SDVOSB government services for local, state, and federal agencies

Why do agencies contract with this SDVOSB?

Mango Consulting LLC is the legal entity. AppDesign360 is the operating brand for websites, mobile applications, and custom software. Both names refer to the same firm. This site is appdesign360.com. The firm was founded in 2018 by Manish Singh, a U.S. Army Veteran with dual graduate degrees (MPS and MSDS), and is operated by a service-connected disabled veteran.

The capability statement lists three certifications: Service-Disabled Veteran-Owned Small Business (SDVOSB), Minority-Owned Business, and Small Disadvantaged Business. We are registered in SAM.gov. CAGE code 87CG8. DUNS 116725856. Headquarters are in Queens, New York, with a service area in Teaneck, New Jersey. We support veterans employment and build technology teams that include veterans.

Published past performance includes the U.S. Department of Veterans Affairs (Data Science Technical Program Management), the U.S. Army Corps of Engineers (Economist, research support), and the Internal Revenue Service (Paralegal support). More of the company story is on the About page.

Federal contracting officers can use FAR Subpart 19.14 for SDVOSB sole-source and set-aside awards to an SBA-verified firm. The SBA describes the program on its SDVOSB contracting page. Local and state agencies buy the same services under their own procurement rules. A separate state veteran-owned certificate is a different credential from federal SDVOSB certification.

How does this SDVOSB deliver data analytics?

Data analytics at Mango Consulting LLC means database management, business analytics, support services, and a secure environment, tied to program and project management. The capability statement describes the company as one that identifies solutions from data-driven facts. The founder holds dual graduate degrees (MPS and MSDS), and VA past performance includes data science technical program management.

For an agency, a typical analytics engagement covers:

• Database management and the reports program staff actually use
• Business and operational analytics tied to a program metric
• A secure environment for the data the requirement names
• Hosting and data processing under NAICS 518210 when the work includes processing or hosting

Work begins with the decision the program must support, then the data required for that decision, then the report or model. The deliverable is that decision support.

How does this SDVOSB implement AI for government?

AI implementation is a defined build: select the workflow, connect it to systems the office already operates, and leave personnel able to run it. Automation is included where the requirement calls for it, as is the consulting that precedes installation. AI consulting on this site is the commercial form of that work, from $250 a session for a small organization. An agency requirement is quoted on its own scope.

Federal work is scoped to the security requirements in the contract. When the requirement calls for AWS GovCloud, Azure Government, or alignment with FedRAMP, ATO, or IL4/IL5, that constraint is part of the scope. Details of how we team on federal AI and software work are on the SDVOSB federal contracting page. We describe alignment with those environments. A product-level FedRAMP authorization is a separate status and is not claimed here.

What IT training does this SDVOSB provide?

Computer training is NAICS 611420. The capability statement places training with human-resource consulting: change enablement, training, and productivity. We also staff IT work and train the people who will keep a system running after acceptance.

Training engagements usually include:

• Hands-on sessions for the system or AI workflow we deliver
• Short operating notes the office can reuse after the class
• A train-the-trainer option when the agency wants its own staff to teach the next cohort

The objective is that agency personnel can perform routine tasks on the system after the course. Sustainment support, when required, is a separate line in the scope.

How does this SDVOSB support program management?

Program and project management on the capability statement sits with management consulting (assessment and process improvement) and with the data-analytics line. We manage to the scope, the schedule, and the budget the agency sets. VA past performance in data science technical program management is the closest published example.

A program-management engagement can include:

• An assessment of the current process before a tool is chosen
• A schedule, a risk list, and a single point of contact
• Status the contracting officer and the program office can both read
• Closeout that matches what the statement of work asked for

How does this SDVOSB develop and maintain technology?

Technology development covers full-stack web development, hosting, CRM and related software, and custom computer programming. Maintenance is what happens after go-live: hosting, support, and computer facilities management (NAICS 541513), plus data processing and hosting (NAICS 518210).

Relevant NAICS codes for build and sustainment:

• 541511 Custom Computer Programming Services
• 541512 Computer Systems Design Services
• 541519 Other Computer Related Services
• 541513 Computer Facilities Management Services
• 518210 Data Processing, Hosting, and Related Services
• 541339 Engineering Services

Commercial examples of the same engineering are business websites, custom software, mobile apps, and SaaS products. Government builds use the same disciplines, scoped to the agency requirement, including email, chat, SMS, and voice features when the statement of work includes them.

What else can an agency buy from us?

The five services above are the government focus. The capability statement also lists work agencies ask for alongside them:

• IT consulting, web and logo design, and websites with email, chat, SMS, and voice
• Automation, email, and social media marketing
• Human-resource consulting and productivity improvement
• Project staffing with specialists for an internal project (NAICS 561310)
• Temp-to-perm staffing so the agency can judge the work before a permanent hire (NAICS 561320)
• Office administrative services (NAICS 561110)
• Management consulting under NAICS 541611

Those lines are the same company. A website, a training class, and a program manager can sit on one scope when the requirement calls for all three.

How is the work priced?

The capability statement prices work from the scope, time, and budget of the project, and builds a package that matches those three constraints. That is the pricing rule for SDVOSB government services: a written scope, a schedule, and a fixed price before performance begins.

Commercial prices already published on this site show the private-sector baseline. They are not a government rate schedule. An agency quote follows the requirement.
