Chemical Engineer Building Custom Formulation & Process Tools

I'm a biochemical engineer who builds reactive HTML modelling calculators that tell food, supplement, cosmetic, and botanical founders what their next decision should actually be, instead of what a spreadsheet someone else built says it should be. Ten years as a free agent. 200+ projects shipped. $1.5M in direct contracts. ~$10M in documented client value across CPG, nootropics, frozen desserts, ingredient extraction, herbal and botanical formulation, and cosmetics. MSc in Biochemistry, six years in academia before that. That's how I know the difference between math that decides and math that impresses. Where my work tends to land: 🧊 Popsicles, frozen desserts, ice pops. Stabilizer system balance (xanthan, guar, LBG), sugar and syrup ratios, freezing-point depression, ice-crystal control, freezer-cabinet stability windows. Reactive formulators with every range hard-stopped to published literature. 🥤 Protein bars, protein beverages, protein isolates. Whey, casein, pea, soy, and hydrolysate selection. Sweetener and bitterness profiles, per-serving cost, label-claim feasibility, extraction yield, COGS per kilo, and breakeven curves across production scales. My protein-isolate model is used by clients across the agro-extraction industry to size processing lines before committing capital. 🌿 Botanicals and herbal products. Ingredient quality, MOQ math, supplier vetting, label compliance, formulation stability, extraction methodology. I also run a small herbal business myself, so I've felt every margin squeeze and ingredient-quote shock that clients bring to me. 💊 Supplements and nootropics. Claim feasibility, dose math, cost engineering, co-manufacturer scoping, channel-margin modeling. ✨ Cosmetics. Ingredient compatibility, parameter constraints, process simulation, scale-up math. 🛠️ What I actually deliver: A reactive browser-based calculator built around your real product, your real ingredient costs, your real production scale. Sliders for every variable that matters, with hard-stopped ranges grounded in published research. Plus the Excel back-end so your CFO can audit every formula. Plus a written diagnosis of what the numbers actually say. Plus implementation docs you can hand to your team. Typical turnaround: 5 business days for a tuned single-product engagement, 2 to 4 weeks for multi-product strategic models. Past custom engagements have run from $850 to $10,000, most landing in the $3,000 to $5,000 range depending on how many moving parts there are. 📊 Case study. David at Mora Cué Alimentos came to me with an equipment-selection question for a chia protein line. Three weeks later, with three product directions and three production scales modeled against real ingredient costs, channel margins, and capacity constraints, the answer was specific: protein concentrate at mid-scale, 41% gross margin. They built it. It works. 💬 What operators say: "Andres is very knowledgeable with great ideas and outstanding organizational skills." Cecilia Shepherd, CEO, Sound Science Nutrition "Andres was extremely helpful. I had a recipe emergency which he solved same day. I could go back to production with minimal disruption. Definitely will work again with him." Ismar Toromanovic, CEO, 3D Desserts "Andres is an outstanding chemist. I often cross-verify our models with his fundamental knowledge. I strongly recommend anyone looking for chemistry tutoring or overseeing complex calculations." Vishy Karri, CEO, Expert 365 "Congratulations on building this tool. It's really useful." David Olson, CEO, Mora Cué Alimentos ✅ A fit if you're a CPG, supplement, nootropic, cosmetic, or botanical founder at $1M+ in revenue or capital, making a real decision in the next 60 to 90 days. A co-man trial, an SKU launch, an ingredient swap, a scale-up. People tired of vibes-based pricing who want numbers they can defend in front of a board, a co-man, or a buyer. ⚠️ Probably not a fit if you're pre-revenue with a generic plan, shopping for the cheapest spreadsheet on the market, or looking for a formulator rather than a strategist. (I can refer you to good formulators if that's what you actually need.) Send me the decision you're sizing. If a model would help, I'll tell you. If it wouldn't, I'll tell you that too, in the first ten minutes.
