Being artistic with words is my solution to everything, it’s my gushing purpose to earn a living. To observe, to jot down, to form, to be astounded at nothing, to treasure the eccentricities, to let nothing go down the drain, to make something, to make a great flower out of life, even if it’s a cactus. Words have enchanted, educated, and inspired me since I was a child, which is why I love working with clients to help their words have the greatest possible impact on their audience. I am an expert at connecting brands with consumers. If you really want to hire a fantastic candidate, expand brand awareness, and breathe life into your project, then I’m your guy!! My experience as an educator allowed me to hone my problem-solving skills for myriad young people and adults. I have worked with well-known international companies helping them to achieve their creative goals: ✅ Texts for advertising purposes (handbooks, case studies, blogs, landing pages, social media, ads, and web content), ✅ to literary creations (plots for movies, short stories, scripts, poems, novels) that make readers’ imaginations take flight. My Creativity and Graphic Skills will undoubtedly offer you a clear, impactful, and entertaining copy. Other areas of expertise include: ✔ Business Proposals and Plans ✔ Thesis and Research Writing ✔ IBM SPSS Data Analysis ✔ Academic Writing Tasks ✔ Proofreading and Editing I'm known for my ability to edit texts quickly while catching the mistakes and areas of weakness that others overlook. I am a passionate perfectionist when it comes to a succinct, well-written, and error-free document. TRY ME and you won’t be saddened. But don’t just take my word for it. Here is an example of what my clients have said: “Zohaab worked quickly. He clearly wanted me to be happy with the work he completed. He is extremely pleasant and positive. He writes content and copywriting. It is a good idea to reach out to Zohaab. You will enjoy working with him since he is a hard worker” ~ Mindy S. ~

i have 13 years diverse experience as a process Engineer in design and rating of equipment used in process industry like Heat exchangers, Fired heaters, pumps, compressors, evaporators, vacuum filters, filter press, crystallizers, distillation columns, liquid-liquid extractors, reactors, separators etc. Simulation of any type of process is not only my profession but my passion too, i am well conversant with application of material and energy balances over any given processing system. in addition i am acquainted of solving all those problems including heat transfer, chemical reactions, engineering thermodynamics etc. i have hand on experience of using different commercially available software for simulation of steady and dynamic process, pipe hydraulics, design and rating of heat exchangers, safety analysis and pinch technology.
A process engineer is a chemical or industrial engineering specialist who designs, optimizes, and troubleshoots manufacturing and production processes to improve efficiency, safety, yield, and cost. Hiring a freelance process engineer gives you on-demand access to the technical expertise needed to scale up production, reduce waste, validate equipment, and bring new products from lab bench to commercial output.
Process engineers convert raw materials into finished products by engineering the systems that handle reactions, separations, heat transfer, and material flow. They translate process requirements into piping and instrumentation diagrams, mass and energy balances, equipment specifications, and operating procedures.
On Freelancer.com, businesses hire process engineers for a wide range of work spanning chemical, pharmaceutical, food and beverage, oil and gas, mining, water treatment, and manufacturing operations. The commercial value is direct: a well-engineered process reduces utility consumption, increases throughput, lowers reject rates, and shortens commissioning time.
The deliverables depend on the project stage, but typical outputs from a process engineering specialist include:
Strong candidates demonstrate fluency with the simulation, drafting, and analysis tools that define modern process engineering work. Expect to see proficiency in:
Process engineering expertise is needed across asset-intensive and product-driven sectors. Common engagements come from:
Process engineering is a credential-heavy field, and the wrong hire can lead to safety incidents, failed commissioning, or expensive redesigns. Look for candidates with a degree in chemical, process, or industrial engineering, professional registration (PE, CEng, or equivalent) where applicable, and direct industry experience aligned with your sector. Portfolio markers to look for include sanitized P&IDs, simulation case studies, HAZOP facilitation experience, and documented scale-up or debottlenecking projects.
Sample interview questions you can use directly:
Process engineering projects rarely sit in isolation. Depending on the scope, you may want to combine your hire with freelancers in mechanical engineering, instrumentation and control systems, electrical engineering, piping design, structural engineering, environmental engineering, and project management. For regulated industries, technical writers experienced in validation protocols and CAD drafters skilled in 3D plant modeling are common companions.
Freelancer.com gives you access to a global pool of qualified process engineers, from independent consultants with decades of refinery and pharmaceutical experience to early-career engineers proficient in modern simulation tools. You can post a project on Freelancer.com and receive competitive bids from specialists across multiple time zones, which is particularly valuable for projects requiring round-the-clock progress or local regulatory knowledge. Clients set their own budgets and review verified portfolios, ratings, and completed project histories before awarding work, and Milestone Payments protect funds until deliverables are accepted.
Hiring a process engineer through Freelancer.com is straightforward when your brief is technically specific. The clearer your scope, deliverables, and existing data, the higher the quality of the proposals you receive. Below are the three steps to follow.
The project brief is the single biggest determinant of bid quality. A precise, technical brief filters for engineers whose discipline experience genuinely matches your problem, whether that is sizing a distillation column, validating a clean-in-place system, or running a HAZOP. Head to the
Bids on a process engineering project are short technical proposals, not just price quotes. A strong bid shows that the engineer has read the brief, understands the chemistry or unit operation involved, and has a clear methodology. Use Freelancer.com's chat feature to ask clarifying questions before shortlisting.
The final decision combines proposal quality with profile evidence. For process engineering, consistency matters more than a single impressive case study, because the work demands repeatable rigor across calculations, drawings, and safety reviews. Examine each shortlisted freelancer's profile carefully before awarding.
Timelines vary widely with scope. A focused calculation, equipment sizing, or simulation review can be completed in days, while a full FEED package, HAZOP, or commissioning support engagement typically runs several weeks to several months. Define your milestones in the brief so freelancers can quote a realistic schedule.
Yes. Many clients use Freelancer.com for discrete deliverables such as a single P&ID, a pressure relief sizing study, a debottlenecking analysis, or a HAZOP facilitation. Freelancers are accustomed to fixed-scope engagements and will scope deliverables, assumptions, and revision rounds in their proposal.
The two terms overlap heavily. Chemical engineering is the academic discipline, while process engineering is typically the applied role focused on designing and operating production processes. In practice, most freelance process engineers hold chemical engineering qualifications, and the titles are often used interchangeably in industry.
For defined deliverables, simulations, calculations, optimization studies, and design reviews, a freelance process engineering expert is usually faster and more cost-effective. For multi-discipline EPC projects with hundreds of drawings and field execution, a full engineering firm is appropriate. Freelancers also work well as independent reviewers or specialist support to in-house teams.
Yes. Process work often involves proprietary recipes, plant data, and trade secrets. Freelancers on Freelancer.com routinely sign non-disclosure agreements before receiving sensitive technical documentation, and you can require an executed NDA as a condition of awarding the project.
