MEP engineer with 15+ years in mechanical, electrical and plumbing design — 130+ contracts delivered here on Upwork at 100% Job Success, Top Rated, plus 100+ MEP projects beyond the platform, including 50+ approved plans in California. I produce permit-ready MEP plans and calculations for US residential and light-commercial projects, in all 50 states. Most of what I do is one of three things: a load calculation package for a permit, a complete MEP drawing set, or taking a set somebody else started and making it coordinated, code-compliant and ready for plan check.

What I do is the engineering — the calculations, the drawings and the permit package, built to the code your jurisdiction has actually adopted. Where your permit office requires a seal, a US-licensed PE stamps the set: in-house for Texas and California, and through licensed partner engineers in other states. I coordinate that, it usually adds only a few days, and the stamping is priced into the quote before work starts rather than appearing later. My own credentials: BSc in Electrical Engineering (2011), assessed as an Engineering Technologist by Engineers Australia, and a Member of the Institute of Engineers, Bangladesh (MIEB). 15+ years in MEP design across residential, commercial and industrial work.
