinkedIn/Google Ads, newsletter growth, and B2B SaaS go-to-market strategies.

Operating Principles How every project, product, and system gets built

Operational Modeling

Software must represent how work actually gets done — not how a project manager imagines it gets done. Every system starts with how engineers, operators, and administrators actually execute their jobs.

II.

Capability Stacking

Engineering knowledge, software construction, and market execution inside one loop. Each capability multiplies the others. An engineer who can build and distribute is fundamentally different from one who can only do one.

III.

Structured Over Fragmented

The goal is always the same: replace manual processes, undocumented workflows, and fragmented spreadsheet-based tools with structured, repeatable, and scalable digital infrastructure.

IV.

Distribution Ownership

Building a product without controlling its distribution is half a business. SEO, paid advertising, and email systems are built in-house — the same engineering discipline applied to market execution.

Flagship · Cloud CMMS & Operational ERP

Wrysto

Cloud-based CMMS and operational ERP platform designed for power plants and asset-heavy industries. The system focuses on operational execution rather than finance-centered ERP design — built by someone who has spent years inside these environments. Targets power plants, pharmaceutical manufacturing, textile factories, and industrial facilities replacing spreadsheets and fragmented reporting systems.

Core functions: technical reporting automation, maintenance scheduling, role-based work order management, outage tracking, permit-to-work workflows, and operational compliance management.

Venture · Technical Publishing

Technical Publishing

A professional initiative publishing practical engineering books and manuals. The flagship book **"Power Plant: Theory That Matters on the Job"** helps graduate engineers, operators, and maintenance professionals understand not just *what* happens in plants, but *why* and *how* that knowledge applies on the job.

Venture · Education & Insights

Engineering Education

An educational platform designed to share real-world engineering articles, resources, and courses. Focuses on what engineers actually use inside industrial facilities rather than theoretical math. It is paired with the Megawatt Insights Substack newsletter.

Career PathFrom plant floor to software founder

Development Path

Engineering practice → software development → market execution. Each step was deliberate. The goal was always to encode operational knowledge into systems that other people and industries could use.

2019 — Present

Power Plant Engineer

Energy Generation · Gazipur, Bangladesh

Eight years of 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 study in mechanical and chemical engineering. Exposure to maintenance management, permit-to-work systems, outage planning, technical reporting, and operational accountability structures.

Parallel Path

Software Developer

Self-Directed · Full-Stack

Moved from engineering practice toward software development to encode operational knowledge into digital systems. Built full-stack capability with Next.js, TypeScript, Prisma ORM, Postgres (Neon serverless), Clerk, FastAPI, and LLM integration for workflow automation. Design philosophy: operational modeling — software that represents how engineers actually work.

Parallel Path

Digital Marketing Practitioner

B2B & Service Businesses

Built distribution capability to control the customer acquisition layer for digital products and services. SEO, Meta advertising, LinkedIn advertising for professional audiences, email marketing funnels, landing page optimization, and lead generation systems — all built in-house to eliminate dependence on external agencies.
