A senior engineer on subscription. I build your features, clean up older code that's slowing the product (tech debt), and ship in 2-4 day cycles. No hiring, no contracts, cancel anytime.
This works best if you're…
The subscription model is designed for specific situations. Here is where it shines.
Startups post-fundraise
You've raised, your first working version (MVP) is live, and now you need a reliable engineer to ship features fast without breaking what's working.
Scale-ups with older code slowing the product
Your product grew fast and the codebase is suffering for it. You need someone to clean it up (pay down tech debt) while keeping the business moving.
Founders without in-house dev
You need a senior engineer who can own the entire technical side: architecture decisions, vendor selection, and all the code.
Teams with a backlog problem
You have more tasks than your team can handle. I plug in, take ownership of a stream of work, and make the backlog move.
How it works
A simple three-step path from first conversation to shipping.

Subscription vs. hire vs. agency
How the subscription model compares to a full-time hire or a typical agency.
| Factor | Full-time hire | Agency | Subscription |
|---|---|---|---|
| Monthly cost | $6,000–$10,000+ | $10,000–$25,000 | $4,999–$6,999 |
| Time to start | 3–6 months | 2–4 weeks | 1–2 weeks |
| Contract flexibility | Long-term commitment | Project-bound | Cancel anytime |
| Communication | Direct | Account manager | Direct (Slack/Trello) |
| Senior-level code | Depends on hire | Varies by team | Me, every time |
| IP ownership | Employer owns | Varies by contract | 100% yours immediately |
Why I Might Not Be a Good Fit
Transparency matters. This way of working is not for everyone. Here is when I might not be the right fit.
Daily stand-ups required
You require daily stand-ups or very frequent synchronous check-ins.
Hourly invoicing needed
You need detailed hourly invoicing or line-item breakdowns for accounting.
Large on-site team needed
You need a large, on-site team dedicated full-time to a single project.
One-off task only
You need a single quick task, not an ongoing partnership or subscription.
Your questions answered
Common questions about the subscription model and how I work with you.
I do not bill by the hour, and I do not track hours. My focus is on delivering results at a consistently high level of quality. A fixed monthly fee provides predictability and aligns my incentives with yours: faster, better delivery benefits you. Every subscription includes a 14-day money-back guarantee, full refund if you are not satisfied in the first two weeks, no questions asked.
On the Standard plan, I schedule an alignment call with you every two weeks. On the Pro plan, I meet with you weekly. Between calls, you have direct access via Slack or Trello for questions and updates. I respond within 24 business hours (and usually much sooner).
Yes. You may pause when needed, for example during a slow month or when you are on vacation. Unused days in your current billing cycle are saved as credit for when you return. There are no long-term contracts; renewal is monthly.
That is perfectly fine. Record a short video using Loom or another tool and share it with me. I value context and clarity. If something remains unclear after reviewing your materials, you and I can schedule a brief call as needed.
There are two subscription tiers: Standard ($4,999/mo) for maintenance and feature development, and Pro ($6,999/mo) for higher delivery velocity and more complex systems. Both are month-to-month retainers with no long-term contracts.
There is no minimum commitment. Subscriptions are billed monthly and you can cancel anytime. Every subscription includes a 14-day money-back guarantee, full refund if you are not satisfied in the first two weeks, no questions asked.
Typically about one week. I start with a discovery call, review your codebase and backlog, confirm priorities, and begin the first task cycle within a few days.
The subscription works alongside your existing team. I can take ownership of a dedicated stream of work, review code from junior developers or third-party vendors, and provide architectural guidance without disrupting your team's workflows.
Application case studies
See how I have shipped software that handles real production load.
Built and shipped an investor-ready MVP from scratch
GigEasy — backed by Barclays · Bain Capital · Zean Capital Partners
Built the entire technological base and delivered MVP in just 3 weeks, enabling a successful rapid launch and investor demo.
Adriano brings the experience of a seasoned developer who has built systems at scale and learned to avoid common pitfalls. If you're looking for someone with the expertise to build at scale and the wisdom to do it right, I highly recommend Adriano.— Gabriel Edlin, Ops/Strategy, GigEasy

Four systems, one source of truth: HubSpot visibility for one of Brazil's largest vet networks
Built a custom integration layer for Reevia that connects four source systems into HubSpot for one of Brazil's largest veterinary companies. Over 2 million records processed with full normalization. Any lead from any system is inside HubSpot in under 50 seconds, standardized and ready to use.
For the first time, our teams all work from the same data. The integration runs silently in the background and just works.— Reevia
A custom CRM that turned Google Maps into a lead machine
Built a purpose-built CRM for a digital agency that captures leads from Google Maps, reaches them via official WhatsApp (Twilio + Meta API), and uses AI to suggest replies and standardize templates. The system scaled the lead base by over 500%, with 250 new leads entering the pipeline every day.
250 leads a day. We could never do that manually.— Norte Web Digital
Rescued a slow API that was blocking user growth
Cuez by Tinkerlist — backed by Tinkerlist group (Belgium)
Cuez is a live broadcast production tool used by TV teams on air across Europe. I inherited a backend API averaging 3 seconds per response and cut it to 300ms, while reducing infrastructure costs by 40% and leaving the system stable under real production load.
Always with many ideas to add and open to discuss the best approach to create the most scalable software as possible.— Rafael Camillo, Senior Software Engineer, Cuez by Tinkerlist
Unified payment orchestration across Asia and Europe

Rebuilt a real estate portal at a fraction of the cost
Rebuilt Imóveis SC's real estate portal as ImoHub, a faster, more scalable successor, handling 120k+ properties with sub-second search and drastically reduced AWS costs.
Security & Legal Protection
Your business and IP are protected through standard subscription agreements designed for ongoing engineering partnerships.
One simple contract covers all the work
A single Master Services Agreement (MSA) covers every subscription period. No new paperwork for each project. Quick to sign, protects both sides.
I invoice you as a US business
Contracts run as B2B, not employment. Keeps taxes and billing clean on both ends, and you won't get flagged for treating a contractor like an employee (IRS/IR35 safe).
Once you pay, everything is 100% yours
Code, architecture, assets. I keep nothing. Written into the contract as a Work Made for Hire clause, effective the moment payment clears.
Confidentiality (NDA)
Standard Non-Disclosure Agreement built into the terms. Your trade secrets, data, and business logic stay private.
