Process engineering that holds up under real-world scrutiny.
I’m Hira, a chemical engineer helping U.S. companies and startups turn process concepts into calculated, documented, buildable designs — from mass and energy balances to full P&ID packages.
Engineering services built for teams that need it done right the first time.
From early-stage concept work to detailed documentation ready for procurement and construction, I provide the calculations, drawings, and reports process-driven businesses rely on.
Process Design & Simulation
Mass and energy balances, equipment sizing, and full process simulations built to match your real operating conditions — not textbook assumptions.
- Steady-state process simulation
- Equipment sizing & specification
- Heat and material balance sheets
P&ID and PFD Development
Clean, standards-compliant process flow diagrams and piping & instrumentation diagrams that your team, vendors, and regulators can actually read.
- PFDs with full stream data
- P&IDs to ISA/ANSI conventions
- Redlines and as-built updates
Technical Documentation
Engineering reports, feasibility studies, and design basis documents written for both technical reviewers and non-technical stakeholders.
- Feasibility & concept studies
- Design basis & datasheets
- Signed engineering reports and affidavits
Equipment & Utility Sizing
Sizing calculations for reactors, columns, heat exchangers, pumps, and utility systems, backed by first-principles engineering — not rules of thumb alone.
- Heat exchanger & column sizing
- Pump & piping calculations
- Utility and HVAC load estimates
HSE & Compliance Support
Process safety documentation and compliance-oriented reviews that help your project stand up to client, insurer, and regulatory review.
- HAZOP & process safety input
- Environmental compliance reports
- Standard operating procedures
Project & Freelance Engineering Support
Flexible engagement for startups, EPC firms, and platform-based clients who need reliable engineering capacity without a full-time hire.
- Commercial freelance project delivery
- Short-term technical consulting
- Ongoing retainer-based support
Industry-standard tools, used the way industry actually uses them.
Every deliverable is produced in the software your engineering and procurement teams already expect — no unfamiliar formats, no translation layer.

A streamlined process, from first message to final delivery.
Every project follows the same disciplined process — so you always know what’s happening, what’s next, and when to expect it.
You reach out
Send a message through the contact form or email with a short description of your project. I respond promptly, typically within one business day.
We discuss requirements and details
We go through your project scope, constraints, and goals together, so the engineering work is built around what your project actually needs.
Analysis of the project and requirements
I review the technical details, existing data, and any documentation you provide, and identify what’s needed to complete the work accurately.
Proposal and estimated timeline
You receive a clear, itemized proposal covering scope, deliverables, cost, and a realistic delivery timeline — no vague estimates or open-ended scopes.
Project kickoff after approval
Once the proposal is approved, work begins immediately according to the agreed plan and milestones.
Regular updates and revisions
You receive progress updates at defined checkpoints, with room for feedback and revisions built into the process — not treated as an afterthought.
Final delivery
Completed deliverables are packaged, documented, and handed over professionally, ready for internal use, procurement, or regulatory submission.
Five-plus years of engineering experience, built on real commercial work.
My background spans structured engineering roles and commercial freelance delivery, giving me both the technical foundation and the client-facing experience to manage projects independently from start to finish.
I’ve delivered process design, documentation, and technical consulting for clients across freelance platforms and direct engagements, primarily supporting businesses in the United States.
Freelance platform experience
Remote collaboration
US client communication standards
Engineering rigor, delivered with clear communication.
“Every value is independently calculated for the project at hand — no recycled numbers from a previous job, no shortcuts on the fundamentals.”
“Clear proposals, defined timelines, and steady updates mean clients always know exactly where their project stands.”
“Deliverables are formatted and packaged the way U.S. engineering, procurement, and review teams expect to receive them.”
