Chemical Engineering

I have a Master's degree in Chemical Engineering and graduated Summa Cum Laude from my Bachelor's. I have been a teaching assistant in courses such as Chemical Kinetics and Reaction Engineering and have privately tutored subjects such as Thermodynamics, General Chemistry, Physics, Calculus, Differential Equations, etc. I have a passion for teaching and helping students unlock their potential and find success.

Real Estate

Real Estate

I worked as a licensed real estate agent with Keller Williams, gaining hands-on experience in contracts, transactions, and property analysis. My strongest specialty is real estate math, including commissions, interest calculations, property taxes, and investment returns. I break down concepts clearly and provide step-by-step guidance so students can master both the math and the practical side of real estate. Whether you are preparing for the licensing exam or just want to improve your real estate knowledge, I can help you succeed.

Thermodynamics

I hold a B.S. and M.S. in Chemical Engineering and have tutored university-level Thermodynamics for 7+ years. I help ChemE/ME/Physics students master the first and second laws, state properties & EOS (ideal/real gases, compressibility), entropy/enthalpy, phase equilibria, and power/refrigeration cycles (Rankine, Brayton). My sessions are step-by-step: we derive key relations, read property/steam tables confidently, and then drill exam-style problems until the method sticks.

Very professional and knowledgeable tutor.

Alejandro was very knowledgeable and professional and was quickly able to assess my 14 year old son’s mathematical level and needs. My son is shy and doesn’t easily warm up to people, but Alejandro made learning fun, easy, and approachable. So happy we found him! I would 10/10 recommend him for all your SAT math needs.

Patient helpful tutor

Alejandro was an awesome tutor. He looked over the assignment I needed help with well before starting our lesson to be sure he knew how to properly explain it to me. He was very patient and helpful with explaining the topics that I was struggling with. I would certainly recommend Alejandro for anybody looking for help with physics.

Knowledgeable and helpful tutor.

We worked on forces, he was able to help me understand the 4 lessons we were supposed to learn over 2 weeks in just 2 hours!! Would recommend him for AP Physics 1 tutoring.
